Late Triassic, 237 to 201 million years old.

Postosuchus is an extinct genus of rauisuchid archosaurs that lived during the Late Triassic period, roughly 237 to 201 million years ago. Rauisuchids were large, carnivorous reptiles belonging to the archosaur clade, which also includes crocodilians and dinosaurs. Postosuchus stood out as one of the largest predators of its time, measuring approximately 4 to 5 meters in length and equipped with powerful jaws filled with sharp, serrated teeth for hunting.

The anatomy of Postosuchus reveals a robust and agile predator. It had strong limbs, a long tail, and a sturdy body, enabling it to chase down prey efficiently. Its skull and teeth were adapted for tearing flesh, suggesting a carnivorous diet that included smaller reptiles and early mammals. Remarkably, Postosuchus exhibits anatomical features reminiscent of both crocodilians and dinosaurs, highlighting its position as an early archosaur lineage member.

Fossil discoveries of Postosuchus have been made in North America, in areas that were once part of the supercontinent Pangaea during the Late Triassic. These fossils provide critical insights into the evolutionary history of rauisuchids and their role in prehistoric ecosystems. As a top predator, Postosuchus played a key ecological role, maintaining balance by preying on smaller vertebrates and shaping the dynamics of its environment.
