Tyrannosauruslives 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.

Hunter or scavenger?

The Tyrannosaurus skull was over 1.5m (5 feet) long and the cavity that housed the part of the brain responsible for smell was relatively large.

Tyrannosaurus would have used its good sense of smell to hunt live prey and locate dead bodies to scavenge. It would have been able to scare off any other scavengers, so it didn't have to share.
