The Mogushanbei site is located at the northern edge of a hill called Mogushan in Zhalainuoer District, Hulunbeier City, Inner Mongolia. The site, discovered in 1980, with many chipped stone artifacts collected that year and again in 1990. The site was reinvestigated in August 2019, with about 400 chipped stone artifacts collected from the surface and from the uppermost breccia layer of three test pits. Artifacts were made of local andesite from Mogushan hill. The lithic assemblage includes cores, flakes, chunks, and retouched pieces, with artifact size being relatively large, however many small flakes were also found in test pit 3 (and not from surface explorations). Preliminary analysis of the technology, suggests the assemblage resembles a simple core-flake technology in North China, and is Late Paleolithic.
