Dinosaurs were land-dwelling reptiles that lived millions of years ago. More exactly, they lived between 230 to 65 million years ago. Dinosaurs are divided into two groups: Saurischia and Ornithischia. Saurischia (lizard-hipped) includes two suborders: Sauropoda (large, 4-legged herbivores) and the Theropoda (carnivorous bipedal reptiles). Ornithischia (bird-hipped) is an order of beaked, herbivorous dinosaurs. Dinosaurs varied greatly in form and size.
