Dinosaurs In the News





'Bandit-masked' feathered dinosaur hid from predators using multiple types of camouflage   PhysOrg - October 26, 2017

By reconstructing the likely color patterning of the Chinese dinosaur Sinosauropteryx, researchers have shown that it had multiple types of camouflage which likely helped it to avoid being eaten in a world full of larger meat-eating dinosaurs, including relatives of the infamous Tyrannosaurus Rex, as well as potentially allowing it to sneak up more easily on its own prey.




Move aside T-Rex! New species of 'mega-carnivore' dinosaur roamed southern Africa 200 million years ago and was 'top of the food chain'   Daily Mail - October 26, 2017
A dinosaur as big as a bus roamed southern Africa 200 million years ago, scientists have revealed thanks to the discovery of several huge three-toed footprints. The new species, Kayentapus ambrokholohali, is a relative of Tyrannosaurus rex and was identified by its footprints, which are nearly two feet (23 inches) long. Dinosaurs are recorded as only first appearing on Earth around 230 million years ago, so the new find shocked researchers as it shows they grew big very quickly.




'Ugly' 16ft-long dinosaur is found in the south of France with terrifying 2.5-inch teeth that tore through food like scissors 80 million years ago   Daily Mail - October 26, 2017
The plant eater - which grew to more than 16 feet long - had an unusually short face with powerful jaws that enabled it to snack on tough riverside palm trees. Its two-and-a-half inch teeth worked 'like a pair of scissors' as it chewed the hard foliage, before swallowing.




New tyrannosaur fossil is most complete found in Southwestern US   Science Daily - October 19, 2017
A fossilized skeleton of a tyrannosaur discovered in Utah's Grand Staircase-Escalante National Monument was airlifted by helicopter Oct 15, and delivered to the Natural History Museum of Utah where it will be uncovered, prepared, and studied. The fossil is approximately 76 million years old and is likely an individual of the species Teratophoneus curriei.




How did dinosaurs evolve beaks and become birds? Scientists think they have the answer   PhysOrg - September 28, 2017

Once you know that many dinosaurs had feathers, it seems much more obvious that they probably evolved into birds. But there's still a big question. How did a set of dinosaurian jaws with abundant teeth (think T. rex) turn into the toothless jaws of modern birds, covered by a beak? Two things had to happen in this transition, suppression of the teeth and growth of the beak. Now new fossil evidence has shown how it happened.




Scientists track the brain-skull transition from dinosaurs to birds   Science Daily - September 11, 2017
The dramatic, dinosaur-to-bird transition that occurred in reptiles millions of years ago was accompanied by profound changes in the skull roof of those animals -- and holds important clues about the way the skull forms in response to changes in the brain -- according to a new study. It is the first time scientists have tracked the link between the brain's development and the roofing bones of the skull.




How dinosaurs evolved into birds - Scientists reveal how incredible transition 100 million years ago saw profound changes to animals' skulls   Daily Mail - September 11, 2017
The transition of dinosaurs to birds began around 100 million years ago, and a new study suggests that the changes during this time went well beyond the growth of feathers. New research indicates that the transition was also accompanied by profound changes to those animals' skulls. The findings hold important clues about the way the skull forms in response to changes in the brain, according to the researchers.




66 Million Years Ago, Bird-Like Dinosaurs Laid Blue-Green Eggs   NBC - August 31, 2017

A type of bird-like dinosaur that lived in what is now China during the Cretaceous period - about 145.5 million to 65.5 million years ago - laid eggs that had a bluish-green tint, the first evidence of pigment in dinosaur eggs, according to a new study. The well-preserved eggshells belonged to the oviraptorid Heyuannia huangi, and analysis revealed the hints of blue-green color, the researchers said. Oviraptorids were a small-bodied, short-snouted group of dinosaurs with toothless beaks, and are known from fossils found in Mongolia and China. Blue and green egg hues are found in eggs belonging to many types of modern birds, and were long thought to have originated in bird lineages. This new finding, however, implies that egg coloration appeared earlier in the dinosaur family tree, and might have emerged alongside nesting behavior that left eggs partially exposed in nest mounds, rather than buried underground.




So Long, Sue! Famed T. Rex Makes Way for Bigger Beast   Live Science - August 31, 2017

After spending nearly 18 years in the Field Museum's great hall in Chicago, Sue - the largest and most complete Tyrannosaurus rex ever discovered - will move to an exhibit upstairs, making room for the world's largest known dinosaur: a titanosaur.




Unique imaging of a dinosaur's skull tells evolutionary tale Researchers using Los Alamos' unique neutron-imaging and high-energy X-ray capabilities have exposed the inner structures of the fossil skull of a 74-million-year-old tyrannosauroid dinosaur nicknamed the Bisti Beast in the highest-resolution scan of tyrannosaur skull ever done. The results add a new piece to the puzzle of how these bone-crushing top predators evolved over millions of years.




Rare tooth find reveals horned dinosaurs in eastern North America   PhysOrg - May 24, 2017

A chance discovery in Mississippi provides the first evidence of an animal closely related to Triceratops in eastern North America. The fossil, a tooth from rocks between 68 and 66 million years old, shows that two halves of the continent previously thought to be separated by seaway were probably connected before the end of the Age of Dinosaurs. Horned dinosaurs, or ceratopsids, had previously only been found in western North America and Asia. A seaway down the middle of North America, which linked the Arctic Ocean and Gulf of Mexico, split the continent into eastern and western halves during much of the Late Cretaceous (around 95 to 66 million years ago). This means that animals that evolved in western North America after the split-including ceratopsids were prevented from traveling east.




  Tooth that proves 'Triceratops-style' horned dinosaurs roamed eastern US could rewrite our planet's history   Daily Mail - May 24, 2017
A chance discovery of a single tooth in Mississippi provides the first evidence of an animal closely related to Triceratops in eastern North America. Until now, most experts believed North America was split by a vast sea. However, this rare 68 to 66 million-year-old tooth suggests there was a bridge between the two sides.




First baby of a gigantic Oviraptor-like dinosaur belongs to a new species   PhysOrg - May 9, 2017

A new species of giant bird-like dinosaur - which tended to enormous nests that were bigger than a monster truck tire - has been discovered in Henan, China. The new species, named Beibeilong, lived about 90 million years ago during the Cretaceous Period. It is described by a joint Chinese-Canadian-Slovakia team based on a number of large eggs and an associated embryo that were collected in China




Mars volcano, Earth's dinosaurs went extinct about the same time   PhysOrg - March 20, 2017
Around the same time that the dinosaurs became extinct on Earth, a volcano on Mars went dormant, NASA researchers have learned. Arsia Mons is the southernmost volcano in a group of three massive Martian volcanoes known collectively as Tharsis Montes. Until now, the volcano's history has remained a mystery. But thanks to a new computer model, scientists were finally able to figure out when Arsia Mons stopped spewing out lava. According to the model, volcanic activity at Arsia Mons came to a halt about 50 million years ago. Around that same time, Earth experienced the Cretaceous-Paleogene extinction event, which wiped out three-quarters of its animal and plant species, including the dinosaurs.




How dinosaurs learned to stand on their own two feet   Science Daily - March 3, 2017

Paleontologists have developed a new theory to explain why the ancient ancestors of dinosaurs stopped moving about on all fours and rose up on just their two hind legs. Bipedalism in dinosaurs was inherited from ancient and much smaller proto-dinosaurs. The tails of proto-dinosaurs had big, leg-powering muscles. Having this muscle mass provided the strength and power required for early dinosaurs to stand on and move with their two back feet. We see a similar effect in many modern lizards that rise up and run bipedally. Over time, proto-dinosaurs evolved to run faster and for longer distances. Adaptations like hind limb elongation allowed ancient dinosaurs to run faster, while smaller forelimbs helped to reduce body weight and improve balance. Eventually, some proto-dinosaurs gave up quadrupedal walking altogether.




Paleontologist suggests path to flight for dinosaurs not as straight as thought   PhysOrg - February 25, 2017
When most people think of the evolution of a particular feature or ability, they tend to think of a straight line - a species develops a feature that allows it to do something better; its offspring also express that feature, and soon another feature is added until something like wings for flight develop.




First live birth evidence in dinosaur relative   BBC - February 16, 2017

Scientists have uncovered the first evidence of live births in the group of animals that includes dinosaurs, crocodiles and birds. All examples of this group, known as the Archosauromorpha, lay eggs. This led some scientists to wonder whether there was something in their biology that prevented live births. But examination of the fossil remains of a very long-necked, 245 million-year-old marine reptile from China revealed it was carrying an embryo.




Entire Chunk of Feathered Dinosaur Discovered in Amber   Scientific American - December 11, 2016

The color appears to have been chestnut brown on top and cream or white on the bottom, but it is possible the colors have been altered by, and it bears repeating here, the 99 million years they've spent in the ground.




Dino-bird fossil had sparkly feathers 'to attract mate '   BBC - November 15, 2016

An extinct bird that lived about 120 million years ago had iridescent feathers that it may have used to attract a mate, fossil evidence shows. The prehistoric bird, which was found recently in China, may have puffed up its feathers like a peacock. The bird's feathers are "remarkably preserved", including the chemical that gave them sparkle. The animal belongs to a group of early birds known as enantiornithines, which lived during the Age of the Dinosaurs. All known specimens come from rocks in Liaoning, China, which have yielded numerous fossils of feathered dinosaurs, primitive birds and pterosaurs.




Biggest map of dinosaur tree yet suggests they emerged 20 million years earlier than thought   PhysOrg - November 9, 2016

A team of researchers from the U.K. and the U.S. has mapped the biggest dinosaur tree yet, and in so doing, has found that the creatures may have evolved 20 million years earlier than most in the field have thought.




  The Incredible Reptiles That Flew 200 Million Years Ago   Smithsonian - November 7, 2016
A 200-million-year-old fossil reveals the amazing body structure of a reptilian creature known as the dimorphodon. Not only did it possess wings, it was one of the first large vertebrates to travel by air. (2:41)




Fossilized dinosaur brain tissue identified for the first time   Science Daily - October 28, 2016

Researchers have identified the first known example of fossilized brain tissue in a dinosaur from Sussex. The tissues resemble those seen in modern crocodiles and birds. An unassuming brown pebble, found more than a decade ago by a fossil hunter in Sussex, has been confirmed as the first example of fossilized brain tissue from a dinosaur. The fossil, most likely from a species closely related to Iguanodon, displays distinct similarities to the brains of modern-day crocodiles and birds. Meninges -- the tough tissues surrounding the actual brain -- as well as tiny capillaries and portions of adjacent cortical tissues have been preserved as mineralized 'ghosts'.




Giant dinosaur footprint discovered in Mongolia desert   PhysOrg - September 30, 2016

One of the biggest dinosaur footprints ever recorded has been unearthed in the Gobi Desert, researchers said Friday, offering a fresh clue about the giant creatures that roamed the earth millions of years ago. A joint Mongolian-Japanese expedition found the giant print, which measures 106 centimetres (42 inches) long and 77 centimetres wide. One of several footprints discovered in the vast Mongolian desert, the huge fossil was discovered last month in a geologic layer formed between 70 million and 90 million years ago, researchers said.




Ancient birds' wings preserved in amber   BBC - June 28, 2016

Two wings from birds that lived alongside the dinosaurs have been found preserved in amber. The "spectacular" finds from Myanmar are from baby birds that got trapped in the sticky sap of a tropical forest 99 million years ago. Exquisite detail has been preserved in the feathers, including traces of colour in spots and stripes. The wings had sharp little claws, allowing the juvenile birds to clamber about in the trees. The tiny fossils, which are between two and three centimetres long, could shed further light on the evolution of birds from their dinosaur ancestors.




Rare Dinosaur - Era Bird Wings Found Trapped in Amber   National Geographic - June 28, 2016

Bone, tissue, and feathers show the almost 100-million-year-old wings are remarkably similar to those on modern birds. Two tiny wings entombed in amber reveal that plumage (the layering, patterning, coloring, and arrangement of feathers) seen in birds today already existed in at least some of their predecessors nearly a hundred million years ago. They most likely he belonged to enantiornithes, a group of avian dinosaurs that became extinct at the end of the Cretaceous period. Skin, muscle, claws, and feather shafts are visible, along with the remains of rows of feathers similar in arrangement and microstructure to modern birds.




Dinosaurs Migrated Out of Europe as Ancient Supercontinent Broke Up   Live Science - April 29, 2016

Between 230 million and 66 million years ago, dinosaurs plodded across the supercontinent Pangea, and migrated from Europe to other parts of the world. Now, by gathering and comparing all the data about their fossils, paleontologists have been able to visually map the dinosaurs' migration during the time they ruled the Earth. The researchers used "network theory" in a new way to see how different dinosaur fossils were connected.




Newly discovered titanosaurian dinosaur from Argentina, Sarmientosaurus   Science Daily - April 26, 2016
Approximately 95-million-year-old complete sauropod skull examined, possibly exceptional sensory capabilities. Scientists have discovered Sarmientosaurus musacchioi, a new species of titanosaurian dinosaur, based on an complete skull and partial neck fossil unearthed in Patagonia, Argentina, according to a new study. The researchers found that the Sarmientosaurus brain was small relative to its enormous body, typical of sauropods. However, they also found evidence of greater sensory capabilities than most other sauropods. They suggest that Sarmientosaurus had large eyeballs and good vision, and that the inner ear may have been better tuned for hearing low-frequency airborne sounds compared to other titanosaurs. Moreover, the balance organ of the inner ear indicates that this dinosaur may have habitually held its head with the snout facing downward, possibly to feed primarily on low-growing plants.




Dinosaurs 'in decline' 50 million years before asteroid strike   BBC - April 18, 2016

The new assessment adds further fuel to a debate on how dinosaurs were doing when a 10km-wide space rock slammed into Earth 66 million years ago. A team suggests the creatures were in long-term decline because they could not cope with the ways Earth was changing.




