American researchers have found that the dinosaur Tyrannosaurus rex is one of the largest land carnivores of all time — the bite produced a record pressure comparable to the weight of three cars. This enabled him to grind bones, which I can not do modern reptiles. About it reported on the website EurekAlert!.
The researchers built a model of the bite of a dinosaur, given how much power produces jaw muscles of crocodiles. They then compared the results with the birds that are direct descendants of ancient dinosaurs.
Paleontologists have established that the compression force of the jaws of a Tyrannosaurus Rex were to exceed that of the crocodiles more than two times. However, his sharp teeth, conical in shape, produced a pressure of more than 30 thousand kilograms per square centimeter.
