Like early prosauropods, the primitive sauropod dinosaur Barapasaurus has leaf-shaped, serrated teeth and, despite its name, quite slender limbs. More than 300 bones have been found and, together, they make up six incomplete skeletons. None of the skeletons has a skull or front or back feet. All the bones were discovered in the Early Jurassic rocks of the Godavari Valley in the Kota Region of southern India.
Compared with even the largest of the prosauropods. Barapasaurus was gigantic. Like most sauropods, it had a very long tail and a long neck probably supporting a small head. The individual bones that made up its spine had indentations in them, unlike the large hollows typical of more advanced sauropods such as Brachiosaurus. It is thought that these hollowed-out bones made the whole skeleton lighter ? useful for such huge animals. No one is sure how heavy Barapasaurus was, though, and estimates vary wildly from person to person. It lived on coastal flood plains or deltas, and fed on plants.
