Otozoum

Otozoum ("giant animal") is an extinct ichnogenus (fossilized footprints and other markings) of sauropodomorph dinosaur from the Late Triassic-Middle Jurassic sandstones.

Footprints were made by heavy, bipedal or, sometimes, quadrupedal animals with a short stride that walked on four toes directed forward.

In 1953, Yale University paleontologist Richard Swann Lull revised Hitchcock's work, suggesting that the track maker might have been a prosauropod.

Other sources have been proposed, including a crocodile-like animal (e.g. the phytosaur Rutiodon), or an ornithopod dinosaur, although later osteological comparisons support Lull's hypothesis that the track maker was indeed a prosauropod.

[2][4] Otozoum grandcombensis from the Late Triassic ‘Grès supérieurs et Argilites bariolées’ Formation lived in a wide flood plain which also served as a habitat for theropod Grallator andeolensis.
