Dinosaur Cannibalism
They believe the attacker was either another Gorgosaurus or a Daspletosaurus. Gorgosaurus attacking a Parasaurolophus
Paleontologists have discovered possible evidence of dinosaur cannibalism among dinosaurs known as Gorgosaurus. Due to this fact, researchers believe that it is more likely that the two meat-eating dinosaurs involved in the fight to the death were both gorgosaurs. Cannibalism is atypical among dinosaurs. The fossil evidence was discovered in Dinosaur Provincial Park in southern Alberta. Prior to this discovery of possible cannibalism, there has only been one confirmed case of cannibalism among dinosaurs of the same species. Upon examining the fossil remains of the jawbone of a Gorgosaurus, researchers discovered a piece of a tooth lodged within the jawbone. The researchers were not able to exactly confirm which dinosaur the tooth belonged to but were able to narrow down the possibilities to two dinosaur relatives. These enormous meat-eating animals were a smaller relative of the Tyrannosaurus rex. Learn more about this discovery:
