Described in the latest issue of the journal PeerJ, skeletons of dinosaurs on large Daspletosaurus tyrant.
"This animal was clearly a life of pain with multiple head injuries, including injuries are very serious," the study's lead author David Hone from Queen Mary, University of London, said in a press release.

"The suspect largest in causing the injuries are the dinosaurs of the same species. This suggests that there have been quite intense battle between dinosaurs together. "
Daspletosaurus species living in North America about 77 million years ago. "Victims" dinosaur above are derived from Alberta, Canada today. When you die, it only reaches adolescence, so its size is not fully developed. However, this is still a very large animal. It's about more than 6 meters long and weighs about 500kg.
The analysis shows that in the skull of the dinosaur has many wounds have healed. Hone explained that not all bite wounds are, but there are a few spots shaped like the teeth of Tyrannosaurus rex. One bite at the back of the head had broken part of the skull and leave a hole shaped teeth through bone.
According to the researchers, the changing surface of the skull showed that the injury does not directly cause death.
However, dinosaurs did not last then. Skull with jaw injuries suggests dinosaurs were stillborn and starts to disintegrate. Just then, a huge Tyrannosaurus rex - is likely to be the same species - have grabbed on dinosaurs died, and probably ate meat part of it.
The skeleton is analyzed unique in that it provides evidence for the war between the dinosaurs of the same species, and even cannibalistic behavior.
T-Rex dinosaur closely related to Daspletosaurus. Basically, they are cousins, and have dimensions similar maturity. So many possibilities for T-Rex dinosaurs and other species of tyrant has similar behavior Daspletosaurus. /.
