Stratigraphy

Formation:	Bakate	Member:	Buluk
Stratigraphic resolution:	group of beds
Stratigraphy comments: "K/Ar dates on a basalt just above the fossiliferous sediments show that the fossils are older than 17.2 Myr" (Leakey and Walker 1985); fossils are from about 15 m within the ~50 m thick Buluk Member according to McDougall and Watkins 1985, who report a series of dates, of which one of 17.2 +/- 0.2 Ma for an immediately overlying basalt is favored

Includes fossils?	Y
Lithology description: "coarse silt" (Harris and Watkins 1974) or "claystones with coarse sandstone and conglomerate channel fills" (Leakey and Walker 1985)
Environment:	coarse channel fill
Geology comments: "fossils are found almost exclusively in the channel deposits and are often associated with silicified wood"
