Stegosaurus. Illustration of Stegosaurus dinosaurs roaming around a prehistoric landscape. Stegosaurus was a slow, lumbering dinosaur that could grow up to nine metres long. Its feeble jaws and teeth indicate it was a herbivore, feeding on primitive plants like the ferns seen here. The distinctive spines running in two rows along its back are thought to have helped control body temperature by radiating or absorbing heat. Not the most quick-witted of dinosaurs, Stegosaurus had a brain that was little bigger than a walnut, a fact that may explain why dinosaurs are often thought of as moronically stupid.