Deceptive feathered dinosaur finally gets a name   PhysOrg - April 18, 2016

Solving one of the longest cases of mistaken identity, University of Alberta PhD candidate Greg Funston recently described a new genus and species of toothless dinosaur from Alberta. Long thought to be a more common ornithomimid, Apatoraptor pennatus instead turned out to be a member of the notoriously enigmatic caenagnathid family.




Jurassic Park Just Got Real? Chicken Embryo Grown With Dinosaur Legs   Morning News USA - March 17, 2016

It's a known fact in the field of science that birds and chickens, for that matter, are dinosaurs. They are among the present-day animals that are direct descendants of long-gone dinosaurs. Over the course of millions of years, birds, to which chickens belong, have evolved and survived the test of time. But through the course of millions of years, chickens have lost some of the primitive traits and features of their ancestors. One of which is their humongous and powerful lower legs.




Scientists develop chick with 'dinosaur' feet: study   PhysOrg - March 17, 2016
Scientists in Chile have created a chicken embryo that developed dinosaur-like feet after genetic manipulation, highlighting the evolutionary link between theropod dinosaurs and birds. The research shows that "by inhibiting early maturation of a leg of the chicken embryo, the leg reverts to the shape that dinosaurs' legs had. The research should help shed new light not just on the links between birds and dinosaurs, but on the genetic changes involved in the evolution




Molecular experiment reverses evolution in birds obtaining a dinosaur-like lower leg   PhysOrg - March 11, 2016
Anyone who has eaten roasted chicken can account for the presence of a long, spine-like bone in the drumstick. This is actually the fibula, one of the two long bones of the lower leg (the outer one). In dinosaurs, the ancestors of birds, this bone is tube-shaped and reaches all the way down to the ankle. However, in the evolution from dinosaurs to birds, it lost its lower end, and no longer connects to the ankle, being shorter than the other bone in the lower leg, the tibia. Scientists noted long ago that bird embryos first develop a tubular, dinosaur-like fibula. Afterward, it becomes shorter than the tibia and acquires its adult, splinter-like shape.




Research team identifies rare dinosaur from Appalachia   PhysOrg - January 23, 2016
An international team of researchers has identified and named a new species of dinosaur that is the most complete, primitive duck-billed dinosaur to ever be discovered in the eastern United States. They named the new dinosaur Eotrachodon orientalis, which means dawn rough tooth from the east. The name pays homage to "Trachodon," which was the first duck-billed dinosaur named in 1856.




Geologist says dinosaur fossils found in western India   PhysOrg - January 23, 2016
The team, of 10 mainly German and Indian archaeologists and researchers, dug up the fossils during excavations in Gujarat's marshy coastal district of Kutch, Gaurav Chauhan said.




Fossil dinosaur tracks give insight into lives of prehistoric giants   PhysOrg - December 1, 2015

A newly discovered collection of rare dinosaur tracks is helping scientists shed light on some of the biggest animals ever to live on land. Hundreds of footprints and handprints made by plant-eating sauropods around 170 million years ago have been found on the Isle of Skye in Scotland. The discovery - which is the biggest dinosaur site yet found in Scotland - helps fill an important gap in the evolution the huge, long-necked animals, which were the biggest of the dinosaurs.




Ornithomimus dinosaur with preserved tail feathers and skin tightens linkages between dinosaurs and birds   PhysOrg - October 28, 2015

An undergraduate University of Alberta paleontology student has discovered an Ornithomimus dinosaur with preserved tail feathers and soft tissue. The discovery is shedding light on the convergent evolution of these dinosaurs with ostriches and emus relating to thermoregulation and is also tightening the linkages between dinosaurs and modern birds.




Baby Duck-Billed Dinos Unearthed in 'Dragon's Tomb' Nest   Live Science - October 14, 2015
A cluster of baby duck-billed dinosaurs - hadrosaurs like the adorable character Ducky in the 1988 animated film "The Land Before Time" - was uncovered in a slab of rock from a fossil-rich part of Mongolia known as "Dragon's Tomb." Scientists examining a roughly 1-foot-long (0.3 meters) piece of rock from the Dragon's Tomb site, which is located in the Gobi Desert, discovered at least three new baby Saurolophus angustirostris fossils. The rock was part of a dinosaur nest and contained some interesting bones, but until now, scientists didn't know exactly what those bones were. The new discovery, akin to finding a whole new chapter in a family photo album, could help researchers piece together the entire Saurolophus family tree. Saurolophus were large duck-billed hadrosaurs with distinctive crests on the top of their heads. But the newly identified fossils weren't very large at all, the scientists said. In fact, the newfound hadrosaurs were probably at the very earliest stages of life - either they had just hatched, or were just about to.




Dinosaurs became birds
  Dinosaur find: Velociraptor ancestor was 'winged dragon'   BBC - July 16, 2015

Scientists have discovered a winged dinosaur - an ancestor of the velociraptor - that they say was on the cusp of becoming a bird. The 6ft 6in (2m) creature was almost perfectly preserved in limestone, thanks to a volcanic eruption that had buried it in north-east China. And the 125-million year-old fossil suggests many other dinosaurs, including velociraptors, would have looked like "big, fluffy killer birds".




  End of the dinosaurs gave rise to the modern 'Age of Fishes,' researchers find   PhysOrg - June 30, 2015
A pair of paleobiologists from Scripps Institution of Oceanography, UC San Diego have determined that the world's most numerous and diverse vertebrates - ray-finned fishes - began their ecological dominance of the oceans 66 million years ago, aided by the mass extinction event that killed off dinosaurs. Mammals evolved 250 million years ago but didn't become really important until after the mass extinction. Ray-finned fishes have the same kind of story. The lineage has been around for hundreds of millions of years, but without the mass extinction event 66 million years ago, it is very likely that the oceans wouldn't be dominated by the fish we see today.




Why did the dinosaur cross the equator, then not stay there?   Science Daily - June 15, 2015
For more than 30 million years after dinosaurs first appeared, they remained inexplicably rare near the equator, where only a few small-bodied meat-eating dinosaurs eked out a living. The age-long absence of big plant-eaters at low latitudes is one of the great, unanswered questions about the rise of the dinosaurs. And now the mystery has a solution, according to an international team of scientists who pieced together a remarkably detailed picture of the climate and ecology more than 200 million years ago at Ghost Ranch in northern New Mexico, a site rich with fossils from the Late Triassic Period.




How Dinosaurs Shrank and Became Birds   Scientific American - June 13, 2015
Modern birds descended from a group of two-legged dinosaurs known as theropods, whose members include the towering Tyrannosaurus rex and the smaller velociraptors. The theropods most closely related to avians generally weighed between 100 and 500 pounds - giants compared to most modern birds - and they had large snouts, big teeth, and not much between the ears. A velociraptor, for example, had a skull like a coyote’s and a brain roughly the size of a pigeon’s.




Researchers hot on the trail of Velociraptor relative   Science Daily - June 11, 2015
In a discovery seemingly straight from the movie 'Jurassic World,' researchers have just documented a rich fossil footprint site in central China containing tracks by several kinds of dinosaurs, including raptors. From these tracks, the team has gained new insights into how raptors moved.




Were Dinosaurs Warm-Blooded? New Study Fuels Debate   - June 11, 2015
Dinosaurs were once thought to be the cold-blooded kings of the Mesozoic era. But new research on their growth rates suggests the prehistoric beasts grew just as fast as mammals, indicating they were warm-blooded creatures. However, not everyone agrees with the results, and some paleontologists suggest dinosaurs fell in the middle of the cold-blooded (ectotherm) and warm-blooded (endotherm) spectrum, making them intermediate-blooded (mesotherms).




Preserved dinosaur cells found, but scientists still can't build Jurassic World   PhysOrg - June 10, 2015
The science behind the Jurassic Park films always seemed far-fetched, even before the latest installment, Jurassic World, introduced the idea of genetically engineered super-dinosaurs. For one thing, finding mosquitoes that had drunk the blood of dinosaurs and then been preserved in amber for hundreds of millions of years is incredibly unlikely. But there's another more important reason: organic molecules such as proteins and DNA degrade fast after a creature's death. They are almost never found preserved in bones older than a few thousand years. This has been the dogma for many years.




Wales' 'first meat-eating' Jurassic dinosaur on show   BBC - June 9, 2015
A fossilized skeleton of a meat-eating Jurassic dinosaur found on a south Wales beach is being revealed to the public for the first time. The small theropod dinosaur - a distant cousin of the giant Tyrannosaurus rex - was uncovered by spring storms in 2014 at Lavernock, Vale of Glamorgan.




'Blood cells' found in dino fossils   BBC - June 9, 2015
Researchers have discovered what appear to be the remnants of red blood cells and connective tissue in 75 million-year-old dinosaur fossils. The work could shine a light on long-standing questions about dinosaur physiology, including whether specific species were warm- or cold-blooded. Chemical analysis revealed similarities between blood cells from fossils and those from living emu.




Feathered Fossils Give Scaly Dinosaurs a Makeover   National Geographic - December 10, 2014

Which came first, the feathers or the birds? Feathers first, scientists now say definitively. Yet this feathery revelation doesn't arise from discoveries of ancient birds, but of birds' ancestors - dinosaurs.




Oldest horned dinosaur species in North America found in Montana   PhysOrg - December 10, 2014

The limited fossil record for neoceratopsian - or horned dinosaurs - from the Early Cretaceous in North America restricts scientists' ability to reconstruct the early evolution of this group. The authors of this study have discovered a dinosaur skull in Montana that represents the first horned dinosaur from the North American Early Cretaceous that they can identify to the species level.




Mystery of dinosaur with giant arms solved   BBC - October 22, 2014

For half a century, all that was known about this dinosaur was that it had enormous forearms, measuring 2.4m-long (8ft) and tipped with three giant claws. Its name Deinocheirus mirificus means unusual, horrible hands. In various reconstructions, it has been imagined as anything from a T. rex-type predator grasping at prey with its claws, to a giant, sloth-like climber, using its arms to dangle from trees. But the discovery of two nearly complete skeletons in Mongolia have finally laid this speculation to rest. The international research team says the beast was very large, measuring about 11m (36ft) long and weighing six tons. It had an elongated head with a duck-like beak, and a large humped sail on its back.




New dinosaur species unearthed in Venezuela   PhysOrg - October 8, 2014
A team of paleontologists with members from Brazil, Venezuela, the U.S. and Germany has found fossil evidence of a previously unknown dinosaur in Venezuela. Because the bone fossils were found in the Venezuelan state of Tachira the dino has been named Tachiraptor admirabilis, a relatively small dinosaur believed to have measured just 1.5 meters from the tip of its nose to the end of its tail. The research team believes the bones date to approximately 201 million years ago. That would put the creature that left them behind as living just a million years after the mass extinction that marked the conclusion of the Triassic period and the beginning stages of the Jurassic.




How dinosaur arms turned into bird wings   Science Daily - September 30, 2014
Although we now appreciate that birds evolved from a branch of the dinosaur family tree, a crucial adaptation for flight has continued to puzzle evolutionary biologists. During the millions of years that elapsed, wrists went from straight to bent and hyperflexible, allowing birds to fold their wings neatly against their bodies when not flying. A resolution to this impasse is now provided by an exciting new study.




  Dinosaur With Mysteriously Large Nose Discovered in Utah   Epoch Times - September 24, 2014

Rhinorex condrupus was recently discovered in Utah. And that thing on the front of its head? That’s its nose. Rhinorex was actually dug up in the 1990s, but it was never put together. It was just kept in storage at Brigham Young University. Finally, two scientists decided to piece the fossils together, and that’s when they realized they had a new species on their hands.

Hadrosaur with huge nose discovered: Function of dinosaur's unusual trait a mystery   Science Daily - September 24, 2014
Call it the Jimmy Durante of dinosaurs - a newly discovered hadrosaur with a truly distinctive nasal profile. The new dinosaur, named Rhinorex condrupus by paleontologists, lived in what is now Utah approximately 75 million years ago during the Late Cretaceous period.




  Meet Dreadnoughtus, perhaps the biggest creature to ever walk the planet   CNN - September 6, 2014
The Dreadnoughtus schrani dinosaur unveiled Thursday was one of the biggest -- if not THE biggest -- land animal ever to grace the Earth.




Nest of Young Dinosaurs with 'Babysitter' Discovered   Live Science - September 3, 2014
A nest of baby dinosaurs with what might have been a juvenile babysitter sitting atop them has been discovered in China, researchers say. These findings help shed light on how sociable these ancient reptiles might have been, scientists added. The oldest known dino nesting sites are 190 million years old, and their existence suggests that even the earliest dinosaurs may have exhibited complex family behaviors.




Dinosaurs 'shrank' regularly to become birds   BBC - July 31, 2014

Huge meat-eating, land-living dinosaurs evolved into birds by constantly shrinking for over 50 million years, scientists have revealed. Theropods shrunk 12 times from 163kg (25st 9lb) to 0.8kg (1.8lb), before becoming modern birds. The researchers found theropods were the only dinosaurs to get continuously smaller. Their skeletons also changed four times faster than other dinosaurs, helping them to survive.




  'Fluffy and feathery' dinosaurs were widespread   BBC - July 25, 2014
All dinosaurs were covered with feathers or had the potential to grow feathers, a study suggests. The discovery of 150-million-year-old fossils in Siberia indicates that feathers were much more widespread among dinosaurs than previously thought.




Four-winged flying dinosaur unearthed in China   The Guardian - July 15, 2014

A new species of prehistoric, four-winged dinosaur discovered in China may be the largest flying reptile of its kind. The well-preserved, complete skeleton of the dinosaur Changyuraptor yangi features a long tail with feathers 30cm in length - the longest ever seen on a dinosaur fossil. The feathers may have played a major role in flight control, say scientists in the latest issue of Nature Communications, in particular allowing the animal to reduce its speed to land safely.




