Meaning - Ankylosaurus means “fused lizard”
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!
Length - 25-35 feet (7.5-10.7 m) long
|WHEN IT LIVED||
Late Cretaceous period, about 70-65 million years ago
|WHERE IT LIVED||
Ankylosaurus fossils have been found in the western USA (Montana) and Canada (Alberta), North America.
Two Ankylosaurus skulls and three partial skeletons (including armor and a tail club) have been found. Ankylosaur trackways were found near Sucre, Bolivia, South America.
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.
