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. Owen 1861Teeth wanting, or limited to a single maxillary pair, having the form or proportions of tusks: a "foramen parietale;" two external nostrils; tympanic pedicle fixed; vertebrae biconcave; trunk-ribs long and curved, the anterior ones with a bifurcate head; sacrum of more than two vertebrae. Limbs ambulatory.
N. N. Rybczynski 2000Therapsids with preorbital lengths of 40% or less of total skull length; mandibular fenestra between dentary and angular; coronoid bone reduced or absent; zygomatic process rod-like and displaced dorsally; homodont dentition; teeth peg-like; dorsal part of quadratojugal expanded transversely; palatine extends further posteriorly than ectopterygoid; no pterygoid teeth.
C. F. Kammerer and K. D. Angielczyk 2009Only three phylogenetic analyses (Modesto et al. 1999; Fröbisch 2007; Fröbisch & Reisz 2008) have included Anomocephalus africanus, the most basal anomodont recognized to date, and we use these papers as sources of autapomorphies for Anomodontia. The most consistently cited autapomorphies of Anomodontia are: (1) serrations absent on marginal teeth; (2) mandibular fenestra present; (3) zygomatic arch bowed dorsally.
