Ankylosaurus is one of the largest armor-plated dinosaurs ever discovered. This animal was approximately 30 feet long, 6 feet wide, 4 feet tall, and weighed right around 4 tons. It has many large oval plates that were fused into its leathery skin, and these plates covered this dinosaur’s entire body except for its belly, which would have been exposed. This dinosaur also had two rows of spikes that traveled down its body, large horns on top of its head, and a club-like tail that had spikes on it. All of this armor was necessary for it to protect itself from some of the apex predators of the time including the T Rex, Deinonychus, and Tarbosaurus. The only way any of these predators could wound the Ankylosaurus would be for them to attack the underbelly of this dinosaur where there wasn’t any armor.

These dinosaurs were herbivores—meaning they fed on plants and trees. Since its teeth were insufficient to crush plant matter, it more than likely used their teeth to strip leaves from branches. They would then use fermentation to break down this plant material in their guts.
