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
| Reference | Diagnosis | |
|---|---|---|
| J. O. Calvo et al. 2007 | Slender Rinconsauria characterized by the following association of autapomorphies: basal tubera diverge 70 degree from each other; extensive, thin and concave medial lamina that unit basal tubera ventrally, basioccipital condyle wider than the proximal portion of the basal tubera; posterior dorsal neural spines with large prespinal lamina reinforced by two small accessory laminae, distal end of pubic blade rectangular and medially thick. In contrast to Rinconsaurus, Muyelensaurus gen. nov has anterior dorsals with neural spines posteriorly directed less than 45 degree with respect to the vertical, posterior dorsals with large and deep infradiapophyseal fossa and ventral face of posterior cervical centra narrow and strongly concave at level of the parapophysis. Moreover, different from Rinconsaurus, Muyelensurus gen. nov. lacks an accessory centroparapophyseal lamina in posterior dorsals, anterior caudals with postzygapophyseal process, and amphicoelous-biconvex or amphicoelous-opisthocoelous-biconvex caudal centra.
