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
R. M. Santucci and A. C. d. Arruda-Campos 2011Titanosaur characterized by the following unique association of characteristics: well-developed posterior protuberance below the articular area on the anterior and middle haemal arches and lateral bulge on the distal portion of the articular process of the mid-posterior haemal arches. An additional set of ambiguous synapomorphies includes: presence of posterior centrodiapophyseal lamina (pcdl) at least 50% thicker than the postzygodiapophyseal lamina (podl) in posterior cervical vertebrae; posterior dorsal vertebrae with intrapostzygapophyseal lamina and an oblique anterior centropostzygapophyseal lamina (acpol) which bifurcates from the proximal portion of the centropostzygapophyseal lamina (acpol); mid-thoracic ribs bearing well-developed anterior and posterior crests with a D-shaped cross section. These features are considered ambiguous because they cannot be assessed in other Aeolosaurus species so far, and may correspond to a set of synapomorphies of Aeolosaurus or even Aeolosaurini.
