Just think — millions of years ago on our planet there were hundreds of kinds of dinosaurs and a huge meeting with any of them for the modern man would equal certain death. Dangerous ancient giants was undoubtedly bloodthirsty tyrannosaurs with the strongest bite among all that existed on the planet terrestrial animals. It is known that due to its strong jaws of Tyrannosaurus could easily bite through thick bones of their victims. In the movie “Jurassic Park,” 1993, Director Steven Spielberg even showed how a huge dinosaur bites through the car and recently scientists have proven that the giants were really capable of. But they didn’t break his skull, prakusya thick metal?
About the record the bite force of T. Rex scientists have known for a long time — in the remains of their feces were often traces of digested bones. The researchers could not understand how they ate so much solid food. The fact that for many years, paleontologists believed that the skull of T. Rex was flexible like birds and snakes, that is, its parts can move in different directions. This feature helps snakes to completely swallow even the people, but the tyrannosaur flexible structure of the skull to anything. But the solid skull without moving parts, like crocodiles, they would be most welcome — another amazing feature of the T. Rex to bite through bones not to explain.
How powerful was a Tyrannosaurus?
In different sources the bite force of T. Rex indicated differently. Most of them said that it is equal to 34 000 Newtons. Most likely, this figure is already outdated, because in the new study, the researchers, led by Professor Ian Costa took as a basis a doubling of power equals 64 000 Newtons. This means that the bones were the force equal to 7.1 tons.
By the way, long ago, tyrannosaurs were very small
To check whether tyrannosaurs had a solid skull, scientists have recreated it in the form of a computer model. On the head with a length of 1.8 meters and a height of 1.2 meters were first imposed flexible joints as in birds and reptiles. After reviewing the resulting design, the researchers came to the conclusion that the skull with an abundance of moving parts would not have allowed the T. Rex to bite through the bones of their victims when the above mentioned force of a bite, he simply could not stand such a load.

How truthful movies?
But in the absence of moving parts tyrannosaurs could with appetite to chew even the thickest bones. About the car from the movie “Jurassic Park” and say nothing, because a huge dinosaur would have easily handled him. He could not prevent is that of glass, sharp metal and spilling gasoline, but the fact remains — Tyrannosaurus could easily bite the body of the car.
Scientists constantly study the tyrannosaurs and each time discover something new. For example, in the scientific community today is very popular assumption that they were covered with feathers, the artists even painted, as were the tyrannosaurs, if this theory is really true. And the assumption may indeed be true, because evidence of the relationship of dinosaurs with modern birds today very much.