Birdlike fossil challenges notion that birds evolved from ground-dwelling dinosaurs   Science Daily - July 10, 2014
The re-examination of a sparrow-sized fossil from China challenges the commonly held belief that birds evolved from ground-dwelling theropod dinosaurs that gained the ability to fly. The birdlike fossil is actually not a dinosaur, as previously thought, but much rather the remains of a tiny tree-climbing animal that could glide.




Say Hello to a Horned Dinosaur With 'Wings' on Its Head   NBC - June 19, 2014

The latest name in dinosaurs is Mercuriceratops gemini - a bizarre horned dinosaur that had a frill so wide it looked the wings on the Greek god Mercury's helmet. At least that's what the scientists who named the beast thought. That's how they came up with the genus name, which is derived from the Greek for "Mercury horned-face." The 77 million-year-old plant-eater is described and classified in a paper published online by the journal Naturwissenschaften. The "gemini" refers to the fact that almost identical twin specimens of the species' skull were found in north central Montana's Judith River Formation and Alberta's Dinosaur Provincial Park.




Dinosaurs 'neither warm nor cold blooded'   BBC - June 12, 2014
Dinosaurs fit in an intermediate class between warm and cold blooded animals, a study in the journal Science claims. Scientists compared the growth rates of hundreds of living and extinct species, using growth rings and bone size to calculate the rates for dinosaurs.




  'Biggest dinosaur ever' discovered   BBC - May 17, 2014
Fossilized bones of a dinosaur believed to be the largest creature ever to walk the Earth have been unearthed in Argentina, paleontologists say. Based on its huge thigh bones, it was 40m (130ft) long and 20m (65ft) tall.




New Tyrannosaur named 'Pinocchio rex'   BBC - May 7, 2014

A new type of Tyrannosaur with a very long nose has been nicknamed "Pinocchio rex". The ferocious carnivore, nine metres long with a distinctive horny snout, was a cousin of Tyrannosaurus rex. Researchers now think several different tyrannosaurs lived and hunted alongside each other in Asia during the late Cretaceous Period, the last days of the dinosaurs.




Ancient Crocodilians Used 'Death Rolls' to Kill Dinosaurs   Scientific American - May 7, 2014
Ancient giant crocodilians killed dinosaur prey by spinning their bodies in "death rolls," tearing off the beasts' flesh and limbs, researchers say. These new findings shed light on the way ancient reptiles interacted with their environments. Crocodilians include the largest of all reptiles alive today, the saltwater crocodile, a deadly carnivore that can grow at least 23 feet (7 meters) long and weigh more than 2,200 lbs. (1,000 kilograms). These predators will eat just about anything they can, including sharks. (Although these reptiles do kill people, far more people die of bee stings each year than crocodile attacks.)




Revealing the healing of 'dino-sores': Examining broken bones in 150-million-year-old predatory dinosaur   Science Daily - May 7, 2014

Scientists have used state-of-the-art imaging techniques to examine the cracks, fractures and breaks in the bones of a 150-million-year-old predatory dinosaur. The research sheds new light, literally, on the healing process that took place when these magnificent animals were still alive.




All teeth and claws? New study sheds light on dinosaur claw function   Science Daily - May 7, 2014

How claw form and function changed during the evolution from dinosaurs to birds is explored in a new study into the claws of a group of theropod dinosaurs known as therizinosaurs. Theropod dinosaurs, a group which includes such famous species as Tyrannosaurus rex and Velociraptor, are often regarded as carnivorous and predatory animals, using their sharp teeth and claws to capture and dispatch prey. However, a detailed look at the claws on their forelimbs revealed that the form and shape of theropod claws are highly variable and might also have been used for other tasks.




First Malaysian dinosaur fossil found, researchers say   PhysOrg - February 19, 2014
A Malaysian university unveiled on Wednesday what researchers called the first dinosaur fossil ever found in the country - the tooth of a fish-eating predator estimated to be at least 75 million years old.




First dinosaurs identified from Saudi Arabia   PhysOrg - January 7, 2014
Dinosaur fossils are exceptionally rare in the Arabian Peninsula. An international team of scientists from Uppsala University, Museum Victoria, Monash University, and the Saudi Geological Survey have now uncovered the first record of dinosaurs from Saudi Arabia.




Dinosaur Fossil With Fleshy Rooster's Comb Is First of Its Kind   National Geographic - December 12, 2013

A rare, mummified specimen of the duck-billed dinosaur Edmontosauraus regalis shows for the first time that those dinosaurs' heads were adorned with a fleshy comb, most similar to the roosters' red crest.




Boneheaded Dinosaurs Butted Heads In Combat   Live Science - July 18, 2013
Dinosaurs with giant domes on their heads may have used their extra padding for head butting, new research suggests. An analysis of pachycephalosaurid skulls revealed head wounds likely incurred during combat. The pattern of wounds, described July 16 in the journal PLOS ONE, suggest the dome-headed dinos butted heads, just as bighorn sheep do today.




Nasutoceratops: 'Big-nose, horn-face' dinosaur described   BBC - July 16, 2013

An unusual new species of dinosaur, unearthed from the deserts of Utah, has been described by scientists. The 5m-long (15ft) beast is a member of the triceratops family, but with a huge nose and exceptionally long horns, palaeontologists say it is unlike anything they have seen before. It has been named accordingly as Nasutoceratops titusi, which means big-nose, horn-face.




Dinosaur Eggs Are Missing Link In Egg Evolution   National Geographic - May 31, 2013
Studying dinosaur eggs is a lot like a big, frustrating Easter egg hunt: The eggs are rare, fragile - rainwater is acidic enough to dissolve some egg fossils - and it can be difficult to identify which dinosaur species they belong to. But every now and then, scientists' persistence pays off. A recently discovered clutch of 150-million-year-old fossil eggs is being billed as an important missing link in the evolution of dinosaur eggs.




Ancient bone-headed dinosaur found   BBC - May 8, 2013

Scientists have unveiled a new species of bone-headed dinosaur, which they say is the oldest in North America, and possibly the world. The dog-sized plant-eater had a dome-shaped skull that may have been used to head-butt other dinosaurs.




Dinosaur embryo fossils reveal life inside the egg   BBC - April 10, 2013
Scientists have gained a remarkable insight into some of the oldest dinosaur embryos ever found. The remains of the creatures were unearthed in south west China and are about 190 million years old.




Crow-Size Pterosaur Named After 9-Year-Old Fossil Hunter   National Geographic - March 24, 2013
A new species of crow-size pterosaur has been named in honor of the nine-year-old fossil hunter who discovered it, a new study says. The new species of pterosaur - a type of flying reptile that lived alongside the dinosaurs - was dubbed Vectidraco daisymorrisae after U.K. youngster Daisy Morris.




Jet-Size Pterosaurs Took Off from Prehistoric Runways   Live Science - November 8, 2012
It's a bird … It's a plane … It's a plane-size bird! If humans had lived 67 million years ago in what is now Texas, they would've had a hard time missing the giant flying pterosaur called Quetzalcoatlus, which was the size of an F-16 fighter jet. The biggest animal ever to fly in the history of the world, this pterosaur dominated the sky with its 34-foot (10 meters) wingspan. Fossils of the creature have been found in Big Bend National Park, in an area that was heavily forested in the late Cretaceous. But this presents a puzzle: How did it fly? The region lacked the cliffs that make flight for such large birds easy to conceive. A new computer simulation has the answer: These beasts used downward-sloping areas, at the edges of lakes and river valleys, as prehistoric runways to gather enough speed and power to take off.




2-Ton 'Alien' Horned Dinosaur Discovered   Live Science - November 8, 2012
Paleontologists in Canada have discovered fossils of a new 2-ton, 20-foot-long horned dinosaur that roamed the Earth about 80 million years ago. And its headgear would've put on quite a show for the ladies. The dinosaur, a distant cousin of Triceratops called Xenoceratops foremostensis, is one of the oldest specimens known to date of the ceratopsid group. The beast's name, Xenoceratops, translates to "alien horned-face," referring to its strange pattern of horns on its head and above its brow, and the rarity of such horned dinosaurs in this part of the fossil record.




New "Sauron" Dinosaur Found, Big as T. Rex   National Geographic - November 7, 2012
Named after the demonic Eye of Sauron from the Lord of the Rings films, a new species of flesh-ripping dinosaur terrorized North Africa some 95 million years ago, a new study says.




Flying Dino Too Weak to Lift Off?   Discovery - November 8, 2012
Pterodactyls had the wingspan of a F-16 fighter, but they may have been too out of shape to fly. A new analysis of the largest of pterodactyls suggests they were too big and their muscles too weak to vault into the air and fly. Instead, they were right at the upper limit of animal flight and needed a hill or stiff breeze so they could soar like hang gliders.




Dinosaur Die out Might Have Been Second of Two Closely Timed Extinctions   Science Daily - September 6, 2012
The most-studied mass extinction in Earth history happened 65 million years ago and is widely thought to have wiped out the dinosaurs. New University of Washington research indicates that a separate extinction came shortly before that, triggered by volcanic eruptions that warmed the planet and killed life on the ocean floor.




Huge Asteroid Is Still the Central Villain in Dinosaurs’ Extinction   New York Times - May 7, 2012
For some 30 years, scientists have debated what sealed the fate of the dinosaurs. Was an asteroid impact more or less solely responsible for the catastrophic mass extinction at the end of the Cretaceous geological period, 65 million years ago? Or were the dinosaurs already undergoing a long-term decline, and the asteroid was merely the coup de grace?




Australia had 'globe-trotting' dinosaurs: study   PhysOrg - May 7, 2012
Scientists said Monday a new fossil discovery suggested Australia's dinosaurs were cosmopolitan globe-trotters, unlike the "unique weirdos" of its current wildlife. Palaeontologist Erich Fitzgerald said an ankle bone fossil found 87 kilometres (54 miles) from Melbourne indicated that meat-eating dinosaurs known as ceratosaurs lived in what is now Australia some 125 million years ago.




Dinosaur gases 'warmed the Earth'   BBC - May 7, 2012
Giant dinosaurs could have warmed the planet with their flatulence, say researchers. British scientists have calculated the methane output of sauropods, including the species known as Brontosaurus. By scaling up the digestive wind of cows, they estimate that the population of dinosaurs - as a whole - produced 520 million tonnes of gas annually. They suggest the gas could have been a key factor in the warm climate 150 million years ago.




First Dinosaur Discovered in Spain Is Younger Than Believed   Live Science - March 12, 2012
The first dinosaur ever found in Spain is not as old as paleontologists had believed - though at 130 million years old, the long-necked creature is no spring chicken. The dinosaur, Aragosaurus ischiaticus, was originally discovered in 1987. But the fossil was difficult to date. Now, researchers at the University of Zaragoza's Aragon Research Institute of Environmental Sciences have found the sauropod's age was estimated at 15 million years too old. The age-shaving results suggest the dinosaur was an ancestor of the enormous Titanosauriforms, a group that includes the largest dinosaurs to ever live. The new age estimate puts the dinosaur in the Hauterivian age between 136 million and 130 million years ago, the researchers reported March 12 in the journal Geological Magazine. <




Caught in the Act: Ancient Armored Fish Downs Flying Reptile   Live Science - March 9, 2012

An ancient armored fish was fossilized in the act of attacking and drowning a pterosaur in a toxic Jurassic lake, revealing that the winged reptiles were victims of a wide variety of carnivores, scientists find. Pterosaurs dominated the skies during the Age of Dinosaurs. Still, flight did not always ensure them safety - researchers have recently discovered that Velociraptor dined on the flying reptiles.




Velociraptor's last meal revealed   BBC - March 7, 2012
The bone of a large flying reptile has been found in the gut of a Velociraptor, sparking fresh discussion among paleontologists. Velociraptors have previously been described as "hyper predators". However, scientists suggest this pterosaur was too large to be the Velociraptor's intended prey but could have been scavenged. An international team of scientists revealed the drama of 75 million years ago with a detailed analysis of the skeleton found in the Gobi desert, Mongolia. A famous fossil unearthed in 1971 known as the "fighting dinosaurs" shows a Velociraptor and larger Protoceratops apparently locked in combat.




Triceratops and Torosaurus dinosaurs 'two species, not one'   BBC - March 1, 2012

A study has rejected claims that Triceratops and the lesser-known Torosaurus are one and the same type of dinosaur. Nicholas Longrich and Daniel Field, of Yale University, looked at 35 specimens ascribed to both species and concluded they represented two distinct creatures. "We looked at a bunch of changes in the skulls as the animals age and used a programme to arrange the skulls from youngest to oldest," explained Dr Longrich to BBC News. "What we found is there are young Torosaurus individuals and very old Triceratops individuals and that's inconsistent with Torosaurus being an adult Triceratops."




Dinosaurs had fleas too -- giant ones, fossils show   PhysOrg - February 29, 2012
In the Jurassic era, even the flea was a beast, compared to its minuscule modern descendants. These pesky bloodsuckers were nearly an inch long. New fossils found in China are evidence of the oldest fleas - from 125 million to 165 million years ago, said Diying Huang of the Nanjing Institute of Geology and Paleontology. Their disproportionately long proboscis, or straw-like mouth, had sharp weapon-like serrated edges that helped them bite and feed from their super-sized hosts, he and other researchers reported today.




T. rex bite was world's strongest   BBC - February 29, 2012
Tyrannosaurus rex had the most powerful bite of any creature that has ever walked the Earth, say scientists. Previous estimates of the prehistoric predator's bite suggested it was much more modest - comparable to modern predators such as alligators. This measurement, based on a laser scan of a T. rex skull, showed that its bite was equivalent to three tonnes - about the weight of an elephant.




