Sauropodomorpha
Sauropoda includes all the big long-necked four limbed plant-eating dinosaurs that thrived during the Jurassic period. These creatures did not have the chewing ability of the Cretaceous Ornithopoda, so they relied on very long guts to digest their foot. As a result, they grew to a massive size. They decended from the Prosauropods. These earlier long-necked creatures evolved in the Triassic era, and walked on either two of four limbs.

| Melanorosaurus was a Prosauropod, an early ancestor of the Sauropods. It walked on all fours, unlike the earlier Plateosaurus which could walk on its hind legs. Not a great deal more is known about these earliest sauropodomorpha as only a few limb bones and vertabra have been uncovered. |
