Plesiadapidae is a family of plesiadapiform mammals related to primates known from the Paleocene and Eocene of North America, Europe, and Asia. Plesiadapids were abundant in the late Paleocene, and their fossils are often used to establish the ages of fossil faunas. ==Classification== 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, 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''.〔
