Late Triassic, 237 to 201 million years old.

Postosuchus is an extinct genus of rauisuchid archosaurs that roamed North America during the Late Triassic period (237–201 million years ago). Belonging to the same archosaur lineage that gave rise to crocodilians and dinosaurs, Postosuchus was one of the largest terrestrial predators of its time, measuring 4–5 meters in length with a robust body, strong limbs, and a long tail built for speed and agility.

Its skull was armed with large, serrated teeth, perfectly adapted for hunting and tearing the flesh of prey, indicating a strictly carnivorous diet. Anatomical traits reveal similarities to both early crocodilians and dinosaurs, marking it as a key species in archosaur evolution.

Fossil evidence from Pangaea regions of North America highlights Postosuchus as a dominant Late Triassic predator, preying on smaller reptiles and early mammals, and provides critical insight into the ecology of prehistoric terrestrial ecosystems.
