The KANJERA exposures, on the low cliffs of the Homa Mountain close to Lake Victoria, consist of a tripartite series of basal greenish ash and tuffs, succeeded by clays with limestone and by upper transgressive beds of brown- greenish clay. Most of the fossils are obtained from and in close association with the lower tuff and ash layer, but it is not possible to be certain whether or not all the material came from this source (Kent, 1942). However, there is sufficient evidence that the Hipparion may be considered to be more ancient than the human fossil remains which were recovered from the middle beds. The Kanjera faunal beds are referred to the Middle Pleistocene, roughly contemporary with Olduvai IV. The LAKE EYASI beds are usually referred to an early Upper Pleistocene period, more on a palaeontological than on a geological basis. According to Reck and Kohl-Larsen (1936), it is probable that the Hipparion teeth recovered west and north of Mumba Hill, in the north-east section of the Eyasi basin (see p. 283), do not belong to the original beds. Indeed they are very much rolled, which is not the case for the presumably contem- poraneous material, and constitute a secondary deposition. If this interpretation is correct, these teeth are probably more ancient than the typical Eyasi fauna, and should be dated to a period prior to the Upper Pleistocene.
