Saurischia, from the Greek sauros (σαυρος) meaning 'lizard' and ischion (ισχιον) meaning 'hip joint')[1] is one of the two basic divisions of dinosaurs. In 1888, Harry Seeley classified dinosaurs into two orders, based on their hip structure.[2] Saurischians ('lizard-hipped') are distinguished from the ornithischians ('bird-hipped') by retaining the ancestral configuration of bones in the hip.
