Songhor (1989-1990 collections) (Miocene of Kenya)

Where: Kenya (0.1° S, 35.2° E: paleocoordinates 1.2° S, 33.1° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Redbeds Member, Burdigalian (20.4 - 16.0 Ma)

• the member "consists of ten beds of volcanic material dated to younger than 19.9 +/- 0.6 Ma" (i.e., Burdigalian)

• member-level stratigraphic resolution

Environment/lithology: terrestrial; lithology not reported

Size class: macrofossils

Collected in 1986, 1989, 1990

Collection methods: bulk, quarrying, surface (float), sieve

• "About 200 tons of sediment were excavated from an area 10 x 4 m... and wet-screened in a nearby river. The remaining areas of the exposures were surveyed, swept and dry-screened... 1100 fossils are from screening and 36 from prospecting"
