"Fused, stiff, or bent Lizard"
A Gaseous, Plated Plodder
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. Flipping it over was the only way to wound it.
Ankylosaurus had four short legs (the rear legs were larger than the front legs), a short neck, and a wide skull with a tiny brain.
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.
DIET AND TEETH
This huge, extremely heavy reptile was an herbivore (it ate only plants). It 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!
Ankylosaurus was an ankylosaur, whose intelligence (as measured by its relative brain to body weight, or EQ) was low among the dinosaurs.
DISCOVERY OF FOSSILS
Ankylosaurus fossils have been found in the western USA (Montana) and Canada (Alberta). Two Ankylosaurus skulls and three partial skeletons (including armor and a tail club) have been found. Ankylosaurus was named by Barnum Brown in 1908. Ankylosaur trackways were found near Sucre, Bolivia, South America.
