At a first glance, prosauropods (“before the sauropods”) seem simple variations of a single dinosaur: always with the mixed theropod/sauropod shape that characterize the stock species, Plateosaurus. Actually their resemblance was not necessarily a real sign of relationship: their bodyplan was simply a primitive condition, shared by all most archaic sauropodomorphs. According to recent classifications, the prosauropods in traditional sense can be divided in three ensembles: “core prosauropods”, “near sauropods” and “really basal sauropodomorphs”. The first were typical "prosauropods", large to medium-sized bipedal dinosaurs intermediate between more basal sauropodomorphs and proper sauropods. The second ones were more closely related to sauropods and gave rise to them, and were usually larg
