An ancient crocodile species has been discovered with molar teeth that fit together much like those of small carnivorous mammals. With lanky limbs, a lack of stiff armor on its back, and a nose ill-equipped for the water, it likely acted much more like a terrestrial cat than a fierce water predator.
“All of the things we’re finding really paint a picture of an animal that was active, agile, living up on land, moving around,” said anatomist Patrick O’Conner of Ohio University, lead author of the discovery August 4 in Nature. “When we look at the teeth compared to animals alive today, some of the closest comparisons are mammalian carnivores specialized for processing meat.”"
