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.
|F. J. Goin et al. 1999||Family Microbiotheriidae. The upper molars have a very reduced stylar shelf and cusps. The protocone is strong; the paracone and metacone are subequal in size and height. The preparacrista is very short and connected with the parastylar corner. The lower molars have a metaconid slightly displaced posteriorly, especially on ml-2. The anterior cingu- lum is vestigial or absent. The talonids are wide. The hypoconulid is small and not close to the entoconid but relatively separated from it.|
