Stegosaurus
The skull of Stegosaurus was long and narrow. Because of its short front legs, its head was close to the ground, probably no higher than 1 m (3.3 ft). It ate low-growing plants because of this. It had no front teeth, but it did have a horn-covered beak. Stegosaurian chewing teeth were small and triangular and did little grinding as they lacked wear surfaces.
