What did a Tyrannosaurus Rex look like?
A Tyrannosaurus Rex was a massive bipedal creature. It had a powerful tail, a huge head and tiny arms. Scientists struggle to work out what the tiny arms were used for because they were too short to reach its mouth and too weak to be of any use in defence or hunting. It is guessed that they may have counterbalanced its enormous head, or they could have been used in mating rituals.
