Ankylosaurus was a well-armoured herbivore from the Cretaceous Period. It lived in North America.
Length: 9 metresHeight: 1.7 metres (at the hip)
Weight: 3 tons
Ankylosaurus was very well armoured. Its whole body was covered in scutes and bony armour, like a bullet-proof vest. Even its eyelids were armoured.
Ankylosaurus had a massive lump of bone on the end of its tail, called a club. The club was so strong it could break an attacking T-Rex's leg bone. This made Ankylosaurus a very dangerous opponent.
