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
S. J. Nesbitt et al. 2017Aphanosauria differs from all other archosaurs in possessing the following unique combination of character states: elongate cervical vertebrae with epipophyses and anteriorly overhanging neural spines that have rugose lateral margins on their dorsal ends; elongated deltopectoral crest that is at least 35% the length of the humerus; wide distal end of the humerus; femur with a scar for the M. iliofemoralis externus near the proximal surface (homologous with the anterior trochanter in dinosauromorphs) that is separate from the scar for the M. iliotrochantericus caudalis (homologous with the trochanteric shelf in dino- sauromorphs), without an anteromedial tuber, and with a straight, deep groove in the proximal surface; calcaneal tuber taller than broad (see Supplementary Information).
