Researchers dust off a fossilized turtle shell found in the rock along the shore of the Puntledge River, in Courtenay, B.C., in an undated handout photo. The largest leatherbacks can grow up to 6 feet, half the size of Leviathanochelys aenigmatica, and can weigh up to 2,000 pounds.

It has been difficult for scientists to develop a consensus for the role these animals played in the evolutionary history of sea turtles, and this discovery will help fill in those gaps. The paper says that this discovery shows that gigantism in marine turtles evolved independently in different groups in Europe and North America, where fossils of Ctenochelys acris and Peritresius ornatus and other ancient sea turtles have been found. “This conjecture is based on the fact that the shell presents some peculiar marks that could be from bites, and that a shark tooth was found near the skeleton.” ![]() “It is still too early to say for sure, but it is likely that the turtle was preyed on by sharks,” said Sellés. Scientists believe that modern sea turtles are derived from marsh-inhabiting ancestors that lived during the Late Triassic period. The earliest known sea turtles appear in the fossil record in the Early Cretaceous period, about 110 million years ago. But there may be one tiny clue to its predators. The first turtles appeared during the Triassic period, 245 to 209 million years ago. The world's oldest sea turtle fossil shows the ancient animal swam the oceans at least 120 million years ago, when dinosaurs still roamed the Earth, according to a recent analysis. Further study will be needed to learn more about what Leviathanochelys aenigmatica ate-and who ate it. 37 minutes ago &0183 &32 STORY: Holding banners reading 'We wont pay for fossil (fuels),' members of the 'Ultima Generazione' poured what they said was vegetable charcoal into the fountain.Police removed the activists from the water in front of a group of Romans and visitors.
