Stegosaurus is best known for the large plates on its back and the large spikes on the end of its tail. Amazingly enough, this giant's brain was only the size of a walnut.
This large creature belongs to the family of dinosaurs called "duckbills" because of its long flat snout. One mummified skeleton that still had its skin was found in Wyoming in 1908.
