Recent and ongoing research on the dinosaurs of the Early Jurassic Hanson Formation of the central Transantarctic Mountains is summarized here. Cryolophosaurus ellioti belongs to a geographically widespread clade of medium-bodied, Early Jurassic theropods, while the Antarctic sauropodomorph represents a new taxon that is a member of the similarly diverse and widespread Massospondylidae. The phylogenetic relationships of the Antarctic dinosaurs are consistent with a pattern of extreme faunal homogeneity between Early Jurassic continental biotas. Furthermore, these analyses support a “ladder-like” arrangement for basal theropod and basal sauropodomorph phylogeny, suggesting that these groups passed through “coelophysoid” and “prosauropod” stages of morphological organization early in their respective evolutionary histories. Future exploration and collection in the Hanson Formation and underlying Falla Formation will be critical to testing phylogenetic and biogeographic patterns involving the Antarctic dinosaurs, and the Antarctic fauna as a whole.
