'Teeth The Size Of Bananas'; New Study Paints Picture Of 'Terror Crocodiles'
A new study reveals there were multiple species of Deinosuchus, the giant crocodylians that lived 75 million years ago. They were among the largest predators in the ecosystem and ate dinosaurs.

Enormous "terror crocodiles" once roamed the earth and preyed on dinosaurs, according to a new study revisiting fossils from the gigantic Late Cretaceous crocodylian, Deinosuchus.
The research, published in the Journal of Vertebrate Paleontology, reiterates that Deinosuchus were among the largest crocodylians ever in existence, reaching up to 33 feet in length. New in this study is a look at the anatomy of the Deinosuchus, which was achieved by piecing together various specimens unknown until now, giving a fuller picture of the animal.
"Until now, the complete animal was unknown," Cossette said. "These new specimens we've examined reveal a bizarre, monstrous predator with teeth the size of bananas."
Past studies on cranial remains and bite marks on dinosaur bones led paleontologists to believe the massive Deinosuchus were an opportunistic predator, according to the press release. Fossil specimens now make it clear that Deinosuchus did indeed have the head size and jaw strength to have its pick of prey, including large dinosaurs.
Despite the nickname "terror crocodiles," Brochu said Deinosuchus were more closely related to alligators than to crocodiles but "didn't look like either one of them."
Deinosuchus had a snout that was long and broad, with the front appearing inflated unlike any other living or extinct crocodylian. On the tip of the snout is a large pair of holes. Researchers are still unsure of their function.
"Crocodiles are actually these incredibly dynamic creatures that have experienced incredible evolutionary histories, have lived in places that modern crocodiles don't live, done things that modern crocodiles don't do and have grown to sizes that modern crocodiles never achieve. That I think is the cool part [of the study], at least for me," Cossette added.