Study says T. rex has most powerful bite of any terrestrial animal   PhysOrg - February 28, 2012
Research at the University of Liverpool, using computer models to reconstruct the jaw muscle of Tyrannosaurus rex, has suggested that the dinosaur had the most powerful bite of any living or extinct terrestrial animal. Previous studies have estimated that T. rex's bite had a force of 8000 to 13,400 Newtons, but given the size of the animal, thought to weigh more than 6000kg, researchers suspected that its bite may have been more powerful than this. Liverpool scientists developed a computer model to reverse engineer the animal's bite, a method that has previously been used to predict dinosaur running speeds.




Dinosaur forests mapped   PhysOrg - February 28, 2012
The first detailed maps of the Earth's forests at the time of the dinosaurs have been drawn up. The patterns of vegetation, together with information about the rate of tree growth, support the idea that the Earth was stifling hot 100 million years ago.




Oldest dinosaur nest site found   BBC - January 24, 2012
A nesting site for dinosaur eggs found in South Africa is 100 million years older than the previous oldest site. Paleontologists found 10 separate nests, each containing clutches of up to 34 eggs measuring 6-7cm. The fossils are of the prosauropod Massospondylus, a relative of the long-necked sauropods such as Diplodocus. They suggest that Massospondylus returned to the site repeatedly, laying their eggs in groups in the earliest-known case of "colonial nesting".




Meet America's biggest dinosaur   MSNBC - December 7, 2011
Here's a trivia question for your dino-crazy kids: What's the biggest dinosaur to roam North America? Paleontologists report that it's Alamosaurus sanjuanensis, one of many breeds of long-necked, long-tailed sauropods to roam the continent 69 million years ago.




North America's Biggest Dinosaur Revealed   Science Daily - December 7, 2011
New research from Montana State University's Museum of the Rockies and the State Museum of Pennsylvania has unveiled enormous bones from North America's biggest dinosaur.




Massive volcanoes, meteorite impacts delivered one-two death punch to dinosaurs: study   PhysOrg - November 17, 2011
A cosmic one-two punch of colossal volcanic eruptions and meteorite strikes likely caused the mass-extinction event at the end of the Cretaceous period that is famous for killing the dinosaurs 65 million years ago, according to two Princeton University reports that reject the prevailing theory that the extinction was caused by a single large meteorite.




15 Infant Dinosaurs Discovered Crowded in Nest   Live Science - November 17, 2011
A nest of 15 young dinosaurs uncovered in Mongolia - cousins of Triceratops - now suggests these plant-eating beasts might have cared for their young, scientists reveal. The dinosaur is named Protoceratops andrewsi, a sheep-size herbivore that lived about 70 million years ago that's known for the frill at the back of its head. Within the nest were infants about 4 to 6 inches (10 to 15 centimeters) long and probably no more than a year old.




First Long-Necked Dinosaur Fossil Found In Antarctica   Live Science - November 5, 2011
It's official, long-necked sauropod dinosaurs once roamed every continent on Earth - including now-frigid Antarctica. The discovery of a single sauropod vertebra on James Ross Island in Antarctica reveals that these behemoths, which included Diplodocus, Brachiosaurus and Apatosaurus, lived on the continent in the upper Cretaceous Period about 100 million years ago. "Sauropods were found all around the world, except Antarctica," said study researcher Ariana Paulina Carabajal, a paleontologist at the Carmen Funes Municipal Museum in Plaza Huincul, Argentina. "Until now."




Archaeopteryx was first bird after all   PhysOrg - October 26, 2011
The crown of the famous 150-million-year-old Archaeopteryx fossil as the first bird has been restored by a new evolutionary tree. Archaeopteryx had been considered for 150 years to be the first known bird since the first complete specimen was found in Germany in 1861, revealing a combination of reptilian and and bird features. But Chinese researchers asserted recently that a new and closely related fossil, Xiaotingia zhengi, was a bird-like dinosaur - therefore suggesting that Archaeopteryx was also a dinosaur.




Dinosaurs Migrated, Tooth Fossils Confirm   Live Science - October 26, 2011
By analyzing fossilized dinosaur teeth, researchers determined that the dinosaurs migrated hundreds of miles from their home to find food and water during dry spells. This is the first direct evidence supporting the theory that certain types of dinosaurs migrated to avoid seasonal food slumps. "Sauropods in western North America were living in an environment that was seasonally dry, that has a pronounced wet season and a pronounced dry season," said study researcher Henry Fricke of Colorado College. "If you have an animal that needs to eat a lot and drink a lot, it's going to have to move to access vegetation and to get water."




Fossil of an Armored Dinosaur Hatchling: Youngest Nodosaur Ever Discovered   Science Daily - September 27, 2011
It is the youngest nodosaur ever discovered, and a founder of a new genus and species that lived approximately 110 million years ago during the Early Cretaceous Era. Nodosaurs have been found in diverse locations worldwide, but they've rarely been found in the United States.




Tiniest Baby Dinosaur Discovered by Amateur Fossil Hunter   Live Science - September 16, 2011
On a mid-afternoon stroll with his wife on a Sunday in January 1997, amateur dinosaur hunter Ray Stanford stumbled upon something extraordinary. While walking in the riverbed near his home in College Park, Md., he found the tiniest example of an armored dinosaur anyone has ever seen. It took awhile for Stanford to realize the find he had on his hands. The impression left by the 5-inch (13 centimeter) baby dinosaur was covered in silt from the riverbed. One night, when a dim overhead kitchen light hit the stone in the right way, the shadows highlighted what was really there, the impression of a tiny dinosaur.




Pictures: "Incredible" Dinosaur Feathers Found in Amber   National Geographic - September 16, 2011
Preserved for 70 to 85 million years, these feathers are part of a newly revealed trove of likely dinosaur and bird plumage found trapped in amber in Alberta, Canada. The unusual find suggests a wide array of plumed creatures populated the time period - sporting everything from seemingly modern feathers to their filament-like forebears - and that even by this early date, feathers had become specialized, for example, for diving underwater, a new study says.




Tiny Dinosaurs Left Footprints On Ancient South Pole   Live Science - August 10, 2011

Several groups of dinosaurs that were roaming the South Pole more than 100 million years ago left three-toed prints in the wet, sandy soil. As they became compacted into cliffs, the prints waited patiently for Anthony Martin of Emory University to stumble across them in what is now Victoria, Australia. He found 24 complete prints.




Giant fossil shows huge birds lived among dinosaurs   BBC - August 10, 2011
An enormous jawbone found in Kazakhstan is further evidence that giant birds roamed - or flew above - the Earth at the same time as the dinosaurs.




Enormous bird lived alongside dinosaurs   MSNBC - August 10, 2011
All that's left of this big bird is its toothless lower jaw. The structure and characteristics of the jaw are associated with birds and not non-avian dinosaurs, the researchers believe. They conclude that the skull of the bird during its lifetime would have been about a foot long. If flightless, it could have stood close to 10 feet tall. If it flew, its wingspan is likely to have exceeded 13 feet. The big bird is now the second known large avian from the dinosaur era. The first to be identified was Gargantuavis philoinos, which lived in southern France around 70 million years ago. It too may have been flightless and ostrich-like.




Crocodile-Nosed Dinosaur Found in Australia   Live Science - June 15, 2011
A mysterious group of large, crocodile-snouted dinosaurs from the northern latitudes also inhabited the land that would become Australia, a newly found fossil reveals, indicating dinosaurs got around far more than is generally thought.




Australian dinosaur had UK double   BBC - June 15, 2011
A 5cm-wide (2in) fossil may have something big to say about how dinosaurs ranged across the Earth. The 125-million-year-old neck vertebra belonged to a spinosaurid - an animal with a crocodile-like snout that it probably used to prey on fish. The specimen is the first such dinosaur identified in Australia but one that is nearly identical to a UK creature. This suggests northern and southern hemisphere dinos had a lot more in common than previously thought.




How Dinosaurs Got So Huge   Live Science - April 13, 2011
Among dinosaurs, the biggest of the big is Argentinosaurus. This long-necked, puny-headed creature is a member of a group of giants called sauropods. This particular extinct creature measured as much as 140 feet (43 meters) long and weighed up to 90 tons (82 metric tons). Beyond inspiring awe, a creature of these proportions inspires all sorts of questions: Why and how did these dinosaurs, which started out relatively small, become so big? How did they feed and maintain their large bodies? A new exhibit at the American Museum of Natural History in New York City explores the mysteries surrounding their enormity.




  Dinosaur named 'thunder-thighs'   BBC - February 23, 2011
Scientists have named a new dinosaur species "thunder-thighs" because of the huge thigh muscles it would have had. Fossil remains recovered from a quarry in Utah, US, are fragmentary but enough to tell researchers the creature must have possessed extremely powerful legs. The new species, described in the journal Acta Palaeontologica Polonica, is a sauropod - the family of dinosaurs famous for their long necks and tails.




Fossil female pterosaur found with preserved egg   BBC - January 20, 2011
For fossil hunters, it represents one of those breakthrough moments. A pterosaur has been found in China beautifully preserved with an egg. The egg indicates this ancient flying reptile was a female, and that realisation has allowed researchers to sex these creatures for the first time.




Dino-era sex riddle solved by new fossil find   PhysOrg - January 20, 2011
The discovery of an ancient fossil, nicknamed 'Mrs T', has allowed scientists for the first time to sex pterodactyls – flying reptiles that lived alongside dinosaurs between 220-65 million years ago.




Meet 'Mrs. T': Ancient Flying Reptile Found with Egg   Live Science - January 20, 2011
As birdlike as the extinct winged reptiles known as pterosaurs might have seemed as they soared through prehistoric skies, it turns out their eggs and nests might have been like their more grounded lizard cousins than any feathered rival, scientists find. These insights, based on the fossils of a female pterosaur named "Mrs. T" and her egg, shed light on bygone creatures that once ruled the skies for more than 150 million years, whose home life we are only beginning to understand.




"Nasty" Little Predator From Dinosaur Dawn Found   National Geographic - January 14, 2011
Argentina (Pangea) - Valley of the Moon -- Deadly and dog-size, the dinosaur Eodromaeus (shown in reconstruction) lived in Argentina 230 million years ago, a new study says. The new species is providing fresh insight into the era before dinosaurs overtook other reptiles and ruled the world, a new fossil study says. (Watch video.) One of the earliest known dinosaurs, Eodromaeus was only about 4 feet (1.3 meters) long and would have barely reached the knees of an adult human. But this unassuming little dinosaur gave rise to the theropods, including Tyrannosaurus rex and the "terrible claw," Deinonychus, the new study suggests.




Dinosaur demise allowed mammals to 'go nuts'   BBC - November 26, 2010
Land mammals went from small "vermin" to giant beasts in just 25 million years, according to a new study. Mammals rapidly filled the "large animal" void left by the dinosaurs' demise 65 million years ago. They then went from creatures weighing between 3g and 15kg to a hugely diverse group including 17-tonne beasts.




Dino Demise Led to Evolutionary Explosion of Huge Mammals   Live Science - November 25, 2010
Mammals around the world exploded in size after the major extinction at the end of the Cretaceous period 65 million years ago, filling environmental niches left vacant by the loss of dinosaurs, according to a new study published Nov. 25 in the journal Science. The maximum size of mammals leveled off about 25 million years later, or 40 million years ago, because of external limits set by temperature and land area, reported an international team led by paleoecologist Felisa Smith of the University of New Mexico.




  Prehistoric winged beasts 'pole-vaulted' into flight   PhysOrg - November 16, 2010
Controversial claims that enormous prehistoric winged beasts could not fly have been refuted by the most comprehensive study to date which asserts that giant pterosaurs were skilled in flight.




Dinosaur the size of a giraffe could fly across continents   Telegraph.co.uk - November 15, 2010

Dr Mark Witton, a palaeontologist from the University of Portsmouth and Dr Michael Habib from Chatham University USA, have studied how the giant pterosaur, which was as big as a giraffe, could get off the ground. They found that the reptiles took off by using the powerful muscles of their legs and arms to push off from the ground, effectively pole-vaulting over their wings. Once airborne they could fly huge distances and even cross continents, the scientists claim. Dr Witton said: ''Most birds take off either by running to pick up speed and jumping into the air before flapping wildly, or if they're small enough, they may simply launch themselves into the air from a standstill.




Longest dinosaur thigh bone in Europe found in Spain   PhysOrg - September 24, 2010
Palaeontologists in Spain have found the fossiled thigh bone of a dinosaur that is almost two metres in length, the longest such femur ever discovered in Europe, they said Friday. The Dinopolis Foundation, a dinosaur research institute, said the 1.92-metre (6.3-feet) bone was found earlier this year at a site at Riodeva near Teruel in eastern Spain along with a 1.25-metre (4.1-feet) tibia and 15 vertebrae.




Really Horny Dinosaur Heralded from Lost Continent   Live Science - September 23, 2010




Fossils of new species of horned dinos found in Utah   BBC - September 23, 2010

Scientists have unearthed two new species of giant plant-eating horned dinosaurs in southern Utah, US. The creatures lived on the "lost continent" of Laramidia in the Late Cretaceous period, some 68 to 99 million years ago. Laramidia was formed when a shallow sea flooded part of what is now North America and divided the continent in two.




Humpback Dinosaur Surprises and Puzzles Experts   Live Science - September 11, 2010
A hunchback dinosaur of sorts once roamed what is now central Spain. The meat-eating beast sported a humplike structure low on its back, a feature never previously described in dinosaurs, and one that has scientists scratching their heads. The dinosaur, which is being called Concavenator corcovatus, measured nearly 20 feet (6 meters) in length and belonged to a group of some of the largest predatory dinosaurs known to walk the earth - carcharodontosaurs. It lived some 125 million years ago.




