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.
|K. Remes 2007||Diplodocid sauropod with cervical pleurocoel weakly developed; ridge posterolateral to anterior condyle strongly posteroventrally inclined; anteriorly facing triangular pneumatic cavity ventral to prezygapophysis, enclosed by the lateral ramus of the centroprezygapophyseal lamina and an anteriorly extended prezygodiapophyseal lamina; prominent prezygapophyseal process pointed, laterally keeled and reaching further anterior than the prezygapophysis. Additionally, Australodocus differs from other diplodocids in the combination of following traits: mid-cervical centra moderately elongate (Elongation Index < 4Æ1); pleurocentral lamina widened to form a shelf; parapophyses broad and robust; neural arch deep relative to centrum height; lateral ramus of centroprezygapophyseal lamina pillar-like.|
|J. A. Whitlock 2011||Titanosauriform sauropod characterized by the following combination of characters: bifurcate mid-cervical neural spines, a robust accessory anterior process of the prezygapophysis, and an anteroventral expansion of the prezygapophyseal–diapophyseal lamina (prdl) in mid-cervical vertebrae, enclosing the lateral margin of an anteriorly-facing, triangular cavity beneath the prezygapophysis.|
