Late Triassic, 237 to 201 million years old.

Postosuchus is an extinct genus of rauisuchid archosaur that lived during the Late Triassic, about 237 to 201 million years ago. Rauisuchids were large, carnivorous reptiles within the archosaur group, which also includes crocodilians and dinosaurs. As one of the largest predators of its era, Postosuchus measured approximately 4 to 5 meters and had powerful jaws with sharp teeth.

Postosuchus possessed a sturdy, muscular body, powerful limbs, and a long, flexible tail, which made it a swift and agile predator capable of chasing down prey with precision. Its large, serrated teeth were perfectly adapted for tearing flesh, confirming its role as a carnivorous hunter. Anatomical features reveal similarities to both crocodilians and early dinosaurs, highlighting its significance as a basal member of the archosaur lineage.

Fossils of Postosuchus have been uncovered in North America, in regions that were once part of the supercontinent Pangaea during the Late Triassic period. These fossil discoveries provide valuable insights into rauisuchid evolution and their role as apex predators within prehistoric ecosystems. Postosuchus likely dominated its environment, preying on smaller reptiles and early mammals, and played a crucial part in shaping the Late Triassic food web.