Double meteorite strike 'caused dinosaur extinction'   BBC - August 27, 2010
The dinosaurs were wiped out 65 million years ago by at least two meteorite impacts, rather than a single strike, a new study suggests. Previously, scientists had identified a huge impact crater in the Gulf of Mexico as the event that spelled doom for the dinosaurs. Now evidence for a second impact in the Ukraine has been uncovered.




Sauropods in Argentina kept their eggs warm near geothermal vents   PhysOrg - June 30, 2010
Researchers working in Argentina have found 100-million-year-old neosauropod nesting sites in which clutches of eggs were kept warm by geothermal vents.




Dinosaur mating rituals more elaborate than peacocks', scientists claim   Telegraph.co.uk - June 29, 2010
New research into pterosaurs and pelycosaurs - the fin-backed ancestors of modern mammals - have shown their elaborate headcrests and sails were developed for the purpose of sexual selection. Until now, many thought these appendages regulated body temperature or helped them steer while they were flying.




Dino-holocaust linked to monster storm   MSNBC - June 23, 2010
Scientists have revealed what may be the world's largest dinosaur graveyard.




Warm-Blooded Marine Reptiles at the Time of the Dinosaurs   Science Daily - June 16, 2010
Between 200 and 65 million years ago, fearsome marine reptiles reigned over the oceans. Were they warm-blooded like today's mammals and birds or cold-blooded like nowadays fish and reptiles? For the first time, a study has settled the debate: some large marine reptiles were warm-blooded (in other words, they were endothermic), giving them a considerable advantage to swim fast over long distances and to conquer cold regions.




Dinosaur-chewing mammals leave behind oldest known tooth marks   PhysOrg - June 16, 2010
Paleontologists have discovered the oldest mammalian tooth marks yet on the bones of ancient animals, including several large dinosaurs.




Dinosaur Had Horns the Size of Baseball Bats   Live Science - May 28, 2010

A tubby dinosaur sporting horns each the length of a baseball bat roamed what is now Mexico some 72 million years ago.




Rare 95 million-year-old flying reptile Aetodactylus halli is new genus, species of pterosaur   PhysOrg - April 27, 2010
A 95 million-year-old fossilized jaw discovered in Texas has been identified as a new genus and species of flying reptile, Aetodactylus halli.




Fossil find shows Velociraptor eating another dinosaur   BBC - April 6, 2010
Palaeontologists have uncovered fossil fragments of Velociraptor teeth alongside scarred bones of the large horned herbivore Protoceratops. The teeth of the predator match marks on the herbivore's bones, suggesting Velociraptor scavenged its carcass. The discovery is further evidence that predatory dinosaurs both hunted and scavenged their plant-eating relatives.




First tyrannosaur fossil from Southern Hemisphere Found - Tiny T. Rex Ancestors Achieved World Domination   National Geographic - March 26, 2010
The pint-size predator, found in what is now Victoria, Australia, is the first Tyrannosaurus rex ancestor unearthed in the Southern Hemisphere. Nicknamed the Southern Tyrant, the dinosaur lived during the early Cretaceous period, about 110 million years ago. Stretching just ten feet (three meters) and weighing only 175 pounds (80 kilograms), the animal, like T. rex, boasted a large head, short arms, and crushing jaws.




Utah: Fossil shows dinosaur caught in collapsing sand dune   BBC - March 24, 2010
Researchers have discovered a nearly complete fossil of a dinosaur which appears to have been caught in a collapsing sand dune. The Seitaad ruessi fossil, described in the journal PLoS One, is a relative of the long-necked sauropods that were once Earth's biggest animals. S. ruessi, found in what is now Utah, could have walked on all four legs, or risen up to walk on just two.




Volcanic eruption opened the door for dino rule   MSNBC - March 22, 2010
Some 200 million years ago, Earth was on the verge of either an age of dinosaurs or an age of crocodiles. It took the largest volcanic eruption in the solar system - and the loss of half of Earth's plant life - to tip the scales in the dinos' favor, say researchers.




Dinosaurs 'came to rule world after mass extinction'   PhysOrg - March 22, 2010
A shade more than 200 million years ago, the Earth looked far different than it does today. Most land on the planet was consolidated into one continent called Pangea. There was no Atlantic Ocean, and the rulers of the animal world were crurotarsans - creatures closely related to modern crocodiles.




How Dinosaurs Came to Rule the Earth   Live Science - March 22, 2010
More than 200 million years ago, as North Africa was ripping away from North America, opening up the Atlantic Ocean, hot lava poured out from Earth's surface. The lava, enough to more than cover the United States, created inhospitable conditions for most life ... except the dinosaurs. And new geologic discoveries suggest this climate catastrophe was the ticket for the dinosaur's rise to rule. At that time, about half of all species on Earth died out in what is called the end-Triassic extinction. Scientists have suggested massive volcanic eruptions could be to blame, spewing out lava and greenhouse gases such as carbon dioxide that would have totally changed the climate.




Mongolia: New Dinosaur: "Exquisite" Raptor Found   National Geographic - March 20, 2010

Like a zombie clawing its way out of the grave, a new dinosaur species was discovered when scientists spotted a hand bone protruding from a cliff in the Gobi desert of Inner Mongolia, paleontologists have announced. Called Linheraptor exquisitus, the new dinosaur is a raptor, a type of two-legged meat-eater, that lived during the late Cretaceous period in what is now northeastern China.

Dinosaur extinction link to crater confirmed   BBC - March 5, 2010
An international panel of experts has strongly endorsed evidence that a space impact was behind the mass extinction event that killed off the dinosaurs. They reached the consensus after conducting the most wide-ranging analysis yet of the evidence. Writing in Science journal, they rule out alternative theories such as large-scale volcanism.




Dinosaur's oldest relative found   BBC - March 4, 2010
Scientists have discovered a dinosaur-like creature 10 million years older than the earliest known dinosaurs. Asilisaurus kongwe is a newly discovered herbivore that lived during the middle Triassic period - about 245 million years ago. The scientists say that its age suggests that dinosaurs were also on the Earth earlier than previously thought.




Dinosaurs Ten Million Years Older Than Thought   National Geographic - March 3, 2010
A new dinosaur relative found in Tanzania is the oldest known creature of its kind - a discovery that pushes back the origin of dinosaurs by at least ten million years, paleontologists say. Dubbed Asilisaurus kongwe, the Labrador retriever-size creature was a silesaur, the closest relatives to true dinosaurs. The newfound animal lived 243 million years ago, during the middle Triassic period.




Dinosaurs Had Wrists Like Birds   Live Science - March 2, 2010
The flexible wrists of birds that let them fold their wings have now been seen in dinosaurs well before flight, scientists find. Dinosaurs such as Velociraptor might have partly folded their feathered arms to protect such plumage from harm's way, researchers explained. The wrists and the feathers in the lineage that led to birds then became more extreme, laying the groundwork for flight, they added.

Feathered Dinosaurs Leapt from Trees, Not the Ground   Live Science - January 25, 2010
Whether birds first evolved flight as ground dwellers or took to the skies from trees has been a longstanding debate. A new study of an ancient four-legged creature called Microraptor gui, poised on the boundary between dinosaurs and birds, suggests that the arboreal, or tree-living, idea may be correct. Microraptor lived about 120 million years ago, and is thought to be an early ancestor of modern birds. It had bird-like feathers that appear to have been used for flight, but a dinosaur-like head with sharp teeth and scales.




New T. Rex Cousin Suggests Dinosaurs Arose in S. America   National Geographic - December 10, 2009
The discovery of a dog-size T. rex ancestor may rewrite dinosaur evolutionary history, a new study says. Measuring about 6 feet (180 centimeters) long--tail included--the 215-million-year-old Tawa hallae was found by hikers who noticed some small bits of bone at New Mexico's fossil-rich Ghost Ranch. The dinosaur bears a mix of characteristics, such as air sacs, that link Tawa to older dinosaur species found in South America, researchers say.

Study: T. rex teens fought, disfigured each other   MSNBC - November 2, 2009
Tyrannosaurus rex's reputation as a fierce, battle-hungry carnivore can now also apply to teenagers of this Late Cretaceous dinosaur, according to a new study. The evidence comes from "Jane," who died when she was just a T. rex teen. Her fossils, found at Montana's Hell Creek Formation in 2001, reveal that another T. rex teenager severely bit her in the head, breaking her snout to the point of disfigurement.




Montana: New Dinosaur Built Like a Sherman Tank   Live Science - October 30, 2009
Now called Tatankacephalus cooneyorum, the beast is a type of ankylosaur, or a group of plant-eating dinosaurs that resembled nature's armored tanks as they walked about on four limbs and their bodies were covered with bony armor that may have been covered with a colorful keratinous sheathing (same as the stuff in bird beaks and turtle shells).

What Do Dinosaurs And The Maya Have In Common?   Science Daily - September 14, 2009
One of the world's most famous asteroid craters, the Chicxulub crater, has been the subject of research for about twenty years. The asteroid impact that formed it probably put an end to the dinosaurs and helped mammals to flourish. Together with an Anglo-American team, an ETH Zurich researcher has studied the most recent deposits that filled the crater. The results provide accurate dating of the limestones and a valuable basis for archaeologists to research the Maya.




Australia discovers new dinosaur   BBC - August 27, 2009

Tyrannosaurus rex 'picked on baby dinosaurs and ate them whole'   National Geographic - August 7, 2009
Although past research has suggested Tyrannosaurus rex was related to chickens, now findings hint this giant predator might have acted chicken too. Instead of picking on dinosaurs its own size, researchers now suggest T. rex was a baby killer that liked to swallow defenseless prey whole. Fossil evidence of attacks of tyrannosaurs or similar gargantuan "theropods" on triceratops and duck-billed dinosaurs has been uncovered before, conjuring images of titanic clashes.

New dinosaur gives bird wing clue   BBC - June 17, 2009
A new dinosaur unearthed in western China has shed light on the evolution from dinosaur hands to the wing bones in today's birds. The fossil, from about 160 million years ago, has been named Limusaurus inextricabilis. The find contributes to a debate over how an ancestral hand with five digits evolved to one with three in birds.




Fossil Fingers Solve Bird Wing Mystery?   National Geographic - June 17, 2009

The fossil hand of a long-necked, ostrich-like dinosaur recently found in China may help solve the mystery of how bird wings evolved from dinosaur limbs, according to a new study. The ancient digits belonged to a 159-million-year-old theropod dinosaur dubbed Limusaurus inextricabilis. Theropods are two-legged dinos thought to have given rise to modern birds.




Giant Dinosaurs Stuck Their Necks Out, Not Up?   National Geographic - May 15, 2009
Long-necked dinosaurs didn't graze treetops, according to new research that suggests the prehistoric animals were better off holding their necks horizontal, not upright. Lifting long necks at steep angles would have put intense pressure on sauropod hearts, requiring dramatic expenditures of energy to keep blood pumping to the brain, a new study of dinosaur circulation says.

Canadian dig yields tiny dinosaur   BBC - March 17, 2009
The smallest meat-eating dinosaur yet to be found in North America has been identified from six tiny pelvic bones. Hesperonychus was the size of a small chicken, and used its rows of serrated teeth to feed on insects, experts say. The bird-like creature is closely related to Microraptor - a tiny feathered dinosaur discovered in China. The specimen helps to confirm that reptiles, and not mammals, filled the role of small predators during the age of the dinosaurs. The fossil skeleton, which lay misidentified for 25 years as a lizard, belongs to a group of dinosaurs called the theropods - bipedal reptiles that eventually gave rise to birds.




  Young dinosaurs roamed together, died together   PhysOrg - March 16, 2009

Pterosaurs Took Flight on All Fours   National Geographic - January 7, 2009
Pterosaurs took flight using all fours, a discovery that flies in the face of previous research on the ancient reptiles, a new study says. Two of the giant creatures' "legs" were extremely strong wings, which when folded, created "knuckles" that allowed the animals to walk and jump (above left, the pterosaur known as Hatzegotpteryx in an artist's rendering). The way a bird lifts off using two legs doesn't make sense for pterosaurs, which would have had to heave their 500 pounds (227 kilograms) airborne using only their hind legs, the study says.

Dinosaur Killer May Have Been Volcanism, Not Asteroid    Live Science - December 15, 2008
Scientists have found even more evidence that volcanism, not a space rock, may be the culprit behind the dinosaurs' demise. The first well-supported theory for what wiped out all large dinosaurs involved a space rock that created the Chicxulub crater in Mexico’s Yucatan Peninsula. But climate change and volcanism have been suggested in recent decades, too. A set of new studies further shifts the blame away from the impact and toward volcanism, a position that geologist Gerta Keller of Princeton University has taken in recent years.




Bird-like dinosaur sat on eggs   National Geographic - November 13, 2008
If it looks like a duck-billed dinosaur nest, it's probably from a duck-bill - unless it's a newly identified clutch of fossilized eggs from a private collection in Calgary, Canada. The eggs, originally found in Montana in the 1990s, actually belong to a carnivorous dinosaur - either a creature related to the fearsome velociraptor (seen above, top right) or a birdlike, upright-walking dinosaur called a caenganathid (top left), a new study says.

Yeah, it's cliche to say Tyrannosaurus rex was deadly. But the tyrant king was likely true to the billing. Its bone-crushing jaws could splinter prey like toothpicks, after all. And the beast was big, up to 40 feet long, 20 feet tall, and may have topped the scales at nearly 16,000 pounds.




