What is something interesting about the stegosaurus?

Stegosaurus had long hind limbs and short forelimbs. Its head and neck were very low to the ground, and its head was small, with a beak that it used for cropping off vegetation. They had 17 plates on their back in two rows, one row on either side of the spines. They had four tail spikes, or thagomizers, that they used for self defense.
