Stegosaurus

Stegosaurus was a large quadruped, characterized by distinctive kite-shaped plates running down the length of its back. The tail had four large spikes, which were probably used as defense against predators. Stegosaurus had a small head relative to its body size, and most likely fed on bushes and shrubs. It grew up to 7.5 m in length, and weighed around 5 t.