New feathered dinosaur discovered BBC - October 23, 2008




The fossil of a "bizarre" feathered dinosaur from the era before birds evolved has been discovered in China. Epidexipteryx was very bird-like, with four long ribbon-like tail feathers - probably used in display. But the pigeon-sized creature shows no sign of the flight feathers seen in other bird-like dinosaurs




First Dinosaur Feathers for Show, Not Flight? National Geographic - October 22, 2008
One of the oldest known dinosaur relatives of birds had "bizarre" anatomy, including long, ribbon-like tail feathers that suggest plumage may have first evolved for show rather than for flight, scientists say. Farmers unearthed a fossil of the new dino species, dubbed Epidexipteryx hui, from the hills of Inner Mongolia in late 2007.




Study Of Polar Dinosaur Migration Questions Whether Dinosaurs Were Truly The First Great Migrators Science Daily - October 22, 2008
Contrary to popular belief, polar dinosaurs may not have traveled nearly as far as originally thought when making their bi-annual migration. The idea that these animals may have travelled distances nine times further than mule deer or four times those of wildebeest would have made them the greatest migrators in history. "There are strong opinions regarding dinosaur migration, but we decided to take a different approach, looking at variables such as energy requirements," said Bell. Their research led them to suggest that migrating dinosaurs could have travelled up to 3,000 kilometres in a round trip lasting perhaps up to six months half of the distance suggested previously.




Utah: Dinosaur Graveyard Yields Fossil Bounty Live Science - October 21, 2008
A "dinosaur graveyard" full of fossils has been discovered in a former river bed in Utah, presenting an opportunity for a decade's worth of Jurassic research by paleontologists, it was announced this week. Scientists and technicians with the Utah Thornbury Dinosaur Expedition unearthed an abundance of sauropod (an herbivorous long-necked dinosaur) finds, as well as the bones of several carnivorous dinosaurs, said paleontologist Luis Chiappe, director of the Natural History Museum of Los Angeles County’s Dinosaur Institute. Nearby, the team, led by the museum, also discovered a 5-foot humerus (arm) bone from a brachiosaur, a gigantic long-necked dinosaur.




Amazing collection of dinosaur footprints on the Arizona-Utah border in the US BBC - October 20, 2008
Scientists have identified an amazing collection of dinosaur footprints on the Arizona-Utah border in the US. There are so many prints - more than 1,000 - that geologists have dubbed the site "a dinosaur dance floor". Located within the Vermilion Cliffs National Monument, the marks were long thought simply to be potholes gouged out of the rock by years of erosion. A paper describing the 190-million-year-old footprints is published in the palaeontology journal Palaios.




New Dinosaur May Link S. American, Aussie Dinos National Geographic - June 11, 2008
A rare fossil found in Australia suggests dinosaurs were able to traverse the vast prehistoric continent of Gondwana much later than thought, scientists report. The hundred-million-year-old fossil belonged to a two-legged meat-eater, or theropod, that is closely related to Megaraptor namunhuaiquii, a giant, big-clawed carnivore from Argentina, says a team led by Nathan Smith of the University of Chicago's Field Museum.




First Dinosaur Tracks Found on Arabian Peninsula National Geographic - May 20, 2008

More than a hundred dinosaur footprints have been found on the Arabian Peninsula, the first time that tracks have been unearthed in the region, a new study says. The 150-million-year-old tracks were made by ornithopods and sauropods large two- and four-legged plant-eaters, respectively in modern-day Yemen.




When Did Dinosaurs Go Extinct? Cretaceous-Tertiary Boundary Dating Refined Science Daily - April 28, 2008
Scientists at the University of California, Berkeley, and the Berkeley Geochronology Center have pinpointed the date of the dinosaurs' extinction more precisely than ever thanks to refinements to a common technique for dating rocks and fossils. The argon-argon dating method has been widely used to determine the age of rocks, whether they're thousands or billions of years old. Nevertheless, the technique had systematic errors that produced dates with uncertainties of about 2.5 percent.




T. Rex Protein "Confirms" Bird-Dinosaur Link National Geographic - April 24, 2008
A new study of ancient proteins retrieved from a Tyranosaurus rex fossil confirms the long-hypothesized evolutionary connection between dinosaurs and modern birds, experts say. The finding is the first molecular evidence that birds, not lizards or other reptiles, are the closest living relatives of dinosaurs, the researchers note. A close relationship between the two groups was already widely suspected, based on similarities in skeletal features. The new research follows a breakthrough study last year in which scientists reported the recovery and partial molecular sequencing of T. rex and mastodon proteins.




Hundreds of Dino-Era Animals in Amber Revealed by X-Ray National Geographic - April 4, 2008
A hidden trove of fossilized treasures in cloudy ancient tree sap have been brought to light with a new form of "x ray vision," scientists announced recently. Fossilized tree sap, or amber, is usually transparent but can become murky due to contamination by dirt and other debris.




Secret 'dino bugs' revealed BBC - April 1, 2008

A hidden trove of fossilized treasures in cloudy ancient tree sap have been brought to light with a new form of "x ray vision," scientists announced recently. Fossilized tree sap, or amber, is usually transparent but can become murky due to contamination by dirt and other debris. The dirtiest type, called opaque amber, resembles rocks and is a challenge for paleontologists who want to see organisms trapped inside. That is changing with synchrotron imaging, which uses high-energy x-rays generated by accelerated electrons to examine hidden fossils.




New "Sea Monster" Species Identified National Geographic - March 27, 2008

The remarkably well-preserved fossil of a dinosaur-era sea creature found in a Canadian mine is turning out to be a gold mine for paleontologists. The Cretaceous-period reptile, dubbed Nichollsia borealis, is not only a new species - it represents a whole new genus, scientists announced on March 20. It's also one of the oldest and most complete plesiosaur fossils ever unearthed in North America. Plesiosaurs were carnivorous reptiles that roamed the seas between about 205 million to 65 million years ago. Mine workers found the intact creature about 200 feet (60 meters) deep in a surface mine in Alberta in 1994. The Syncrude company extracts oil from the mine's sandy soil. A "tomb" of sandstone preserved the 8.5-foot-long (2.6-meter-long) creature almost perfectly—unlike other plesiosaur fossils that are often found in porous shale.




North Dakota: Workers Uncovering Mummified Dinosaur National Geographic - March 19, 2008
Using tiny brushes and chisels, workers picking at a big greenish-black rock in the basement of North Dakota's state museum are meticulously uncovering something amazing: a nearly complete dinosaur, skin and all.

Dino-Era Feathers Found Encased in Amber National Geographic - March 11, 2008

Seven dino-era feathers found perfectly preserved in amber in western France highlight a crucial stage in feather evolution, scientists report. The hundred-million-year-old plumage has features of both feather-like fibers found with some two-legged dinosaurs known as theropods and of modern bird feathers, the researchers said. This means the fossils could fill a key gap in the puzzle of how dinosaurs gave rise to birds, according to a team led by Vincent Perrichot of the Museum fur Naturkunde-Berlin in Germany. The find provides a clear example "of the passage between primitive filamentous down and a modern feather," said team member Didier Neraudeau of the University of Rennes in France. The study team isn't sure yet whether the feathers belonged to a dino or a bird. But fossil teeth from two dino families thought to have been feathered were excavated from rocks just above the layer that contained the amber, Perrichot said.




New Dinos May Have Killed Like Sharks, Ate Like Hyenas National Geographic - February 13, 2008
Two 110-million-year-old fossils of meat-eating dinosaurs that once ruled the southern continents have been found in Africa, scientists announced. First discovered in 2000, the new species are theropodstwo-legged carnivores that lived in the same habitat and grew to about 25 feet (7.6 meters) long. Eocarcharia dinops, or "fierce-eyed dawn shark," was likely an ambush predator armed with massive, shark-like teeth. Kryptops palaios, or "old hidden face," is thought have been a hyena-like scavenger that feasted on carcasses.




Bizarre New Dinosaurs Found in Sahara National Geographic - February 13, 2008
Face-to-face in a new fossil discovery, two newfound dinosaur species were revealed today. Both roamed Africa's Sahara desert some 110 million years ago and were found in present-day Niger. dawn shark,'' (left) was armed with three-inch (7.6-centimeter), blade-like teeth, likely for disabling and dismembering prey. Some experts speculate that its menacing brow was used in head-butting contests with rival males. Kryptops palaois, or ''old hidden face,'' boasted a horny face that may have had a special role.




Giant Duck-Billed Dino Discovered in Mexico National Geographic - February 13, 2008
A giant new species of crested duck-billed dinosaur has been unearthed in Mexico, researchers say. The discovery of the 72-million-year-old fossil adds to the rich gallery of dinosaurs that scientists now know lived in western North America during the latter part of the dinosaur era. The new species was dubbed Velafrons coahuilensis in honor of the state of Coahuila in north-central Mexico where the fossil was found. Reaching lengths up to 35 feet (10.5 meters) long, the newfound dino was a plant-eater belonging to a group of duck-billed dinosaurs, or hadrosaurs, that roamed the region together with carnivores like tyrannosaurs and velociraptors.




China: New Mini-Pterodactyl Among Smallest Known National Geographic - February 11, 2008

A new species of miniature flying reptile that lived more than 120 million years ago has been unearthed in China. The mini-pterosaur, dubbed Nemicolopterus crypticus, had a wingspan of only 10 inches (25 centimeters) about the size of a modern sparrow.




"Amazing" Dino Fossil Found With Skin, Tissue in China National Geographic - January 16, 2008
The fossil of a dinosaur with a flesh wound has been discovered in northeastern China, offering the most complete view to date of dinosaur skin, a scientist says. The fossil is of a 130-million-year-old Psittacosaurus, or parrot lizard, a beaked reptile about the size of a pig that could walk on either two or four legs.




Big Dinosaurs Had "Teen Sex" National Geographic - January 14, 2008
Big dinosaurs, like humans, reached sexual maturity during the messy growth spurts of adolescence, according to a new study. The reproductive strategy of dinosaurs was unlike that of their reptilian ancestors or their bird descendants, the study concludes.




Dinosaur Had Crocodile-Like Skull National Geographic - January 14, 2008
This bizarre British dinosaur may look like a meat-eater, but its skull actually functioned more like that of a fish-eating crocodile, a new study has found. When eating, Baryonyx walkeri's skull stretched and bent in a similar fashion to the modern-day gavial, or gharial, an Indian crocodile with long, narrow jaws. This spinosaur - part of a family of dinosaurs called "spine lizards," which lived about 125 million years ago also had large, 12-inch-long (30-centimeter-long) front claws. The 30-foot-long (9-meter-long) animal may have used them for scooping fish from the water.




New Dinosaur Discovered in Antarctica Live Science - December 11, 2007
A hefty, long-necked dinosaur that lumbered across the Antarctic before meeting its demise 190 million years ago has been identified and named, more than a decade after intrepid paleontologists sawed and chiseled the remains of the primitive plant-eater from its icy grave. They found a partial foot, leg and ankle bones on Mt. Kirkpatrick near the Beardmore Glacier in Antarctica at an elevation of more than 13,000 feet (nearly 4,000 meters). It wasn't until recently, though, that researchers examined the fossils.




Massive Dinosaur "Graveyard" Discovered in Spain National Geographic - December 10, 2007
A spectacular dinosaur "graveyard" containing thousands of fossils has been discovered in eastern Spain, scientists say. Eight different dinosaur species, including several kinds of armor-clad plant-eaters that were among the world's largest types of dino, have been identified among the 8,000 fossils found to date, according to experts excavating the site. The 70-million-year-old fossils show a stunning array of dinosaur diversity for a period that is very poorly known in Western Europe, said paleontologist José Luis Sanz of Autonomous University in Madrid.




North Dakota: Amazing find of dinosaur 'mummy' BBC - December 3, 2007
Fossil hunters have uncovered the remains of a dinosaur that has much of its soft tissue still intact. Skin, muscle, tendons and other tissue that rarely survive fossilization have all been preserved in the specimen unearthed in North Dakota, US. The 67 million-year-old dinosaur is one of the duck-billed hadrosaur group. The preservation allowed scientists to estimate that it was more muscular than thought, perhaps giving it the ability to outrun predators like T. rex. The researchers propose that the dinosaur's rump was 25% larger than had previously been thought. This probably meant more muscle mass and therefore greater acceleration, giving it a greater chance of evading meat-eating dinosaurs in hot pursuit.




Bizarre Dinosaur Grazed Like a Cow, Study Says National Geographic - November 15, 2007
A weird-looking dinosaur with a muzzle resembling a vacuum cleaner suggests long-necked plant-eaters such as the well-known Diplodocus didn't always have their heads in the trees. The findings are based on fossil analyses of a 110-million-year-old dinosaur found in the Sahara region of Africa.




Dino With "Vacuum Mouth" Revealed National Geographic - November 15, 2007

This bizarre-looking dinosaur "mowed" through ground vegetation using its vacuum cleaner-shaped mouth more than a hundred million years ago, a new study has found.




Fossil is new family of dinosaur BBC - November 15, 2007

A fossilised bone dug up near Hastings 113 years ago has been recognised as a completely new family of dinosaur. The animal belongs to a general type of dinosaur called a sauropod - which was characterised by a large body, a long neck and a small head. A PhD student from the University of Portsmouth stumbled upon the specimen while browsing through the shelves of London's Natural History Museum. The fossil represents the dorsal vertebra (back bone) of a new family, genus and species of dinosaur now named Xenoposeidon proneneukus. It lived about 140 million years ago, was about the size of an elephant and weighed 7.5 tonnes.




Polar Dinosaurs Left Their Tracks Live Science - October 19, 2007
Newly discovered footprints made by carnivorous dinosaurs in Australia reveal the ancient beasts survived in polar climes when the outback was still joined to Antarctica and close to the South Pole. The discovery of the three fossil tracks, each about 14 inches (36 centimeters) long and showing two to three partial toe-prints, was presented by Anthony Martin, senior lecturer in environmental studies at Emory University, today at a meeting of the Society of Vertebrate Paleontology in Austin, Texas. The researchers estimate the tracks were made 115 million years ago during the Cretaceous Period by theropod dinosaurs, a group of bipedal carnivores that includes Tyrannosaurus rex. And based on the tracks' size, Martin and his colleagues estimate the beasts stood 4.6 to 4.9 feet (1.4 to 1.5 meters) at the hip. While not half-pints, the dinosaurs would've been about 20 percent smaller than Allosaurus, a large theropod from the Jurassic Period.




