DIET: |
Herbivore (plant-eater) - Ankylosaurus had to eat a huge amount of low-lying plant material to sustain itself
so its gut must have been very large. It probably had a fermentation compartment to aid in the digestion of the tough plant
material, producing prodigious amounts of gas! |

INTERESTING FACTS: |
Ankylosaurus was a tank-like dinosaur - its entire top side was heavily protected from carnivores with thick,
oval plates embedded (fused) in its leathery skin, 2 rows of spikes along its body, large horns that projected from the back
of the head, and a club-like tail. It even had bony plates as protection for its eyes. Only its under-belly was unplated.
Among its contemporaries were the large meat-eating Tyrannosaurus, Tarbosaurus, and Deinonychus. Short of being flipped over, the Ankylosaurus was well protected from these predators, and could even defend itself with
its club-like tail. |
