Rutiodon


Rutiodon 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. Rutiodon is known from the eastern United States.

Description

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.
Rutiodon was among the largest carnivorous animals of its environment, measuring 3–8 meters in length.

Species

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.
