Abstract
The Ngorora Formation occurs within a long sequence of stratigraphic units that are firmly calibrated by 40K/40Ar dates. It contains an impressive fauna and has yielded a valuable amount of information on local palaeoenvironments and on the sedimentary processes operative during its deposition. Here, a previously unpublished vertebrate and invertebrate faunal assemblage between 9 and 12 Myr old is recorded, and the stratigraphic framework of this former gap in the fossil mammalian record of Africa south of the Sahara is described.