'Giant dino' found in Patagonia (Argentina) BBC - October 16, 2007
Scientists think they have found a new species of giant plant-eating dinosaur, Futalognkosaurus dukei, that roamed the Earth some 80m years ago. It would have measured at least 32m (105ft) in length, making it one of the biggest dinosaurs ever found, Argentine and Brazilian paleontologists say. The skeleton showed signs that its owner had been eaten by predators. The excavation site in Argentina has yielded a series of specimens since the first fossils were found there in 2000. <




Giant Dino Found in Fossil Argentina National Geographic - October 16, 2007

An artist's rendering depicts a newly discovered giant dinosaur (left and second from left) lumbering through its habitat some 80 million years ago. The skeleton of what is believed to be a new dinosaur species - a 105-foot (32-meter) plant-eater that is among the largest dinosaurs ever found has been uncovered. Scientists from Argentina and Brazil said the Patagonian dinosaur appears to represent a previously unknown species of Titanosaur because of the unique structure of its neck. This is one of the biggest in the world and one of the most complete of these giants that exist.




Big Waddling Dinosaur Discovered Live Science - October 4, 2007
A strange, long-necked waddling dinosaur with massive arms and probably enormous claws has been discovered. It walked only on its hind legs like the carnivorous dinosaurs from which it evolved, but Suzhousaurus megatherioides, meaning "giant sloth-like reptile from Suzhou," was an herbivore, says researcher Daqing Li of the Third Geology and Mineral Resources Exploration Academy of Gansu Province in northwestern China, where the fossil specimen was found.




"Missing Link" Dinosaur Discovered in Montana National Geographic - October 3, 2007

An unusual new species of dinosaur discovered in a Montana fossil provides a long-sought link between a primitive group of dinos in Asia and those that roamed North America, experts say. The newfound species is a very early form of ceratopsian, whose descendants are best known for their fearsome horns and flashy neck frills. An unusual new species of dinosaur discovered in a Montana fossil provides a long-sought link between a primitive group of dinos in Asia and those that roamed North America, experts say. The newfound species is a very early form of ceratopsian, whose descendants are best known for their fearsome horns and flashy neck frills.




Utah: Duck-billed dinosaur had big bite BBC - October 3, 2007

The Gryposaurus, discovered in southern Utah, had a distinct duck-like bill and a powerful, strengthened jaw. The two-legged creature, was more than 10m (30ft) long. Analysis suggests that the dinosaur, which lived in the Cretaceous forests of North America about 65-80 million years ago, was a successful herbivore.




Bug Warfare Discovered in Dinosaur Era Live Science - September 4, 2007
The discovery of a bug that roamed with the dinosaurs has shown that insects were equipped with chemical weapons much earlier than thought.




Dinosaurs Had Sex As Youths, Study Says Live Science - July 20, 2007
Birdlike dinosaurs did not wait until they were fully grown to start having sex, a new study says. Early sexual maturity is a trait associated with modern-day crocodiles more than birds a surprise because most scientists believe birds are akin to modern dinosaurs.




Dinosaur Fossils Part of Longtime Chinese Tonic National Geographic - July 16, 2007
When Chinese villagers were recently discovered grinding dinosaur fossils into traditional elixirs, the incident was reported worldwide as a time-bending oddity of modern-day China. Yet such fossils have probably been key ingredients in Chinese "dragon bone" medicines for the past 25 centuries.




Meep-Meep! 'Road Runner' Dino Discovered Live Science - June 23, 2007
Skeletal remains from a 220-million-year-old dinosaur reveal a prehistoric road runner of sorts, whose svelte figure and long legs allowed it to evade predators lickety-split. The creature stood about 12 inches tall at the hips and weighed just 4.4 pounds. Its head-to-tail length was about 3 feet, with about half of that taken by the tail. The new species is aptly named Eocursor parvus, meaning early little runner. The fox-sized dinosaur is thought to be one of the oldest members of a group of plant-eating dinos called Ornithischians. Later Ornithischians, including the “elephantine” Stegosaurus and Triceratops, evolved from this half-pint, two-legged dinosaur.




Dinosaur Extinction Spurred Rise of Modern Mammals, Study Says National Geographic - June 20, 2007
The asteroid that finished off the dinosaurs 65 million years ago opened up niches for the majority of today's living mammals, according to a new study. The finding is the latest volley in a long-simmering debate over when and where the direct ancestors of everything from whales to rats to humans first arose.




Massive Birdlike Dinosaur Unearthed in China National Geographic- June 13, 2007
The remains of a huge beaked dinosaur with the looks of an ostrich but the weight of a rhino have been discovered in China's Gobi desert, fossil hunters have announced. The previously unknown dinosaur weighed in around 1.5 tons (1.4 metric tons) and stood more than 16 feet (5 meters) tall - an extraordinary size given its birdlike appearance, say the Chinese researchers who found it.




Prehistoric Gliding Lizard Discovered in U.S. National Geographic - June 13, 2007
Two hundred and twenty million years ago long-necked lizards spread their ribs and glided on winglike membranes through North American forests, according to a new discovery. Two fossils of the animal, called Mecistotrachelos apeoros ("soaring, long-necked"), were excavated at a quarry on the Virginia-North Carolina state border.




Fossil traces deep dinosaur roots - about 210 million years ago BBC - June 13, 2007
Scientists have described a new primitive dinosaur species, Eocursor parvus, which lived in the Late Triassic - about 210 million years ago.




Big Dinosaurs Could Hear Only Low-Pitched Sounds, Experts Suggest National Geographic - June 8, 2007
Large dinosaurs' hearing was more sensitive to booms and thuds than squeaks and whistles, new research says. Dinos such as Brachiosaurus and Allosaurus probably could hear the deep-toned sounds of other dinosaurs' footfalls from miles away, researchers say.




T. rex was 'slow-turning plodder' BBC - June 5, 2007
A Tyrannosaurus rex would have had great difficulty getting its jaws on fast, agile prey, a study confirms. A US team has used detailed computer models to work out the weight of a typical "king of the dinosaurs", and determine how it ran and turned. The results indicate a 6 to 8-tonne T. rex was unlikely to have topped 40km/h (25mph) and would take a couple of seconds to swivel 45 degrees.




"Feathered" Dinosaur Was Bald, Not Bird Ancestor, Controversial Study Says National Geographic - June 2, 2007
A shadow of doubt has been thrown over the widely held theory that dinosaurs had feathers and that they gave rise to modern birds. In a new study, researchers examined the fossil of a 140-million-year-old turkey-size dinosaur called Sinosauropteryx.




T. Rex, Other Big Dinosaurs Could Swim, New Evidence Suggests National Geographic - May 29, 2007
Predatory dinosaurs such as the mighty Tyrannosaurus rex could swim, say scientists who claim they have found definitive proof of the behavior. The evidence, they say, is odd scuff marks found in Cretaceous-era rock in northern Spain's Cameros Basin.




Protein links T. rex to chickens BBC - April 12, 2007
Protein extracted from 68 million-year-old T. rex bones has shed new light on the evolutionary link between dinosaurs and birds. Researchers compared organic molecules preserved in the T. rex fossils with those of living animals, and found they were similar to chicken protein. The discovery of protein in dinosaur bones is a surprise - organic material was not thought to survive this long.




Fossil reveals a caring, sharing dinosaur Guardian - March 21, 2007
The monstrous image of the dinosaurs needs a more touchy-feely makeover after US researchers found convincing evidence that at least some of the king reptiles cared for their young and even dug burrows to hide from predators. The find in Montana includes fossilized bones of an adult and two young. "Here we have the burrow, den, an adult with traits for digging, and two juveniles, all in the same place," said Anthony Martin at Emory University, Atlanta. "It doesn't get much better than that."




Dinosaur den diggers discovered BBC - March 21, 2007
The fossil remains of small dinosaurs that burrowed into the ground have been found by scientists in Montana, US.




Triceratops' "Granddaddy" Discovered in Canada National Geographic - March 6, 2007
Its forehead sprouted horns as large as human arms, and its skull was frilled with spikes the size of sharks' teeth. Even to the scientists who discovered this new species of dinosaur, the fearsome-looking creature was a bizarre sight. But its weird appearance is what helped experts peg the dino as a missing link, a never-before-seen member from the family tree of Triceratops. Dubbed Albertaceratops nesmoi, the 78-million-year-old dinosaur was unearthed in 2001 by paleontologist Michel Ryan and a colleague in the badlands of southern Alberta, Canada.




Over 100 Dinosaur Eggs Found in India National Geographic - February 6, 2007

Three Indian explorers are giving amateurs a good name. The fossil enthusiasts recently set out on an 18-hour hunt near the central city of Indore and ended up with more than a hundred dinosaur eggs. They are the typical, spherical eggs that researchers interpret as having been laid by sauropod dinosaurs," paleontologist Hans-Dieter Sues told National Geographic News via email after viewing photos of the find. Sues is an associate director for research and collections at the National Museum of Natural History in Washington, D.C., and a former member of the National Geographic Society's Committee for Research and Exploration.




Two-headed reptile fossil found BBC - December 20, 2006

Scientists have found what is thought to be the first example of a two-headed reptile in the fossil record. The abnormal animal, belonging to a group of aquatic reptiles, was unearthed in northeastern China and dates to the time of the dinosaurs. The specimen reveals that it must have been very young when it died and became fossilised, says lead researcher Eric Buffetaut.




Europe's "Biggest Dino" Discovered in Spain National Geographic - December 21, 2006

A massive Jurassic-age dinosaur - the largest ever discovered in Europe has been unearthed by Spanish fossil hunters. The new species, Turiasaurus riodevensis, measured up to 120 feet (37 meters) in length and weighed as much as 48 tons - equivalent to the weight of seven adult male elephants - the researchers say. The 150-million-year-old dinosaur is thought to represent a new type of sauropod, the group of long-necked plant-eaters with huge tails that were the largest animals ever to have walked Earth.




Baby plesiosaur bones found in Antarctic China View - December 13, 2006

he bones of a baby plesiosaur have been recovered from an Antarctic island, scientists reported Monday. In life, 70 million years ago, the five-foot-long animal would have resembled Nessie, the long-necked creature reported to inhabit Scotland's Loch Ness.




Giant Dinosaur Found in Argentina National Geographic - July 28, 2006
Argentinean scientists have discovered gigantic neck, back, and tail bones from one of the biggest dinosaurs ever to roam the Earth. Puertasaurus reuili, seen here in an artist's conception, is estimated to have been 115 to 131 feet (35 to 40 meters) long and weighed between 88 and 110 tons (80 and 100 metric tons).




T. rex struggled with midlife crisis MSNBC - July 14, 2006
A major midlife crisis came early for dinosaurs in the tyrannosaur family, as new research suggests many of the giant beasts died just as they reached their sexual prime. Like modern long-living birds and mammals, Tyrannosaurus rex and other tyrannosaur species experienced high mortality rates as infants and young adults, with just a choice few surviving to maturity. Researchers recently investigated a quarry in the Canadian province of Alberta, where in 1910 several fossilized specimens were found of the species Albertosaurus sarcophagus, a member of the tyrannosaur family. The collection of 22 dinos, which range from 6 to 30 feet long (2 to 9 meters long), remains the best evidence that tyrannosaurs were gregarious animals living in packs




For Tyrannosaurs, Teen Years Were Murder National Geographic - July 14, 2006
If they survived the deadly toddler years, tyrannosaurs apparently had it pretty cushy, at least until they hit dinosaur puberty. But after these dinosaurs reached sexual maturity, life's harsher realities kicked in again. Beginning at about age 14, tyrannosaurs suffered death rates of nearly 23 percent a year, according to a new study.




Bigger dinosaurs had warmer blood BBC - July 11, 2006
The bigger a dinosaur was, the warmer its blood, a study of the big beasts' fossil remains suggests. Dinosaurs were long considered to be cold-blooded reptiles. More recently, some researchers have proposed that the extinct creatures actively regulated their body temperature like mammals. A study in the journal Plos Biology now suggests this is not the case, but that bigger dinosaurs may have lost heat so slowly that they stayed warm anyway.




Dinosaur-Era Birds Surprisingly Ducklike, Fossils Suggest National Geographic - June 15, 2006

A new species of mini-dinosaur has been unearthed in northern Germany BBC - June 7, 2006
A new species of mini-dinosaur has been unearthed in northern Germany. The creature was of the sauropod type - that group of long-necked, four-footed herbivores that were the largest of all the dinosaurs. But at just a few metres in length, this animal was considerably smaller than its huge cousins, scientists report in the journal Nature. The team thinks the Jurassic species evolved its small form in response to limited food resources on an island.




North Sea fossil is deepest dino BBC - April 27, 2006
The first dinosaur fossil discovered in Norway is also the deepest one that has been found anywhere in the world.




Norway: The World's Deepest Dinosaur Finding - 2,256 Metres Below The Seabed Science Daily - April 25, 2006
The somewhat rough uncovering of Norway's first dinosaur happened in the North Sea, at an entire 2256 metres below the seabed. It had been there for nearly 200 million years, ever since the time the North Sea wasn't a sea at all, but an enormous alluvial plane. It is merely a coincidence that the remains of the old dinosaur now see the light of day again, or more precisely, parts of the dinosaur. The fossil is in fact just a crushed knucklebone in a drilling core -- a long cylinder of rock drilled out from an exploration well at the Snorre offshore field.




