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. Allain and N. Aquesbi 2008Two of these synapomorphies are non-homoplastic: the strongly transversely flattened tibial shaft and the marked dorsoventral flattening of the unguals of pedal digits II and III. The three other synapomorphies are homoplastic, they are: the presence of a lesser trochanter on the femur (reversal), the great breadth of the distal end of the tibia (convergently acquired by Titanosauria) and the posterior extension of the ascending process of the astragalus (convergently acquired by Neosauropoda).
