Hemiacodon is a genus of early Eocene omomyid from North America.

Description

Hemiacodon is known from mainly dentary material, and the various species are differentiated by the shape and development of shearing crests on the molar. This variation in molar shape indicates the different species had varied diets.

Paleoecology

Hemiacodon lived alongside many other primates in western North America, including Pelycodus, Notharctus and Macrotarsius. Older literature speculates that the diversity of primates in early Eocene California was caused by them being temporary "safe havens", meaning the environment was more accommodating than surrounding areas.
