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.
|M. C. McKenna 1959||Primitive dichobunid artiodactyl in which the teeth are more bunodont than selenodont; the hypocone is retained on M1 and/or M2, the metaconules are large but are neither hypertrophied nor markedly displaced and, when unworn, possess five posterior crests; there is neither a mesostyle nor ectoloph ribbing on M1 and/or M2, strong diastemata isolate the double-rooted p2; p3 is trenchant and lacks a metaconid; p4 is also trenchant but possesses a distinct entoconid and a metaconid which separates from the protoconid high on the crown; m1 has a strong paraconid separated from the metaconid but not as widely separated as in Antiacodon or Auxontodon, m2 has a variably separated paraconid, and m3 has a fused single lingual trigonid cusp; all the lower molars are elongate, with hypo- conulids closely similar to those of Hexacodus.|
