Ankylosaurus, the "Fused Lizard," is a dinosaur that all tanks could take some notes from. At about eight meters long and over one meter tall, the Ankylosaurus put every part of its hefty body to work in protecting itself. Its armor consisted of massive knobs and boney plates embedded in the skin called osteoderms. These osteoderms were light and sturdy, and they were highly resistant to penetrative objects like the teeth of predators. When it felt threatened, it employed its powerful tail club against other dinosaurs, oscillating its tail in a hundred-degree motion. The placement of the club at the end of the tail adds to its inertia, causing massive damage to opponents. The Ankylosaurus lived in North America during the late Cretaceous Period alongside fierce predators and competition. Its incredible defense mechanisms protected it against massive carnivores like Tyrannosaurus. Ankylosauus occupied a similar niche to herbivores like Triceratops, its wide mouth allowing it to feed on a variety of low vegetation in its subtropical floodplain environment. As the largest known ankylosaurid, the amount of food that passed through its large digestive system would have been immense. This hungry herbivore would not have stripped the region bare, though, because it likely lived solitary as an adult.
