Rutiodon

Rutiodon ("Wrinkle tooth") is an extinct genus of archosaur belonging to the family Phytosauridae. It lived during the Late Triassic period, and was about 10 to 25 feet (3 to 8 meters) in length. . The animal is known from fossils in Europe (Germany and Switzerland) as well as North America (Arizona, New Mexico, North Carolina, Texas).

Like other phytosaurs, Rutiodon strongly resembled a crocodile, but its nostrils were positioned far back on the head, close to the eyes, instead of at the tip of the snout. It had enlarged front teeth, and a relatively narrow jaw, somewhat resembling that of a modern gharial. This suggests that this carnivore probably caught fish and it may also have snatched land animals from the waterside. Also like modern crocodiles, its back, flanks, and tail were covered with bony armored plates.

In popular culture
Rutiodon is one of the best-known phytosaurs and appeared in the 2001 Discovery Channel documentary When Dinosaurs Roamed America, shown trying to attack a Coelophysis near the water's edge and missing.
