McKenna and Bell recognized two subfamilies (Plesiadapinae and Saxonellinae) and one unassigned genus ("Pandemonium") within Plesiadapidae. More recently "
Saxonella " (the only saxonelline) and "Pandemonium" have been excluded from the family,cite journal | author = Silcox, M.T., Krause, D.W., Maas, M.C., and Fox, R.C. | year = 2001 | title = New specimens of "Elphidotarsius russelli" (Mammalia, ?Primates, Carpolestidae) and a revision of plesiadapoid relationships | journal = Journal of Vertebrate Paleontology | volume = 21 | issue = 1 | pages = 132–152 | doi = 10.1671/0272-4634(2001)021 [0132:NSOERM] 2.0.CO;2 | doilabel = 10.1671/0272-4634(2001)021[0132:NSOERM]2.0.CO;2] leaving only a redundant Plesiadapinae. Within the family, "Pronothodectes " is the likely ancestor of all other genera, while "Plesiadapis " may be directly ancestral to both "Chiromyoides " and "Platychoerops ".References
