Diagnosis

---|---|---|
B. W. McPhee et al. 2014 | Sauropodiformes as defined here is diagnosed by: the lack of an elongate median nasal impression (autapomorphically present in Melanorosaurus); mesial and distal serrations on the carinae of the maxillary and dentary teeth; absence of laterally expanded tables at the mid-length of the dorsal surface of the dorsal neural spines; posterior margin of the middle dorsal neural spines straight in lateral view; sacral rib not significantly narrower than the trans- verse process of the first primordial sacral vertebra; length of the manus less than 38% of the humerus + radius (reversed in Anchisaurus Marsh, 1885); absence of a posteriorly projecting ‘heel’ at the end of ischial peduncle of the ilium (convergently absent in some specimens of Massospondylus); absence of a well-developed brevis fossa (also present in Lufengosaurus Young, 1941); rounded posteromedial process of distal tarsal IV in proximal aspect; and a first metatarsal that is at least the same width proximally as the second metatarsal (present also in Lufengosaurus and Glacialisaurus Smith & Pol, 2007). |
