Saurischia (Greek: σαυρος sauros; and ισχιον ischion; "lizard-hipped"), one of the two major orders of the dinosaurs which were arranged in 1888 on the basis of many species sharing a common structure of the pelvic bones. Saurischian dinosaurs are again divided into two suborders: the Theropoda - carnivorous dinosaurs including Tyrannosaurus rex; and Sauropodomorpha, which were mainly long-necked herbivores, some of which were the largest animals to have walked the earth.
