Prestosuchus amidst cycads

A 15-foot-long, 500 pound rauisuchian archosaur of the genus Prestosuchus wanders amidst cycads and ferns in swamp 230 million years ago in what is today Brazil. With long powerful legs, sharp teeth and a crocodile-like body, Prestosuchus was probably an ambush predator and likely a fast runner.

In the foreground to the right of the Prestosuchus is a foot-long prehistoric labyrinthodont amphibian.
