Stegosaur Dinosaurs

Scientific Classification
  Kingdom Animalia
  Phylum Chordata
  Class Sauropsida
  Superorder Dinosauria
  Order Ornithischia
  Suborder Thyreophora
  Infraorder Stegosauria
The Stegosauria (meaning "roof lizards") dinosaurs were a infraorder of the the Ornithischian dinosaurs. Together with the Ankylosaurs, Stegosaurs form the Thyreophora ("shield bearers") suborder of Ornithischia. Dinosaurs in the Stegosauria infraorder include Stegosaurus (of course!), as well as, among others, Gigantspinosaurus, Kentrosaurus, and Tuojiangosaurus.

Stegosaurs first appeared during the middle Jurassic period, and survived until the early Cretaceous period. They had all died long before the time that the other remaining non-avian dinosaurs became extinct at the end of the Cretaceous period.

Dinosaur Classification

All Stegosaurs were herbivores (plant-eaters). They were quadrupedal (walking on four legs), with hoof-like toes on all four legs, although it is thought that some species may have been able to rear-up on their hind legs to eater higher-placed foliage. The front limbs of Stegosaurs were shorter than their hind limbs, and as a result they are thought to have been slow-moving.
