Ankylosaurus was an ankylosaur that lived in the Late Cretaceous Period 68-65.5 million years ago. It lived until the final stage of the Maastrichian stage during this period. It was the largest known of its kind, and presumably lived up to the end of the Cretaceous, when the dinosaurs became extinct.


Ankylosaurus in Walking with Dinosaurs

Ankylosaurus was one of the most protected dinosaurs of its time. To protect itself, its back was covered in bony plates that were impenetrable, even its eyelids had bones in them. And if that wasn't enough, it had a giant club at the end of it's tail which was used like a medieval mace and swung an 45 degrees in either direction, it was made of soft-tissue, marrow, blood & fat. By swinging the club, it had enough force to break the leg bones of and immobilize most carnivores like Tyrannosaurus.

Ankylosaurus ate plants, was found all over North America and could grow as long as 30 ft (9m) and its named means "fused lizard".
