The Lukeino Formation occurs within a long sequence of Neogene sedimentary units that are soundly calibrated by K−Ar dates. It has yielded an abundant and varied fauna and flora, and contains a wealth of information on palaeoenvironments and sedimentary processes occurring during its deposition. Previously unpublished vertebrate and invertebrate assemblages, about 6.5 Myr old, are recorded here, and the stratigraphic and sedimentary framework of the formation is established.
