Dinosaur classification

From CreationWiki, the encyclopedia of creation science

Dinosaurs are divided into two orders, the Saurischia and the Ornithischia, on the basis of their hip structure.

• Saurischia (from the Greek meaning "lizard hip") include all the theropods (bipedal carnivores) and sauropods (long-necked herbivores).

• Ornithischia (from the Greek meaning "bird-hip") is the other dinosauria order, most of which were quadrupedal herbivores.
