The genusApidium (from Latin, a diminutive of the Egyptian bull god, Apis, as the first fossils were thought to be from a type of a cow) is that of at least three extinct primates living from the late Eocene to the early Oligocene, roughly 36 to 32 million years ago. Apidium fossils are common in the Fayoum deposits of Egypt. Fossils of the earlier species, Apidium moustafai, are rare; fossils of the later species Apidium phiomense are fairly common.
Apidium and its fellow members of the Parapithecidae family are stem anthropoids that possess all the hallmarks of modern Anthropoidea. Their ancestry is closely tied to the Eocene Asian group Eosimiidae.
