Evipitosuchus (“Stallion crocodile”) or commonly named Pterysagonisaurus (“Jaw-finned lizard”), was a large, four-legged predator, who is mostly known for it’s distinctive jaw fins.
It was quadruped, but probably mainly bipedal to chase prey. In 1962 it was mistakenly classified as a Rauisuchidae, since they had the same arms and a straight back, but the rest of Epivitosuchus’s anatomy is closer to that of Torvosaurus.
He has very long hindlegs and incredibly long arms. The large boney structure at the end of the tail was thought to be used for balance. Unlike most therapods, Epivito had a straight back, like the postosuchus, and a less visable S-shaped neck.
On his lower jaw it had remarkable fins, that may be used for mating rituals or heat regulation.The Epivitosuchus dwarved the Fasolasuchus, which was the considered biggest of the Rauisuchidae.
