Abstract: The Gaolingpo Paleolithic site is located on the fourth terrace of southern bank of the Youjiang River in the Bose (Baise) Basin, Tanhe County, Guangxi Zhuang Autonomous Region. A total of 834 stone artifacts stored in the IVPP were observed and measured, and can be classified into manuports, cores, flakes, chunks and retouched pieces. Both flakes and chunks are largest in number. Tools include heavy duty tools and light duty tools. The former part has handaxes, picks and choppers and the latter part has scrapers, notches, becs, and awls. Different blanks and raw materials were chosen to make different tools. Direct hammer percussion is the principal flaking technique. Most flaking work happened from the flat surface to the convex, but alternating, bifacial shaping or retouching on tools also occurred.
