Ankylosaurus was a vegetarian that lived around 70 to 65 million years ago during the late Cretaceous period. It was an armoured dinosaur with heavy plates attached to its thick skin over the whole of its upper side. Two rows of horns ran down its back and horns projected from its head. On the end of its tail there was a large oval club that Ankylosaurus could actively defend it self with. Contemporary predators would have included Tyrannosaurs rex and Deinonychus.

Ankylosaurus means "fused lizard" and was named by Barnum Brown in 1908. Fossils have been found in North Western America.
