Recently Recovered Specimens of North American Eocene Omomyids and Adapids and Their Bearing on Debates about Anthropoid Origins

Part of the Advances in Primatology book series (AIPR)


Most recent reviews of primate evolution recognize that modern primates can be divided into two monophyletic suborders, the Strepsirhini (lemuriforms and lorisiforms) and the Haplorhini (tarsiers, monkeys, apes, and humans). It is also accepted by most researchers that the radiation of modern primate taxa dates to at least the beginning of the Eocene. The earliest occurring animals that appear to be seeded within this radiation belong to the families Adapidae and Omomyidae, the Eocene euprimates (Hoffstetter, 1974; Szalay and Del-son, 1979; Covert, 1986; MacPhee and Cartmill, 1986; Martin, 1986; Wible and Covert, 1987; and Szalay et al., 1987).
