Named Stegosaurus, or "roof lizard" for it's large, flat dorsal plates, this herbivorous dinosaur is a classic favorite. Scientists debate the purpose of those trademark plates, but many suggest they were used to regulate heat. Filled with blood vessels, the plates could quickly warm the big plant-eater when faced towards the sun.
