Percussive-abrasive tools from Obishir-5 site, cultural horizon 2 (Fergana valley, Kyrgyzstan)

Purpose. Percussive-abrasive tools are essential for the Stone Age toolkits to process mineral and organic raw materials. This study aimed to reconstruct the functions of stone percussive-abrasive tools (n = 13) of the second cultural horizon of the Obishir-5 site (Fergana Valley), which were identified as a result of the archaeological collection analysis. Results. As a result of this study, we identified a variable set of stone instruments used by the site inhabitants for various purposes. The discovery of retouchers and hummer-stones, together with numerous debitage and cores, makes it possible to judge the presence at the Obishir-5 site of mass processing of stone raw materials to obtain blanks and their further processing into the tools. An essential result of the analysis was the identification of plates and pestle, which were most likely used for grinding organic materials. Conclusion. A new series of percussive-abrasive tools, identified as a result of the collection analysis from excavations in 2017-2021, allows us to significantly supplement the available data on the Middle Holocene lithic assemblage of the Obishir-5 site.
