SUBORDER THEROPODAThe great reptilian order of "lizard' hipped" dinosaurs, the Saurischia, can be divided into 2 distinct groups (sub' orders) on the basis of what they ate. The flesh'eaters that walked upright on 2 legs belong to the Theropoda. The plant-eaters that moved about on alL fours belong to the Sauropodomorpha (see pp. 122-133). These differences in gait are reflected in the bones of the animals' feet.
