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. Navarrete et al. 2011Large sized titanosaurid characterized for the following associated characters: (i) occurrence in the anterior dorsal vertebrae, of two robust spinodiapophyseal laminae, one anterior and other posterior, which delimit an elongate and deep supradiapophyseal cavity; (ii) presence in the anterior dorsal vertebra of a small circumneural lamina surrounding the neural canal in posterior view; (iii) the last sacral vertebra with postspinal lamina expanded toward the neural spine apex; (iv) prespinal laminae, at least until 5º? caudal vertebra, expanded toward the neural spine apex; (v) existence in the anterior caudal vertebrae of tuberopostzygapophyseal laminae; (vi) presence of ventral foramina, at least until the 4º? caudal vertebrae; and (vii) prezygapophyseal tuberosity jointed the prespinal lamina until the 4º? caudal vertebrae.
