A new study, which reviewed fossil samples from giant crocodylian, Deinosuchus, has confirmed that the monster has teeth “the size of a banana”, capable of taking down even the largest dinosaur.

And, it’s not alone!

The research is published above Journal of Vertebrate Paleontology, also revealed a variety of “terror crocodile”. Two species, okay Deinosuchus hatchheri and Deinosuchus riograndensis lives in the western part of America, stretching from Montana to northern Mexico. Other, Deinosuchus schwimmeri, living along the Atlantic coastal plain from New Jersey to Mississippi. At that time, North America was cut in half by a shallow sea stretching from the Arctic Ocean south to the present-day Gulf of Mexico.

Length up to 33 feet DeinosuchusHowever, it is known to be one of the largest, if not the largest, crocodylians ever in existence. It was the largest predator in its ecosystem, bigger than the largest predatory dinosaurs that lived with them 75 to 82 million years ago.

From previous studies of skull relics and dinosaur fossil bone bites, paleontologists have long speculated that large beasts prey on dinosaurs.

Now, this new study, led by Dr. Adam Cossette has unraveled the monstrosity and further confirmed that Deinosuchus Most definitely have head size and jaw-crushing strength to do that.

“Deinosuchus Dr Cossette, from the New York Institute of Technology’s College of Osteoarthritis, Arkansas State University, said a giant terrorized the 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.

C. Deinosuchus appears to be an opportunistic predator, and since it is so large, almost everything in its habitat is on the menu.

There are many examples of the bite of D. riograndensis and a new species described in this study, D. schwimmeri, on turtle shells and dinosaur bones.

Despite the genus’s name, which means “terror crocodile”, they are actually closely related to the crocodile. Based on its giant skull it does not look like a crocodile or an alligator. Its snout is long and broad, but bulging anteriorly around the nose in a way not seen in any other crocodylian, living or extinct. The reason for its large nose is unknown.

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

Deinosuchus disappeared before the major mass extinction at the end of the dinosaur era (Meozoic). The reason for its extinction is still unknown. From here on, the group of authors called for more research to understand more about Deinosuchus.

“It has two large holes in the tip of the snout in front of the nose,” said Dr. Cossette.

“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 this amazing creature. “
