Deinosuchus hatcheri, known as the 'terrible crocodile,' was a giant prehistoric crocodilian that lived during the late Cretaceous period. It inhabited coastal and riverine environments in what is now North America. This apex predator measured up to 33 feet, possessing robust teeth and a powerful bite, preying on dinosaurs and other large animals.

Deinosuchus hatcheri, a prehistoric species, was native to what is now North America. Fossil evidence suggests that it inhabited areas along the Gulf Coast, including modern-day Texas, Alabama, and Mississippi, extending to regions as far north as Montana and Wyoming.

Deinosuchus hatcheri lived during the Late Cretaceous period, approximately 82 to 73 million years ago. The climate during this time was warmer than today, with higher sea levels resulting in extensive coastal floodplains, swamps, and shallow marine environments.

As a large predatory crocodyliform, Deinosuchus hatcheri occupied a top-tier ecological niche within its habitat. It likely thrived in riverine and estuarine environments where it could hunt large prey, such as dinosaurs and marine animals, leveraging its powerful jaws and robust body for ambush predation.
