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.

Diagnosis
ReferenceDiagnosis
C.-C. Young and H. C. Chao 1972Extremely long cervical region (19 vertebrae); dorsal, sacral, and caudal vertebrae short and few in number (4 sacral vertebrae); massive and long cervical ribs; pleurocoels not well developed on dorsal vertebrae; anterior dorsal vertebrae with bifid neural spine; medial caudal vertebrae with bifurcated haemal spines; anterior caudal vertebrae procoelous; centrally positioned pubic peduncle on ilium.
S. Suteethorn et al. 2013Posterior cervical vertebrae of mamenchisaurids can be diagnosed by their bifid neural spine with a U−shaped cleft and no median tubercle; the centrum and neural spine are entirely filled with numerous small pneumatic camellae (cancellous inner structure); the centra show large pleurocoels with successive generations of smaller chambers.
