The crocodiles are related closely to birds and dinosaurs and are one of the most complex biological reptiles. They differ from replies in having a cerebral cortex and four-chambered heart. They are ferocious and likely threatens other living organisms. If we turn our life millions of years back, we could see crocodiles, which are as long as buses. A new study of Deinosuchus fossils has shown us that the ancient crocodiles would grow up to 33 feet in length and are more frequently compared to alligators. It believed to be lived between 75 million and 82 million years before.
Deinosuchus, relating to “terror crocodiles”, can even eat dinosaurs that would have been at their top of the food chain. Researchers examined fossils and bite marks on turtle shells and dinosaur bones to know about the morphology of the animal. These massive creatures had the banana-sized teeth that would aid in eating the dinosaurs.
Adam Cossette, a paleontologist at the New York Institute of Technology, said that the Deinosuchus must have terrorized the dinosaurs, which comes to drink water in the sides. They didn’t know how the complete animal looks like. Their noses had big holes at the tip, and the function was unknown. They identified three known species, such as D.hatcheri, D.riograndensis, and D.schwimmeri, with the use of the fossils. All these were present in different parts of the U.S.
These animals became extinct even before the dinosaurs, but the reason behind it remains unclear. Some scientists even said that the present crocodylians are not necessarily been living fossils as they just developed dynamically. Still, research needed to owe answers for the puzzling questions.
