Researchers reveal ancient giant turtle fossil   PhysOrg - May 17, 2012
The turtle in question is Carbonemys cofrinii, which means "coal turtle," and is part of a group of side-necked turtles known as pelomedusoides. The fossil was named Carbonemys because it was discovered in 2005 in a coal mine that was part of northern Colombia's Cerrejon formation. The specimen's skull measures 24 centimeters, roughly the size of a regulation NFL football. The shell which was recovered nearby - and is believed to belong to the same species - measures 172 centimeters, or about 5 feet 7 inches, long. That's the same height as Edwin Cadena, the NC State doctoral student who discovered the fossil.

New study shows how giant tortoises, alligators thrived in High Arctic 50 million years ago   PhysOrg - August 24, 2010
A new study of the High Arctic climate roughly 50 million years ago led by the University of Colorado at Boulder helps to explain how ancient alligators and giant tortoises were able to thrive on Ellesmere Island well above the Arctic Circle, even as they endured six months of darkness each year.

Oldest sea turtle fossil unveiled in Mexico   AFP - March 6, 2009
Paleontologists unveiled the oldest fossil remains of a sea turtle that lived 72 million years ago in northern Mexico, the National Institute of Anthropology and History (INAH) said. The fossils of seven sea turtles were found at different sites in Coahuila, the state that Mexican scientists call "the paradise of paleontology." The sea turtle inhabited the northern region in the late Cretaceous period, 72 million years ago, and is the ancestor of the present day green turtle. It is the oldest sea turtle of its kind and it belongs to the chelonia family. It was one meter (yard) long, 70 centimeters (28 inches) wide and distinguished from other turtles by its rounded head. The oldest specimen of this species up to now was 65 million years old and was found in New Jersey, US.

Tropical Turtle Fossil Found in Arctic   Live Science - February 1, 2009
The last place scientists expected to find the fossil of a freshwater, tropical turtle was in the Arctic. But they did. The discovery, detailed today in the journal Geology, suggests animals migrated from Asia to North America not around Alaska, as once thought, but directly across a freshwater sea floating atop the warm, salty Arctic Ocean. It also provides additional evidence that a rapid influx of carbon dioxide some 90 million years ago was the likely cause of a super-greenhouse effect that created extraordinary heat in the polar region. Turtles may be slow, but they're known to migrate long distances. Recent satellite tracking found a leatherback turtle traveled 12,774 miles (20,558 kilometers) from Indonesia to Oregon, one of the longest recorded migrations of any vertebrate animal.

Canada: Fossil of Ancient Pregnant Turtle Discovered Live Science - August 27, 2008
A turtle that toddled alongside the dinosaurs died just days before laying a clutch of eggs. Now, about 75 million years later, paleontologists are announcing their find of the fossilized mother-to-be and the eggs tucked inside her body.
