Ornithischia is an extinct order of beaked, herbivorous dinosaurs. They are known as the 'bird-hipped' dinosaurs because of their bird-like hip structure. Some commonly known Ornithischians include the horned dinosaurs (ceratopsians), armored dinosaurs (stegosaurs and ankylosaurs), Iguanodon, and the "duck-billed" dinosaurs (hadrosaurids). Being herbivores that sometimes lived in herds, many were prey animals for the theropods.
