Glacialisaurus hammeri

Only known from a partial hind limb and foot, this prosauropod from of Antarctica shows that primitive forms such as Glacialisaurus lived alongside more derived sauropodomorphs in the Early Jurassic. A phylogenetic analysis shows it is most closely related to the Chinese Lufengosaurus.
