Micromomyidae

Family of archaic fossil mammals belonging to the order Plesiadapiformes; known from the late Paleocene to the early Eocene of North America; four genera. Vernacular: micromomyid. These are the smallest plesiadapiforms, ranging in size from 10 to 30 g. Dental formula appears to be 2.1.2.3/2.1.2.3; procumbent incisors, enlarged upper and lower fourth premolars; teeth and small body size suggest that these forms practised insectivory.
