Geography comments: "Jinsitai Cave is located in the low foothills of the Donghaierhan Mountains, 25 km west of the town of Alatanheli in Inner Mongolia, northern China".
"For Layer 8, AMS radiocarbon dating was conducted on one charcoal and six bone samples. The dates from bone samples treated by ultrafiltration yielded uncalibrated ages of 41,820 ± 840 BP and 39,320 ± 610 BP, with an inferred age range of 47,034 to 42,306 cal. BP".

Environment
Lithology: siliciclastic (mixed)
Taphonomic context: cave,human accumulation
Archaeology: stone tools
Habitat comments: "Jinsitai cave, which is around 120 m2 in area, is situated in a granite hill. Nine clear stratigraphic layers were identified and exposed over a depth of approximately 3.6 m. The sediments are composed mainly of yellow-brown gravels, clayey silt, clay, and silty sand with granite breccia".
"A total of 720 lithic artefacts were found during the 2012–2013 excavations in layer 7 (231) and layer 8 (489). The lithic assemblages from these layers contain a range of artifacts, including cores, flakes, and as many as 93 modified tools and 18 tool fragments". These artefacts "closely resemble the Mousterian industries of central and western Eurasia".

Methods
Life forms: ungulates
Sampling methods: quarry
Sample size: 8 specimens
Years: 2012 - 2013
Sampling comments: "The Jinsitai Cave was first excavated in 2000–2001, although these initial excavations were not well controlled and the lithic assemblages were not properly described". The site was thus reinvestigated in 2012–2013".
"The 2012–2013 excavations covered a maximum area of 10 m2". No further excavation details are provided.
"The preservation of bone is quite poor in the area sampled; only 150 vertebrate remains were piece-plotted from layers 7–8".
