Stegosaurus is a dinosaur that likes to live in valleys or plains with low ferns and other plants. However, that hypothesis has since been rejected by many paleontologists. At one point scientists hypothesized that it had an auxiliary 'brain' - not an actual brain but a bundle of nerves - above its rear legs to help control its movements because its brain was so small. Its brain was about the size of a walnut, about the equivalent of a dog's brain, making it among the dinosaurs with the lowest brain-to-body ratio.

Stegosaurus also has a reputation for having a small brain. It was about the size of a bus, up to 9 meters (30 ft) long, but carried around two rows of protective bony plates along its back that made it appear even bigger as well as the four spikes, called thagomizers, at the end of its tail that makes it a dangerous dinosaur. Stegosaurus (meaning 'roofed lizard') was a large, plant-eating dinosaur that lived during the Late Jurassic Period, about 155 to 150 million years ago, primarily in western North America.
