Buluk (Miocene of Kenya)

Where: Kenya (4.3° N, 36.6° E: paleocoordinates 3.0° N, 34.1° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Buluk Member (Bakate Formation), Early/Lower Miocene (23.0 - 16.0 Ma)

• "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

• group of beds-level stratigraphic resolution

Environment/lithology: coarse channel fill; claystone and coarse-grained sandstone

• "fossils are found almost exclusively in the channel deposits and are often associated with silicified wood"
• "coarse silt" (Harris and Watkins 1974) or "claystones with coarse sandstone and conglomerate channel fills" (Leakey and Walker 1985)

Size class: macrofossils

Collection methods: includes significant new collections made in 1983 and not previously reported
