Geography comments: "Tham Lod rockshelter is located in the Tham Lod Nature and Wildlife Educational Center in northern Thailand, approximately 640 m above sea level, and 250 m from the Lang River".
Based on several radiocarbon ages, "the middle part of the sequence (Unit 2) is dated to between 13,640 and 22,257 years BP".

Environment
Lithology: not described
Taphonomic context: human accumulation,rock shelter
Archaeology: stone tools
Habitat comments: "The rockshelter forms part of a huge semi-circular karstic limestone doline, facing to the north. The karstic features are developed in Middle Carboniferous limestones".
"Based on the stratigraphic profile and chronological data, the sequence is divided into three main geoarchaeological units or "Cultural Layers" that can be correlated to the successive settlement phases". The second cultural layer (Unit 2), the middle part of the sequence, "can be related to the second settlement phase, during which the site could have experienced a break in its occupation".
"The Tham Lod lithic assemblage involved a total of 102,386 items recovered from all three cultural layers. These can be subdivided into cores, flake tools, and pebbles, with the majority being produced from locally available grey sandstone cobbles and pebbles collected from the nearby Lang River". The site "appears to have been used as a lithic workshop (tool manufacturing and maintenance), as supported by the high densities of lithic artifacts and refuse".

Sampling methods: quarry,screenwash
Sample size: 639 specimens
Years: 2002
Sampling comments: "In 2002, the Highland Archaeology Project excavated three areas at the base of the rockshelter, covering a transect from the cliff slope to the lower plain: Area 1 (a 6 m2 trench), Area 2 (a 12 m2 trench), and Area 3 (an 18 m2 trench)".
The register below corresponds to the remains found throughout Cultural Layer 2.1 (Unit 2) across all three excavation areas.
