Geography
Country: Russia
Coordinate: 53° 2' N, 56° 26' E
Latlng basis: stated in text
Time interval: Late Pleistocene
Geography comments: "The Imanay Cave is located in a mountainous region in the Southern Urals".
Although there are several radiocarbon dates on cave bear and cave lion remains (all from Layer 1; 46 to 26 ka), the entire faunal complex likely accumulated over the entire Late Pleistocene.

Environment
Lithology: sandstone
Taphonomic context: cave
Archaeology: stone tools
Habitat comments: "The Imanay Cave was formed in grey dolomite limestone of the Kungurian stage of the Lower Permian. In total, four lithological layers were detected during the excavation. Palaeolithic stone tools were found in Layer 1, although there is no convincing evidence that the accumulation of remains was related to human activity. Instead, the bones likley emerged as a result of natural mortality of the animals".
Methods
Life forms: carnivores, rodents, ungulates, other small mammals
Sampling methods: quarry, screenwash
Sample size: 1342 specimens
Net or trap nights: 0
Basal area status: not applicable
Sampling comments: "A 6 m2 excavation unit was placed in the inner part of the cave. More than 10, 000 animal bone specimens were excavated from the 12 m3 deposits. The deposits were excavated in 10 cm horizons. All sediments were rinsed in water and sieved using 0.5 and 1.0 mm mesh".
