Tyrannosaurus Rex was a Cannibal


Tyrannosaurus Rex was the most powerful and fiercest dinosaur that roamed the earth during the Mesozoic period. Scientists have now found out that the dinosaur was a cannibal that ate other dinosaurs. They have found marks on the bones of a T.Rex that could only have come from another tyrannosaur. They result when a dinosaur strips meat off a victim.
Researchers say that the marks on the bones happened while the tyrannosaur was feeding. They are unsure however if the beast was already dead when it was eaten or if T.Rex killed an enemy and then ate it.

For modern carnivores, like lions, bears or alligators,  such a behaviour is not unusual. They take out their enemies and have food at the same time. Cannibalism is widespread throughout the animal world.  Female spiders , for example , eat their mates, chimpanzees feed on small babies and sharks that eat their younger ones.
