Excerpt from The Carpolestidae: Early Tertiary Primates From North America Simpson listed the enlarged lower fourth premolar and the procumbent enlarged lower incisor. The dental formula remained controversial, however. Jepsen (1930) had proposed the mandibular dental formula regarding the tooth immediately behind the enlarged incisor as P1. Simpson although conceding that it was impossible to determine whether the fol lowing tooth is a canine or P1 considered it slightly more probable that it is the canine. Discussing the degree of relation ship among the three genera, Simpson (1937bzl61) remarked that the morphologic sequence elphidotarsius-carpodaptes-car polestes may be a direct phylogeny, al though the possible age difference between the last two genera seems too small to per mit such a marked structural advance in a direct descendant, and it is more likely that some collateral evolution is involved.
