Crocodilians first appeared about 84 million years ago during the late Cretaceous. Crocodilians are diapsids, a group of reptiles that possess two holes on each side of their skull.
Other diapsids include dinosaurs, pterosaurs, and the squamates, a group that encompasses modern lizards, snakes and worm lizards.
They usually feed on live animals such as birds, small mammals and fish. They will, at times, feed on dead animals.
