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
J. F. Bonaparte and R. A. Coria 1993Sauropods with small pleurocoels located in the anterior sector of an ovoid depression, anteroposteriorly lengthened, located in the upper half and middle-anterior of the vertebral body; lateral face of the inferior half of the neural arch with two or more well defined, deep and angular depressions. (Translated by M. C. Lamanna.)
L. Salgado et al. 1997Eye-shaped pleurocoels in trunk vertebrae. Posterior trunk vertebrae with ventrally widened, slightly forked infradiapophyseal laminae. Presence of centro-parapophyseal lamina in posterior trunk vertebrae. Anterior caudals procoelous. Pubic considerably longer than ischium.
