     "abstract": "The Hanson Formation of the Central Transantarctic Mountains has yielded a diverse Early Jurassic\nterrestrial fauna, which includes the nearly complete theropod dinosaur, Cryolophosaurus ellioti, and a fragmentary\nbasal sauropodomorph dinosaur. The Hanson Formation dinosaurs are important for understanding early dinosaur\nevolution because: 1) they preserve a mosaic of morphological traits that render them useful for interpreting poorly\nknown parts of the dinosaur evolutionary tree; 2) they are from the Early Jurassic, a critical period in early dinosaur\nevolution about which knowledge is scant; and 3) they are the only known Early Jurassic dinosaurs from Antarctica,\nmaking them particularly valuable for understanding patterns of biotic interchange during this time. Recent research\nsuggests that Cryolophosaurus belongs to a geographically widespread clade of mid-sized, Early Jurassic theropods\nwith cranial crests that includes Dilophosaurus wetherilli, \u2018Dilophosaurus\u2019 sinensis, and Dracovenator, and renders\nCoelophysoidea sensu lato non-monophyletic. The Antarctic sauropodomorph represents a distinct taxon that is a\nmember of a similarly diverse massospondylid clade. This taxon shares a number of features with more derived\nsauropodomorphs, and provides additional evidence for the paraphyly of Prosauropoda. The phylogenetic relationships\nof the Antarctic dinosaurs are also consistent with a pattern of worldwide faunal homogeneity between Early Jurassic\ncontinental biotas. Furthermore, these analyses support a \u201cladder-like\u201d arrangement for basal theropod and basal\nsauropodomorph phylogeny, suggesting that these groups passed through \u201ccoelophysoid\u201d and \u201cprosauropod\u201d stages of\nmorphological organization early in their respective evolutionary histories.",
