The postosuchus was an archosaur and thus a close relative of modern crocodiles. It had strikingly ossified skin and a long, narrow snout. It usually moved on four legs. Sometimes it stood on its hind legs so that it could hold prey with its claws. When the postosuchus from Schleich Dinosaurs opens its powerful, movable jaw the sharp, dagger-like teeth become visible.
The postosuchus was named after the place it was found the city of Post in the US state of Texas.
