Abstract: Fifty-two stone artifacts were collected from loessic sediment at the Beishan site, Hunchun County,Jilin Province, and they include cores, flakes, blades and tools made on flakes. Scrapers, points and a broken spear head are recognized. Obsidian is the major raw material, constituting 86. 5 % of the assemblage. According to the characteristics of these artifacts, the stratum from which the artifacts were, and the fact that no polish stone tools and pottery sherds were found with them,we suggest that the site is probably in the late period of the Late Pleistocene or of the Late Palaeolithic.
