Geography comments: "Equus Cave is located on the Gaap Escarpment at Norlim (formerly Buxton), near Taung in the northern Cape Province (now North West) of South Africa".
"Two radiocarbon dates - 2390 +/- 60 yr B.P. (Pta-2452) on charcoal from near the middle of 1A and 7480 +/- 80 yr B.P. (Pta-2495) on ostrich eggshell from near its base - indicate that 1A dates from the Holocene".

Environment
Lithology: sandstone
Taphonomic context: cave,human accumulation
Archaeology: bone tools
Habitat comments: "Unit 1A ia a layer of grayish-brown sandy loam up to 50 cm thick. The entire sequence is rich in animal bones, and 1A also contains typical Later Stone Age bone points".
"The relative abundance of artifacts, the small number of porcupine gnawed bones, and the rarity of coprolites suggest that people were the main bone collectors in Unit 1A".

Methods
Life forms: carnivores,primates,rodents,ungulates,other large mammals,other small mammals
Sampling methods: quarry
Sample size: 828 specimens
Years: 1978, 1982
Sampling comments: "The first systematic excavations of Equus Cave took place in 1978 and were extended in 1982. A grid of squares 1 m on a side was laid down, and the excavation proceeded according to arbitrary 7.5-cm-deep levels or “spits” within four poorly defined natural stratigraphic units: lA, lB, 2A, and 2B".
