Abstract:

The Dingmo site is located in Bubing Basin, Tiandong County, Baise City, Guangxi Zhuang Autonomous Region, south China. From 2010 to 2011, the Anthropology Museum of Guangxi and the Tiandong County Museum conducted a test-excavation at the Dingmo site, with a total area of 32 m2, and a total of 2108 stone artifacts were excavated and collected during this excavation. Besides, this excavation also yielded a few animal fossils. The Dingmo lithic assemblage consists of ground stone tools and cores, retouched tools, flakes, spilt flakes, chunks fragments and manuports. The majority of the retouched tools were chipped stone tools and the types of them are diverse, including choppers, scrapers, denticulates, notches and the tools’ blanks were mainly cobbles and flakes. Based on our raw material investigation, the utilized cobbles and pebbles at this site were most possibly collected from the nearby Youjiang River, sandstone-dominated. Freehand hard hammer percussion was exclusively used for core reduction, and the cores in this site appear to be simply worked and expedient. No preparations for the cores’ morphology and platforms were found among the core specimens excavated at the site. Additionally, the flakes predominantly exhibit simple morphologies and platform characteristics. The age of the site is dated to 16000~5000 BP cal using AMS 14C method. This finding add new materials for exploring the Paleolithic to Neolithic culture during Terminal Pleistocene-Early Holocene in Bose region. Through the comparative analysis of sites within the basin, the Dingmo site exhibits both distinctions and connections with them. Most crucially, it demonstrates certain technological differences when compared with the Zhongshan Rockshelter, which is also located within the Bubin Basin and shares chronological overlap. This implies the existence of regional technological variations within the basin. Furthermore, in comparison with contemporary sites in South China and the Yungui Plateau, Dingmo site displays both technological affinities and disparities. These observed connections and differences serve as essential reference materials for further discussions on the diversity of lithic technology across regions.This preliminary study provides new clues for investigating the evolution of Late Pleistocene lithic technology in South China and Southeast Asia.
