Environment
Lithology: not described
Taphonomic context: bird accumulation,carnivore accumulation,cave,human accumulation
Archaeology: bone tools,stone tools,other artifacts
Habitat comments: "Bone accumulation in the Khayrgas Cave was most likely due to the activity of predatory mammals (cave lion, wolf, red fox, ermine), birds of prey (eagle-owl), and humans".
"From Layer 7, 705 stone artifacts and 20 bone artifacts were recovered. The stone assemblage includes mostly wedge-shaped cores, blades, scrapers, and numerous flakes. Bone items are represented mainly by inset points and arrowheads".

Methods
Life forms: carnivores,rodents,ungulates,other small mammals
Sampling methods: quarry
Sample size: 16 specimens
Years: 1998 - 1999
Sampling comments: "Khayrgas Cave was found and initially excavated in 1984–1985, and was continued in 1998–1999, with a total of 103 m2 unearthed. About 17,000 bones have been found at the site in total, although only a small fraction (6%) can be identified".
The species counts below pertain to the identified remains uncovered from Layer 7 of the 1998–1999 excavation pit. The remains from the 1985 pit are omitted as there is evidence suggesting a high degree of intermixing between layers.
