T. rex bite with incredible force: two times stronger than any living creature

A deadly combination of a powerful bite, strong teeth and chewing was allowed a giant bird of prey, T. rex — to literally break the bones of their victims, scientists have found. Bones have nutritional internal cavity filled with marrow and phosphate salts. But to get access to these treats, most bone crushers should be able to bring the jaws together in order to crack the outer protective layer of bone. Some carnivorous mammals, such as spotted hyenas and gray wolves, so I can.

But among the living reptiles lovers bones do not meet, because their upper and lower teeth do not converge, not close so that they could hold. Most modern carnivorous reptiles just swallow the dice to get nutrients.

How much was biting tyrannosaurs?

Tyrannosaurs, including T. rex, had teeth similar to mammals, but fossil evidence indicates that dinosaurs somehow crushed the bones of prey. To find out how, anatomist Paul Gignac from the University of Oklahoma in Tulsa and paleontologist Gregory Erickson of Florida state University in Tallahassee studied the fossil evidence of behavior of these beings behind a Desk. Together they also studied the bite force, the only living dinosaurs — birds and crocodiles, close relatives of dinosaurs. Based on the analysis failed to estimate the pressure force of the teeth of dinosaurs.

T. rex could break bones, scientists say, thanks to the powerful bite of 34 000 Newtons (more than two times higher than that of crocodiles, the strongest of all living pokusaj) and pressure at the tips of the teeth of about 3,000 megapascals. Strong pressure teeth were allowed to create cracks that weaken bones. T. rex also repeatedly bitten in one place, using their own advantages to derive maximum benefit from its extraction.
