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
M. Morlo et al. 2004Barbourofelidae are distinguished by the following: loss of P1/, M2/, P/1 and M/2; plesiomorphic tooth formula 3131/3131; apomorphic species additionally lose P2/ and P/2; scimitar-like sabreteeth with crenulations on, at least, the posterior border of upper canines; upper canines markedly compressed with vertical grooves present; strong relationships between the eruption of the upper canines and the development of other sabretooth features, especially the mandibular flange (see Peigné & de Bonis, 2003); no anterior cusp on P/3, but distinct and sometimes large posterior accessory cusp on P/3-4; protoconid of M/1 relatively tall (at least in early taxa); talonid of M/1 extremely reduced, and markedly more so than the metaconid; reduction of the talonid before the metaconid on M/1; angular chin on mandible (genial flange in the apomorphic genera) and slightly (Afrosmilus turkanae) to strongly (other taxa) curved mandibular body; short horizontal proseptum in the anteromedial corner of the auditory bulla; early and complete fusion of elements making up the bulla. In addition to those features, the Barbourofelidae differ from the Nimravidae (primitive taxa) by the following: fully ossified bulla invading the mastoid; thin wall of the caudal entotympanic, not composed of three layers as in Nimravidae; petrosal not deeply recessed in the basicranium; absence of the postglenoid foramen; presence of a parastyle on P4/; protocone on P4/located further back; bulla more anteriorly located (than in the most primitive felid genera such as Proailurus and Pseudaelurus) and consequently a more anteriorly placed foramen ovale which is close to the posterior opening of the alisphenoid canal (except Barbourofelis); a shortened palate; lateral walls of the nasopharynx converging posteriorly; broad metacarpals (known from Sansanosmilus palmidens and Barbourofelis fricki only).
