Ankylosaurus

Ankylosaurus (ANK-kile-OH-saw-RUS meaning Fused Lizard) was a dinosaur in the Late Cretaceous Period. It had a huge hammer on its tail and had armoured spikes to protect itself from large carnivores like the giant T-rex and it was like a big tank. It was disovered in Montana, USA, Wyoming, Alberta, and Canada and it was discovered by Brown in 1980. More Real Life Information: Ankylosaurus at Wikipedia
