The stone assemblage includes cores (n=5), flakes (n=42), chunks (n=5) and retouched tools (n=6). Lithic raw materials exploited at the locality were locally available from ancient riverbeds, with chert being the predominant raw material (72.5%). The principal flaking technique was direct hammer percussion with core preparation, especially for microblade cores. Most stone artifacts were standardized in shape, finely retouched and small in size, and most tool blanks were flakes. Only three retouched tool types were identified: scrapers, points and picks. Modified tools appear to be retouched by hammer percussion and pressure techniques, with tools retouched primarily on the dorsal surface.

Geomorphological and chronological comparison within Jixian County indicates a Late Pleistocene or Early Holocene date.
“The Taiziling locality provides important data for the study of human adaptive strategies and patterns in this region, and offers evidence for the study of lithic techniques in the Late Pleistocene/Early Holocene in North China as well as the cultural relationship between northern and northeastern China during the Pleistocene”, said first author Dr. WANG Chunxue of the IVPP.
