Scientists take a new look at the extinct, jumbo Deinosuchus and find it truly lived up to its name.

A new study of Deinosuchus fossils has revealed more details of what these mind-boggling predators looked like and how they behaved.

Cossette and paleontologist Christopher Brochu at the University of Iowa studied cranial fossils and bite mark evidence to build a more complete picture of Deinosuchus, which was more closely related to alligators than crocodiles. .

The paper helps to clarify three different known species of Deinosuchus: Deinosuchus hatcheri and Deinosuchus riograndensis (which ranged from Montana to northern Mexico) and Deinosuchus schwimmeri (from New Jersey to Mississippi). .
