Abstract: This paper is a preliminary report of the excavation and study of stone artifacts from work at the Gaolingpo site of Baise ( Bose) Basin in 1993. From an area of 40㎡, totally 445 stone artifacts were collected together with some tektites. The majority of artifacts are flakes and chunks except for some formal tools and manuports. There are various types of choppers and also becs, which is the second most prominent tools after those from the Fengshudao site in Baise Basin. The character of flakes shows a high degree of complex working. The large proportion of flakes and chunks reveals that the excavated area was a stone tool － making workshop. These knapped flakes and debris may have close relationship with conventional tool types like handaxes, picks and chopper, etc. from other Paleolithic sites in the basin. New types of choppers and flake tools like becs indicate the potential of future research of the Baise Paleolithic industry.
