Ankylosaurus ranks among the largest armored dinosaurs discovered to date, measuring roughly 30 feet in length, 6 feet in width, and 4 feet in height, with an estimated weight of about 4 tons. Its body was extensively covered with large, fused oval osteoderms embedded within its tough skin, leaving only the ventral side unprotected. Two parallel rows of spikes ran along its back, complemented by prominent cranial horns and a distinctive tail club adorned with spikes. This extensive dermal armor served as an effective defense mechanism against apex predators like Tyrannosaurus rex, Deinonychus, and Tarbosaurus, with the unarmored belly remaining the sole vulnerable area.
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.
