Abstract

Two new species of Orycteropus are described from Miocene deposits of Kenya. O. minutus, sp.nov. the smallest known orycteropodid is recorded from the lower Miocene of Songhor, Rusinga and Mfwangano. O. chemeldoi sp.nov. is known from the mid-Miocene of Ngorora and Fort Ternan. Additional material of O. africanus (MacInnes) is described and parts of three specimens of O. afer crassidens (MacInnes) are described from the lower Pleistocene of East Rudolf. A review of fossil Orycteropodidae is given, and maps and diagrams presented which show all the recorded localities which have yielded Orycteropus. The Eurasian species are considered to form a closely related group which lived there from about 9 million until about 5 million years ago, in which case they may represent a good key group for stratigraphic purposes.
