Geography
Country: Russia
Coordinate: 53° 2' N, 56° 26' E
Coordinate basis: stated in text
Time interval: Holocene
Geography comments: "The Imanay Cave is located in a mountainous region in the Southern Urals".
There are no radiocarbon dates on any of the Holocene material; "it is likely most of those bones fell into the cave during the late Holocene".

Environment
Lithology: sandstone
Taphonomic context: carnivore accumulation,cave
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. High fragmentation of the bones and the observed signs of digestive
corrosion suggest that the accumulation of bones during the Holocene was a result of the activity of carnivorous mammals".

Methods
Life forms: carnivores,rodents,other small mammals
Sampling methods: quarry,screenwash
Sample size: 447 specimens
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".
