Armoured Stegosaurus had large plates along its back and distinctive tail spikes. Although the spikes were undoubtedly used for defence, their function is not completely understood. The plates were probably used for display and species recognition, but grooves left by blood vessels suggest they could also have been used to regulate body temperature. Stegosaurus had a very small brain. Simple jaws and teeth indicate it probably fed on soft leaves and fruits.
