Scientists describe the ‘awful’ croc with ‘the size of a banana’ teeth.



To borrow a quote from Sisqó – these prehistoric crocs had “dump like a truck”.

Paleontologists are revealing new details about an ancient reptile described as the size of a city bus – growing up to 33 feet in length – and possessing teeth. “As big as a banana”.

According to the study authors, species of the genus Deinosuchus, which literally means “terror crocodile”, once roamed the United States. During Deinosuchus’ reign 75 to 82 million years ago, the country was divided by the Western Inland Sea, an ocean that once covered many southern and Midwest states, as well as parts of central Canada and eastern Mexico.

The habitats of D. hatchheri and D. riograndensis can be found west of the Cretaceous Sea, from northwestern America to northern Mexico. Meanwhile, their East Coast brothers, D. schwimmeri, married along the Atlantic coastal plains, from the Northeast to the Gulf.

Dr Adam Cossette, study co-author from Arkansas State University, Arkansas State University, said: “Deinosuchus was a giant who had to terrorize dinosaurs to the edge of the water to drink. “Up to now, the complete animal is unknown. These new specimens we examined show a bizarre, monstrous predator with teeth the size of a banana.

Their findings on the Cretacecous crocodylians, published in the Journal of Vertebrate Paleontology, described a diet of almost anything, due to their ferocious stature. They were even known to have dinner with their reptile dinosaur cousins.

In fact, Deinosuchus is more closely related to the crocodile than the crocodile, the researchers noted, but their oversized skull is unique to both organisms. They describe a long and broad snout, with an onion-shaped nose that is not seen in other crocodylians, including other extinct species.

“It has two large holes. . . Cossette said at the tip of the snout before the nose. “These holes are unique to Deinosuchus and we don’t know what they are for, further research will hopefully help us uncover this mystery and we can learn more about the amazing creature. this. “

Although the Deinosuchus lived with the dinosaurs, their race disappeared even before the Cretaceous-Paleogen extinction event, finally bringing the reign of dinosaurs to an end.

“It’s a strange animal,” co-author Christopher Brochu, from the University of Iowa, said in a statement. “It shows that crocodylians are not ‘living fossils’ unchanged since the dinosaur era. They have grown dynamically like any other group. “
