Giant Turtle Fossil Found

ScienceDaily (July 11, 2012) — Even the world's largest snake, Titanoboa, could probably not have swallowed this new, very round fossil turtle species from Colombia. Paleontologist Carlos Jaramillo's group at the Smithsonian Tropical Research Institute in Panama and colleagues at North Carolina State University and the Florida Museum of Natural History discovered a new species of fossil turtle that lived 60 million years ago in what is now northwestern South America.

The team's findings were published in the Journal of Paleontology.

The new turtle species is named Puentemys mushaisaensis because it was found in La Puente pit in Cerrejón Coal Mine, a place made famous for the discoveries, not only of the extinct Titanoboa, the world's biggest snake, but also of Carbonemys, a freshwater turtle as big as a smart car.

Cerrejon's fossil reptiles all seem to be extremely large. With its total length of 5 feet, Puentemys adds to growing evidence that following the extinction of the dinosaurs, tropical reptiles were much bigger than they are now. Fossils from Cerrejon offer an excellent opportunity to understand the origins of tropical biodiversity in the last 60 million years of Earth's history.

The most peculiar feature of this new turtle is its extremely circular shell, about the size and shape of a big car tire. Edwin Cadena, post-doctoral fellow at North Carolina State University and lead author of the paper, said that the turtle's round shape could have discouraged predators, including Titanoboa, and aided in regulating its body temperature.

The width of the turtle's shell probably exceeded the maximum expansion of the Titanoboa's mouth. Its circular, low-domed shape would have increased the area of the body exposed to the sun, helping the cold-blooded turtle warm to a temperature at which it was more active.

That's a huge turtle!!!

That would be a big turtle pond. What you think eggs as big as basket balls.

yup

my friend started a non profit called Paleo Quest. they are affiliated officially with the Smithsonian and national geographic. the won a research grant from the va herp society and will be giving a talk at the society's fall meeting. check them out. their findings are redefining whale evolution. but the have also found huge turtle fossils and snakes right here in va and md.
