The name Tyrannosaurus rex means "king of the tyrant lizards". T-Rex had strong thighs and a powerful tail, which counterbalanced its large head and allowed it to move quickly. The king of dinosaurs needed thick neck muscles to hold up its large skull and power its forceful bite. Neck and arm muscles compete for space in the shoulder, and it appears that the neck muscles edged out the arm muscles in T-Rex's case.
