Geography comments: "Mezmaiskaya Cave is located in the northwestern foothills of the Caucasus Mountains, approximately 50 km south of the city of Maikop in the Azish-Tau Range, which is part of the Lagonak Upland. The site overlooks the right bank of the Sukhoi Kurdzhips (a small tributary of the Kurdzhips River), and lies at an elevation of 1300–1350 m"
"Layer 2B yielded a conventional AMS radiocarbon date on bone of 40,660 ± 1600 BP"
JA: there are mean ESR dates on teeth from this layer ranging from 36.6 ± 3.0 ka (early uptake) to 70.6 ± 7.4 ka (late uptake) (Skinner et al. 2005)

Environment
Lithology: claystone

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

Archaeology: stone tools

Habitat comments: "Mezmaiskaya Cave contains a deep succession of rubble and clay deposits that span much of the Late Pleistocene". Layer 2B consists of "brown silt loam and silty clay loam with small to large angular rock fragments and numerous small rounded pebbles. Layers 2, 2A, 2B, and 3 yielded hundreds of Mousterian artefacts. The assemblages contain few cores and a high proportion of tools. In the lower levels (Layers 2B and 3), bifacial implements, including small triangular hand axes, bifacial side-scrapers and points, are relatively common, although the majority of tools comprise unifacial sidescrapers".
"Most of the faunal remains were deposited through biotic processes; they represent animals that either inhabited the cave or were brought to the cave by its inhabitants. The large quantity of microvertebrate remains were likely accumulated primarily by owls. Some of the macrovertebrate remains probably represent the prey of carnivores (particularly leopard). However, the bulk of the medium and large mammal remains in the Mousterian occupation layers match the characteristics of an assemblage accumulated by human hunters".

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

Sampling methods: quarry,screenwash

Sample size: 3351 specimens

Years: 1987 - 1994

Sampling comments: "Excavations at the cave were conducted during 1987–1994, exposing a total area of approximately 30 m2".
"Cave sediment was excavated by natural stratigraphic layer (subdivided by 5 cm levels) with small knives, and water-sieved (mesh sizes of 3 and 1 mm)".
