Geography
Country: South Africa

State: Northern Cape


Coordinate: 27° 50' 42" S, 23° 33' 14" E
Coordinate basis: based on nearby landmark

Time interval: Middle Pleistocene

Max Ma: 0.238

Min Ma: 0.153

Age basis: OSL

Geography comments: "between the towns of Danielskuil and Kuruman" (coordinate given by Wikipedia)
there are four OSL dates on the stratum ranging from 238 +/- 13 to 153 +/- 15 kyr and four U/Th dates, the two precise ones being 97 +/- 3 and 168 +/- 14 kyr; the authors appear to favour the OSL dates

Environment
Lithology: sandstone

Taphonomic context: carnivore accumulation,cave,human accumulation,rodent accumulation

Archaeology: stone tools

Habitat comments: "This layer is 18 cm thick, composed of dark tan sand, locally laminated and locally discolored to black or off-white... It contains rare light-gray rounded gravel" and there was "a nearby body of water or seasonally dry lake" that provided the sediments
"many bones in the assemblage are burnt... and/or have been modified by carnivore and porcupine damage... copious quantities of hyaena coprolites were found" so carnivores "may have served as vectors for the introduction of some prey species into the cave" and it is fair to infer this is also a porcupine accumulation, although the authors take no position
the lithic assemblage "consists of 132 detached pieces" and the faunal assemblage "reflects of a range of subsistence activities including trapping of small reptiles and mammals" and "hunting" of larger ones
