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 3 to 8 meters in length.[1] Rutiodon is known from the eastern United States (North Carolina, New York, New Jersey).[2]
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.[1] Also, like modern crocodiles, its back, flanks, and tail were covered with bony armored plates.[3]
Rutiodon was among the largest carnivorous animals of its environment, measuring 3–8 meters (10–26 ft) in length.
The type species of Rutiodon is R. carolinensis. A second species, R. manhattanensis, was discovered in 1910 near Fort Lee, New Jersey, and named in reference to its close proximity to Manhattan.