Meat-Eating Dinosaur Was Bigger Than T. Rex National Geographic - April 18, 2006
The newly revealed species is one of the biggest carnivores ever to have walked the Earth, dinosaur experts say.




T. Rex's Oldest Ancestor Discovered in China National Geographic - February 8, 2006
The earliest in a line of dinosaurs that gave rise to Tyrannosaurus rex has been discovered in China. Scientists say the 160-million-year-old animal, which had an elaborate head crest and possibly bore simple feathers, is the oldest known tyrannosaur - a group of swift, flesh-eating dinos that culminated in T. rex some 90 million years later.




Crocodile ancestor found in museum basement National Geographic - January 25, 2006

A study of fossil dinosaur dung has for the first time confirmed that the ancient reptiles ate grass BBC - November 17, 2005
A study of fossil dinosaur dung has for the first time confirmed that the ancient reptiles ate grass. Grass was previously thought to have become common only after the dinosaurs died out 65 million years ago. But grasses were probably not a very important part of dinosaur diets - the fossilized feces show the big beasts ate many different types of plants.




Remains of 'Godzilla' croc found in Argentina BBC - November 11, 2005
The fossilized remains of a crocodile that ruled the oceans 140 million years ago have been discovered in Patagonia. Scientists have nicknamed the creature Godzilla, because of its dinosaur-like snout and jagged teeth. The US-Argentine team of researchers believes the animal was a ferocious predator, feeding on other marine reptiles and large sea creatures.




China: Ancient Flying Reptiles Discovered National Geographic - October 5, 2005
Fossils found in northeastern China have revealed two new species of flying reptiles that lived more than 120 million years ago, during the dinosaur era. The extinct species, known as pterosaurs, belong to groups previously found only in Europe. Scientists made the find in a region known for the diversity of its fossil specimens dating from the Cretaceous period, which lasted from 144 million to 65 million years ago.




Rare Fossil Embryos Reveal Dinosaur Growth National Geographic - July 29, 2005
The oldest terrestrial dinosaur embryos ever discovered reveal a strange-looking baby herbivore that was born on four legs, not two, as previously thought.




Experts tell Mr from Mrs Dinosaur BBC - June 2, 2005
Palaeontologists think they have found a way to tell whether dinosaur fossils are from males or females. Writing in Science, a US team describe a specialised type of bone layer in fossils from a T. rex which is similar to one found in female birds.nIn birds, the special tissue is called medullary bone and is laid down in the limbs of females when they lay eggs.




Utah: Killer dino 'turned vegetarian' BBC - May 4, 2005
The "mass graveyard" of a bird-like dinosaur has been uncovered in Utah, US, Nature magazine reports this week. Scientists believe the previously unknown species was in the process of converting to "vegetarianism" from a rather more bloodthirsty diet. Falcarius utahensis seems to represent an intermediate stage between a carnivorous and herbivorous form. The creature, which lived about 125 million years ago, provides a "missing link" in dinosaur evolution.




Eggs found inside dinosaur fossil BBC - April 15, 2005
A dinosaur that died just before it was about to lay two eggs has been found by an international team of scientists. The creature, which lived 65-98 million years ago, was discovered in China's Jiangxi Province. The fossilized remains comprise little more than a pelvis with the shelled eggs still viewable in the body cavity. Tamaki Sato and colleagues tell Science magazine the dinosaur's reproductive system shares similarities with both primitive reptiles and modern birds.




T. rex fossil has 'soft tissues' BBC - March 24, 2005
Dinosaur experts have extracted samples of what appear to be soft tissues from a Tyrannosaurus rex fossil bone. The US researchers tell Science magazine that the organic components resemble cells and fine blood vessels. In the hotly contested field of dino research, the work will be greeted with acclaim and disbelief in equal measure.What seems certain is that some fairly remarkable conditions must have existed at the Montana site where the T. rex died, 68 million years ago.




Fierce badger-like mammals ate dinos for lunch BBC - January 12, 2005
An astonishing new fossil unearthed in China has overturned the accepted view about the relationship between dinosaurs and early mammals. The specimen belongs to a primitive mammal about 130 million years old and its stomach contents show that it ate young dinosaurs called psittacosaurs.




Fossil Egg Finds Yield Clues to How Pterosaurs Lived National Geographic - December 2, 2004

The discoveries of two fossilized eggs from the ancient flying reptiles known as pterosaurs were announced Wednesday. The finds raise to three the number of known pterosaur eggs - the one other known egg was only announced last summer. Until very recently, scientists wondered if the reptiles that filled the skies in the age of the dinosaurs laid eggs or gave birth to live young like mammals do.




Britain's biggest dinosaur found - Isle of Wight BBC - November 22, 2004
Fossil hunters on the Isle of Wight have unearthed bones from the biggest dinosaur so far discovered in the UK. One fossil - a single neck bone from the 125-130-million-year-old sauropod dinosaur - measures an astonishing three-quarters of a metre in length. Based on this, a team of UK and US researchers believes the huge reptile was probably over 20m long and could have weighed as much as 40-50 tones.

Fossil hints at devoted parenting in dinosaurs Nature - September 24, 2004
Fossil hunters in China have unearthed what looks like the final resting place of an adult dinosaur with 34 offspring. The unique discovery shows that at least some dinosaurs cared for their young after they hatched out, and suggests that the parental instincts of present-day birds and reptiles such ascrocodiles may have a common evolutionary precursor.

The earliest known bird was discovered in a Bavarian quarry in 1861. Ever since, scientists have disagreed as to whether Archaeopteryx was fully capable of flight. Exquisitely preserved fossils reveal that the winged, feathered animal had numerous modern birdlike features, but much of its primitive reptilian skeleton betrays a close kinship to meat-eating dinosaurs.




Dinosaur Tooth Found in Flying Reptile's Spine National Geographic - June 30, 2004
A hundred-million-year-old Brazilian fossil may offer rare evidence of an ancient encounter between a dinosaur predator and a flying reptile. Massive carnivorous dinosaurs known as spinosaurs had snouts and jaws similar to modern fish-eating crocodiles. The similarity led many experts to believe that they were specialized hunters of fish.




Two Dinosaurs From Africa Give Clues To Continents’ Split Science Daily - June 9, 2004
The fossil skull of a wrinkle-faced, meat-eating dinosaur whose cousins lived as far away as South America and India has emerged from the African Sahara, discovered by a team led by University of Chicago paleontologist Paul Sereno. The find provides fresh information about how and when the ancient southern continents of Africa, South America and India separated.




"Wrinkle Face" Dinosaur Fossil Found in Africa National Geographic - June 2, 2004
The fossil skull of a new species of dinosaur - a wrinkle-faced carnivore called Rugops primus that lived 95 million years ago - has been found in a remote part of the Sahara in Africa. The discovery of the 30-foot-long (9-meter-long) dinosaur -whose cousins lived as far away as South America and India - sheds new light on how and when the ancient southern continent that included Africa, South America, and India separated.




New dino 'links major landmasses' BBC - June 2, 2004
A cache of dinosaurs discovered in Niger may challenge our understanding of continental formation, US scientists have claimed this week. One of the dinosaurs - Rugops - was a wrinkle-faced carnivore, which lived about 95 million years ago. Rugops had relations in South America, indicating Africa became a separate continent later than thought, some researchers believe.




Dino hunts find 7 rare raptor teeth BBC - April 26, 2004
Seven fossil dinosaur teeth unearthed on the Isle of Wight belong to raptors - the predatory dinosaurs made famous by the film Jurassic Park. The teeth represent only the second example of velociraptorines in the UK and suggest the animals from which they came were surprisingly large.




Argentina: Dinosaur Discovered in Patagonia - Named "Small Head" National




Argentine paleontologists have discovered a 13-foot (4-meter) plant-eating dinosaur with a long neck and small head that roamed the southern tip of South America about 70 million years ago. The team, led by Fernando Novas of the Argentine Museum of Natural Sciences in Buenos Aires, named the dinosaur Talenkauen santacrucensis. Talenkauen means "small head" in the Aonikenk Indian language.




Spain: One of the World's 'largest dinosaur' found BBC - February 27, 2004
Archaeologists in Spain say they have discovered fossil bones belonging to one of the world's largest dinosaurs. The bones of a what would have been a 35m-long (about 115ft) creature weighting 50 metric tons were found near Riodeva in the eastern province of Teruel. It is thought to have lived in the Lower Cretaceous period between 110m and 130m years ago. The dinosaur has not yet been fully identified, but it is apparently a herbivorous sauropod similar to the Paralititan found in Egypt.




Dinosaur fossils found in Amazon BBC - January 15, 2004
The Federal University in Rio de Janeiro said its researchers found the remains of a new species of dinosaur, estimated to be 100 million years old. The dinosaur is part of a group of long-necked, long-tailed plant-eaters called sauropods.




Dinosaur family footprints found BBC - December 2, 2003
A rare piece of evidence pointing to a dinosaur mothering her young after they had left the nest has been discovered on the Isle of Skye. Dinosaur footprints found on a remote beach on the island reveal an adult ornithopod - a bipedal plant-eating dinosaur - walking along a muddy lake edge, with up to 10 smaller individuals.




Ancient pterosaurs 'could have outperformed modern birds' BBC - October 23, 2003
Pterosaurs were not cumbersome gliding dinosaurs, but nimble and athletic flyers, scientists now believe. The ancient reptiles, which flourished 251 to 65 million years ago, might even have outperformed modern birds. Researchers examined 3D images of their brains and found the regions relating to balance were particularly pronounced - suggesting pterosaurs would have been agile swoopers and divers.




Ancient, Lizard-Like Reptile Discovered National Geographic - October 8, 2003
A pair of Argentine paleontologists have discovered numerous 90-million-year-old fossils of a new type of sphenodontian - an ancient lizard-like reptile thought to have gone extinct about 120 million years ago except for a few relicts that live today in New Zealand, the tuatara. The fossils, including several well-preserved skulls, were found in the red sandstone cliffs of the La Buitrera fossil quarry in northwestern Patagonia, about 800 miles (1,300 kilometers) east of Buenos Aires.




New dino species found in India BBC - August 13, 2003
Scientists in India have discovered a new dinosaur species that roamed the Narmada valley 65 million years ago. The creature, whose fossilised bones were scattered along the Narmada River in the western state of Gujarat, has been named Rajasaurus narmadensis, or the regal reptile from Narmada.




New dinosaur identified in South Africa July 10, 2003 - National Geographic
Neglected for 20 years on the dusty shelves of a South African university, paleontologists have re-discovered the 215-million-year-old fossils bones of one of the earliest giant dinosaurs.




Flap over dino flight origins BBC - January 16, 2003
A new theory of how dinosaurs learned to fly has emerged. According to a US scientist, flight may have evolved in two-legged dinosaurs that flapped their feathered fore-limbs to climb slopes. They eventually developed true wings and became f







Cuba: Dinosaur First Confirmed Remains Discovered December 20, 2002 - National Geographic
The roughly 150-million-year-old vertebra of a small, coastal-dwelling Saurischian dinosaur was unearthed in the Sierra de los Organos Mountains in western Cuba.




England: Remains of Prehistoric 'sea dragon' found BBC - October 24, 2002
The plesiosaur, which resembles the Loch Ness monster, dates back to the beginning of the Cretaceous period 130 million years ago.




"Mummified" Dinosaur Discovered In Montana National Geographic - October 11, 2002
Leonardo, a mummified, 77-million-year-old duck-billed dinosaur was only about three or four years old when he died, but he's proving to be a bonanza for paleontologists today.




Battle of the sexes 'prehistoric style' - Dinosaurs BBC - September 13, 2002
Dinosaurs took part in mighty displays to attract a mate, a US scientist has proposed. The males showed off their ornate frills and crests, while the females looked on, said Scott Sampson of the Utah Museum of Natural History




Dino family tree shows birds are related June 10, 2002 - BBC

Scientists have produced the most detailed family tree of dinosaurs yet, showing how the great beasts were related to each other and how they evolved. The researchers, from the University of Bristol, UK, took over 150 previously published evolutionary trees of dinosaurs and combined them into a new supertree of 277 dinosaur species. This new look at dinosaur evolution clearly shows that birds are descended from dinosaurs, a matter of much debate in recent years.




Dino heatwave recorded in leaves June 11, 2002 - BBC
Fresh evidence to show an impact from space lay behind the demise of the dinosaurs has been published by scientists. The only thing that can explain such a large and sudden jump in CO2 would be this idea of a space impact. The researchers say analysis of fossil leaves from 65 million years ago shows there was a sudden and dramatic rise in carbon dioxide in the Earth's atmosphere.




The biggest was not necessarily the best nor the fastest BBC - February 27, 2002
A new study suggests that the "king" of the dinosaurs was probably something of a slowcoach, incapable of breaking into a sprint and catching the most agile of prey.




The most primitive wishbone yet found in a dinosaur BBC - February 18, 2002
Sensational fossil discoveries were unveiled on Monday, including the most primitive wishbone yet found in a dinosaur. Also presented was an exquisite skull from a tiny crocodile that could help provide vital new evidence on when the landmasses of Africa and South America split to take up their current positions on the planet's surface.




How reptiles survived the big one BBC - September 25, 2001
Fossils of reptiles that survived the greatest extinction in the Earth's history suggest that the catastrophe had a far greater impact on ocean life than on land-dwellers. The theory that an asteroid or comet slammed into the planet, wiping out most living things, may have to be revised following the discovery. Scientists have found that two-thirds of a group of ancient land reptiles managed to escape the devastation, while about 90% of marine life died out.




More 'feathered' dinosaurs found BBC - June 18, 2001
Scientists in America claim to have discovered two new "bird-like" species of feathered dinosaur, unearthed in New Mexico. The two dinosaurs - the sloth-like Nothronychus and a small carnivore from the coelurosaur family that has not yet been named - lived 90 million years ago in swampy forests.
