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 2A yielded AMS radiocarbon dates on bone of 35,760 ± 400 BP and 36,280 ± 540 BP"
JA: there are mean ESR dates on three teeth from this layer of 40.8 ± 1.3 ka, which is reported both based on early uptake and late uptake models (perhaps by mistake) (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 2A consists of "dark reddish brown clay loam and clay with small to large angular rock fragments and 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 upper levels (Layers 2 and 2A), bifacial tools are rare, and side-scrapers are heavily predominant".
"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".

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)".
