Early sauropodomorphs
Early sauropodomorphs were the forerunners and early cousins of the giant sauropods. Most had long necks and small heads, and many could walk on two legs as well as four.
They were among the most common plant-eaters of the Late Triassic and Early Jurassic. Plateosaurus from Europe and Massospondylus from southern Africa are among the best known, found as whole skeletons and, for Massospondylus, nests of eggs with embryos inside.
