Signs of Crocodile From Dinosaur Era Are Found

The journal Science has announced the discovery of a large sea-dwelling crocodile that lived 135 million years ago, in the middle of the dinosaur era. "Paleontologists have known about crocodiles living in the oceans since the 1800's when their fossils were uncovered in Europe. Some had even evolved flippers and a fish-like tail.... Despite its unusual shape, the 13-inch-long skull possessed telltale features like the shape of the nostrils, eye sockets and the roof of the mouth that indicated it was a crocodile. A detailed comparison by Dr. Pol with other marine crocodiles of the time indicated that the new species resembled a group with the flippers and fish-like tail." Details are here.
