Environment
Lithology: not described

Taphonomic context: human accumulation,settlement

Archaeology: ceramics,hearths,stone tools

Habitat comments: "The Wadh Lang’o site contains a well-stratified sequence of deposits extending back at least to the pre-ceramic Late Stone Age, with successive layers of Kansyore, Elmenteitan, Urewe, post-Urewe Middle Iron Age (MIA) wares, and historic Luo material, in each case associated with well preserved faunal assemblages".
The upper layers consist of a series of mixed ashy/loam deposits associated with Urewe and MIA ceramics.
In addition to ceramics, various stone tools including cores, microliths, scrapers and blades were also present. Numerous deep cut marks were observed on some bone fragments, as well as some evidence of burning.

Methods
Life forms: ungulates,fishes

Sampling methods: quarry,screenwash

Sample size: 164 specimens

Years: 2000-2004

Sampling comments: "During initial investigation, eight test-pits, mostly 1 × 1m, were excavated at various localities across the site".
In June and July 2001, a 5 × 5m trench was excavated a few metres upslope from Trench 5, and in 2004, a further two 2 × 2m test pits to the south-west and south-east of the main 2001 excavation were dug.
"All deposits were dry sieved through 5mm mesh sieves".
