Ornithischia (/ɔːrnˈθɪskiə/ or-ni-THISS-kee-ə)[1] or Predentata is an extinct order o beaked, yerbivorous dinosaurs. The name ornithischia is derived frae the Greek ornitheos (ορνιθειος) meanin 'o a bird' an ischion (ισχιον) meanin 'hip joint'. Thay are kent as the 'bird-hipped' dinosaurs acause o thair bird-lik hip structur, even though birds actually belang tae the 'lizard-hipped' dinosaurs (the saurischians).

Some commonly kent Ornithischians include the horned dinosaurs (ceratopsians), armored dinosaurs (stegosaurs an ankylosaurs), Iguanodon, an the "duck-billed" dinosaurs (hadrosaurids). Bein herbivores that sometimes lived in herds, thay wur mair numerous nor the saurischians. Mony were prey animals for the theropods an wur uisually smawer nor the sauropods.
