Geography comments: "Ban Rai rockshelter is situated on the southern edge of a steep-side river valley, about 2–3 km to the west of the nearest village, Ban Rai, at an elevation of approximately 740–760 m above sea level and 200 m from the present-day location of the Lang River".
Radiocarbon dates for the excavated layers range from 10,600 BP to 7,250 BP.

Environment
Lithology: not described

Taphonomic context: human accumulation,rock shelter,settlement

Archaeology: burials,stone tools

Habitat comments: "The site is located near the summit of a Lower Carboniferous limestone valley and is a circular sinkhole, 105 × 142 m across. The surface of the rockshelter has evidence of a large rock fall and the presence of log coffins, while the eastern wall exhibits rock paintings".
The stratigraphic profile can be characterized by a sequence of two successive settlement phases. The first (Unit 1), represented by the lower part of the sequence, contains no faunal remains nor any lithic assemblages. The second (Unit 2), the upper part of the sequence, "yielded the remains of a human burial and settlement". The lithic assemblage here consists of at least 9,800 items, which include "sumatraliths, short axes, waisted cores and flakes, and utilized cores and flakes".

Methods
Life forms: carnivores,primates,rodents,ungulates,other large mammals,birds,lizards,turtles,fishes

Sampling methods: quarry,screenwash

Sample size: 282 specimens

Years: 2001

Sampling comments: "In 2001, the Highland Archaeology Project selected three areas for excavation, from the center of the rockshelter to the eastern wall: Area 1 (28 m2 trench), Area 2 (24 m2 trench) and Area 3 (16 m2 trench). The largest number of excavated finds originates from Area 3, while Area 1 and Area 2 have far lower densities".
The register below corresponds to the faunal remains uncovered from Area 3, the most recent area of the site, corresponding to the second cultural layer (Unit 2).
