The Ankylosaurus ranks among the largest armor-plated dinosaurs ever unearthed, measuring approximately 30 feet in length, 6 feet in width, and 4 feet in height, with a weight nearing 4 tons. Its body was enveloped in numerous large, oval plates seamlessly integrated into its tough, leathery skin, leaving only the underbelly exposed. This dinosaur featured two distinct rows of spikes along its back, prominent horns atop its head, and a spiked, club-like tail. Such formidable armor served as essential defense against apex predators of its era, including Tyrannosaurus rex, Deinonychus, and Tarbosaurus. These predators could only inflict injury by targeting the vulnerable, unarmored underside.
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 its teeth to strip leaves from branches. They would then use fermentation to break down this plant material in their guts.
