Abstract: Baifeng Paleolithic site was discovered at Tianyang County,Guangxi in 2009. It is located on the fourth terrace of the right side of the Youjiang River; its geographical position is 23° 45.399'N, 106° 43.636'E. During the survey, 27 stone artifacts were gathered from the surface, including cores(N=3), flakes(N=2), picks(N=14), choppers(N=5) and scrapers(N=3). Lithic raw materials were locally available from ancient riverbeds including quartzite(33%), argillite(22%), quartz(19%), farina sandstone(19%) and breccia(18.82%). Tool blanks were mostly pebbles as only two pick blanks were flakes. Most of the stone artifacts were large or medium in size, and modified by direct hammer percussion. According to typological analysis of these stone artifacts along with comparison to geomorphological and chronological details with other sites of the Baise Basin, we suggest that this site should date to the early Middle Pleistocene.
