The head of an Ankylosaurus was relatively small compared to its overall body size, yet it had some distinct features that contributed to the dinosaur’s survival. It had a broad, triangular-shaped skull with a beak-like mouth at the front, which was useful for cropping low-lying vegetation.
The head of Ankylosaurus was also armored, with bony plates and knobs called osteoderms covering the skull, providing additional protection from potential predators. Its eyes were positioned on the sides of the skull, allowing for a reasonably wide field of vision.
