Paleontologists have described a new species of tyrannosaurs
Scientists in the US and Australia have described a new species of Tyrannosaurus Rex, lived during the upper Cretaceous, about 100-66 million years ago. According to scientists, the dinosaur was about nine metres in length and 2.2 meters in height. The he called Daspletosaurus horneri.
Paleontologists have carefully studied the bones of the skull of a dinosaur. Their uneven surface they compared with bones of crocodiles and birds to represent, what kind of fabric could cover these bones. Scientists came to the conclusion that his face was covered with a protective layer of scales with high sensitivity. This was to help animals in hunting and identifying the objects.

Considering that the location is suitable for nerve and blood vessel holes in the bones of the skull of the described type similar to the present in modern crocodiles, it can be concluded that the dinosaurs were sensitive organs, necessary for signal transmission from the skin surface.
