While it had a large body and several spiky plates that served as protection, the Stegosaurus had an exceptionally small brain for its body size-its brain has been compared to a walnut or lime. For some time, scientists believed the dinosaur had an ancillary group of nerves in a cavity above its rear end that helped to supplement its tiny noggin, but this hypothesis was later disproved.
