Abstract

The results of excavations at Songhor in 1972–73 and at Koru in 1978–80 are described. An account is given of the geology of the localities and the attempt is made to correlate these and other exposures in the Tinderet region of western Kenya. The oldest beds were excavated at a new site near Muhoroni called Meswa Bridge in river channel deposits of the Muhoroni Agglomerates. Succeeding formations are named the Koru Formation, Legetet Formation, and Kapurtay Agglomerates, all fossiliferous. The Kapurtay Agglomerates in the Koru area outcrop mainly in the Chamtwara Valley, and these beds are correlated with the Songhor deposits on the basis of a sequence of Augite Nephelinite Agglomerates common to both. The vertebrate fossils are found in terrestrial deposits (except at Meswa Bridge in the Muhoroni Agglomerates) and are usually associated with palaeosol development. The faunas have highly diverse small mammals but more limited large mammals (again except at Meswa Bridge), suggesting the existence of selective factors operating either in bone accumulation or during deposition. There may have been a combination of selection by carnivores and size sorting during deposition.
