Small-bodied eutherian mammals with bunodont teeth from the Paleocene and Eocene have long been the subjects of taxonomic contention, with regard to both the assignment of individual genera to supergeneric clades (such as Hyopsodontidae, Pentacodontidae, and Dormaalidae) and to the place of those larger groups within Eutheria. Taxa traditionally placed in the family Hyopsodontidae have proven particularly problematic from the first standpoint, the clade has become a wastebasket for small-bodied, bunodont taxa whose morphology suggests affinities with the basal ungulate order Condylarthra (in this study, Ungulata and ungulate refer to the traditional morphological concept of this group, minimally including Artiodactyla, Perissodactyla, Hyracoidea, Proboscidea, Sirenia, and their extinct relatives, particularly condylarths and the South American ungulate radiation (e.g., McKenna and Bell, 1997); for visual simplicity, we use condylarth and Condylarthra without quotes, although we recognize that this group is likely para- or polyphyletic).
