Postosuchus z1

Postosuchus, meaning "crocodile from Post (Garza, Texas)", was a basal archosaur that lived in what is now North America during the late Triassic period (228-202 million years ago). It was a rauisuchian, a close relative of crocodiles, as a member of the clade Pseudosuchia (or Crurotarsi) which, along with the lineage that led to dinosaurs and Birds, forms Archosauria. Its name refers to Post Quarry, a place in Texas where many fossils of this genus were found. It was one of the apex predators of its area during the Triassic, larger than the small dinosaur predators of its time (such as Coelophysis). It was a hunter which probably preyed on dicynodonts and many other creatures smaller than itself.

In The Land Before Time

Postosuchus makes its first appearance in the opening narration of The Land Before Time VI: The Secret of Saurus Rock, where a red individual appears climbing on top of a rock in a swamp environment. Another individual appears in the opening narration of The Land Before Time X: The Great Longneck Migration. It appears as a large quadrupedal reptilian creature that behaves much like a crocodile. One is seen trying to catch two dragonflies. More are seen resting on a small island on a swamp. A Postosuchus appears briefly as a cameo in the opening narration of The Land Before Time XII: The Great Day of the Flyers, roaring at the top of a cliff, then dying of old age.
