No recent information is available from the other places where both forms are known to be sympatric and from where hybrids were recorded. The earliest fossil record of Kobus ellipsiprymnus is from the early Pleistocene of East Africa from faunal zones A and B of the eastern Lake Turkana basin (age about — million years) and of about the same age from the Omo Sequence, southern Ethiopia, and Olduvai Gorge, Tanzania (Gentry 1976, 1978, Harris 1976). In the respective faunal zones from Lake Turkana Reduncini {Kobus, Reduncd) are the most numerous bovids, indicating mesic conditions during that period. So, already in the beginning of its existence waterbuck had.
