History: Stegosaurus was a giant plant eater from the Jurassic period. It had two rows of bony plates on its back and a strong, powerful tail with spikes on it, which it used to defend against Allosaurus and other large predators. Died out at the end of the Jurassic.
Stegosaurs are weird looking and distinctive, and known as a fighter due to it's tail spikes. However, it is better known for the size of its brain, which is ludicrously small for it's body size. Other then the tail, it doesn't have much to fight with either. Its jaws are week, and the plates on its back are more useful for mating purposes. Still, it is a large powerful dinosaur, and those tail spikes would not be good to get whacked by.
(Stego is a representative of all the large animals with brains the size of walnuts)
