Ornithischia or Predentata is an order of beaked, herbivorous dinosaurs. They are known as the "bird-hipped" dinosaurs because of their hip structure, even though birds actually descended from the "lizard-hipped" dinosaurs (the saurischians). Being herbivores that sometimes lived in herds, they were more numerous than the saurischians, as they were prey for the theropods and were smaller than the sauropods.
