Reference: S. Stanc, A.-D. Stanica, L. Bejenaru, and M. Danu. 2021. Archaeological animal remains from Noviodunum fortress. International Journal of Conservation Science 12(1):195-204 [ER 3952]
Geography
Country: South Africa

State: Western Cape

Coordinate: 34° 39' 50" S, 18° 26' 43" E
Latlng basis: based on nearby landmark

Time interval: Middle Pleistocene

Unit number: 3

Unit order: above to below

Min Ma: 0.29

Age basis: OSL

Geography comments: "on the property of the Koeberg Nature Reserve, adjacent to the Koeberg Nuclear Power Station, about 35 km north of Cape Town" (coordinate based on Koeberg Nature Reserve)
dating was buy a "tedious sub-technique" of OSL "known informally as the 'subtraction method'"
a date of "roughly 290 ky" is for sediment "betwen Horizons 2 and 3", so it is a minimum
the entire site is thought to be Late Acheulean and therefore Middle Pleistocene

Environment
Lithology: sandstone

Taphonomic context: aeolian deposit

Archaeology: stone tools, other artifacts

Habitat comments: "stratified within a 10-m thick dune plume" and specifically a "paleosurface" that is "110-120 cm from the present surface" and like Horizon 2 represents the margin of "a large interdunal marsh or pond"
the lithology is "fine white drift sands"
there is no direct discussion of the taphonomy of Horizon 3, so the accumulation agent is unclear
it it not clear from the text whether any stone artefacts are present in Horizon 3, but it is strongly implied that they are, and there is a "humanly introduced lump of red ochreous pigment (hematite)"

Methods
Life forms: carnivores, ungulates, other small mammals, birds

Sampling methods: quarry

Sample size: 96 specimens

Years: 1975, 1997 - 2001

Net or trap nights: 0

Basal area status: not applicable

Sampling comments: the initial excavations of Horizon 3 were in 1975, when it was discovered, and were resumed between 1997 and 2001
it is not clear whether micromammals, frogs, or tortoises are present in this layer
