Tyrannosaurus lives up to its reputation as one of the most fearsome animals of all time. Its powerful jaws had 60 teeth, each one up to 20cm (8 inches) long and its bite was around 3 times as powerful than that of a lion.
Bite marks found on Triceratops and Edmontosaurus fossil bones show that Tyrannosaurus could crunch through bone. Analysis of fossilised Tyrannosaurus dung show that it contained the bones of its prey.
