The four-ton Stegosaurus was equipped with an unusually small brain, only about the size of a dog's. It was once proposed that this none-too-bright herbivore had supplementary grey matter located in its hip region, but paleontologists quickly soured on this "brain in the butt" theory.

The name Stegosaurus means "roofed lizard," reflecting the belief of 19th-century paleontologists that this dinosaur's plates lay flat along its back. Various reconstructions have been offered since then, the most convincing of which has the plates alternating in parallel rows (and facing pointy side up) along Stegosaurus' spine.
