Abstract: The Xibaimaying site is one of the most important Late Paleolithic sites in the Nihewan Basin. Eighty seven stone artifacts were collected from the anthropogenic layer of the site. The stone artifact assemblage can be classified into cores, debitage and retouched pieces. The debitage dominates the whole assemblage and comprise of whole flakes, broken flakes, flake fragments, and chunks. Chert dominates the raw material type, followed by quartz and siliceous dolomite. Most stone artifacts are small in size. The principal flaking technique at the site is direct hammer percussion followed by bipolar technique. Scraper is the tool type which was modified by direct hammer percussion. According to the new materials and the report on the excavation of Xibaimaying site in 1980s, the lithic technology of the site can be assigned to the small Flake Tool Tradition in North China.
