Although the tyrannosaurus rex looked quite threatening, it could hardly use its front legs armed with just two claws since they did not even reach his mouth. Nearly seven metres tall and thirteen metres long, the tyrannosaurus rex was probably not a very skilled hunter, but rather a scavenger which probably fed on the leavings of other animals. It had more than fifty teeth measuring more than 15 centimetres in length which it used not for chewing but rather for tearing, since it swallowed its food in large chunks.
