If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
|P. M. Galton 2007||autapomorphies : deltopectoral crest symmetrical in lateral view with the gently rounded apex at 25 % (measured perpendicular to long axis of humerus) of humeral length, manus with lateral reduction so phalangeal formula 2-3-4-2-1, distally the thickest parts of the ischia are separated by a cleft that is Λ-shaped in dorsal view ; plesiomorphies : low deltopectoral crest (also in Pantydraco caducus but apex asymmetrical at 40 % of humeral length) with large medial tubercle adjacent to head (also in most basal sauropodomorphs, small in P. caducus), distal tarsal I transversely narrower than metatarsal I (occurs in no other basal sauropodomorph) and transversely narrow metacarpals I (and phalanx 1, also in Efraasia minor) and II-IV (also in E. minor and Anchisaurus polyzelus).|
