Prehistoric Crocodile was a "Carolina Butcher"
Bipedal crocodile ancestor lived 230 million years ago
The fossils were studied by paleontologists from North Carolina State University, including graduate student Susan Drymala. Carnufex carolinensis, or 'Carolina Butcher', filled the role of top predator during that period.
It did not survive the mass extinction at the end of the Triassic, but smaller bodied crocodile ancestors did, and gave rise to the species we know today.
