Tinimomys Graybulliensis Szalay, 1974

Archaic mammal known from the early Eocene of North America belonging to the Plesiadapiformes family Micromomyidae; monotypic. Dental formula probably 2.1.2.3/2.1.3.3; small body size strongly suggestive of insectivory; unique among mammals related to primates in that the fourth upper premolar is semimolarized; however, other traits clearly indicate this is a plesiadapiform. Body size of the species very small; estimated at 15 g. It has been suggested that Tinimomys was a gliding mammal.
