Genus information

Stegosaurus is probably one of the most famous dinosaurs known to the general public. It lived during the Upper Jurassic epoch of North America and Europe. It was a heavily built and well-armoured dinosaur with long hind limbs, a high tail with four spines and a small head. On its back it had two rows of plates in different sizes, growing larger in the center. The function of these plates is still debated: some think they were used for display or to intimidate rivals or predators, while others even suggest they were used for thermoregulation.

Stegosaurus stenops had larger and more rounded plates on its back and shorter hind limbs compared to Stegosaurus ungulatus.
