ABSTRACT In the central plain of China, grinding tools are a common category of artefacts at sites attributed to the Peiligang Culture (c. 9000-7000 BP). This paper focuses on the grinding tool assemblage from the site of Tanghu, the largest Peiligang Culture settlement yet discovered. The results from the microwear and residue analyses both suggest that cereals were the primary plant material processed with the grinding tools. Other plants, including acorns and underground storage organs, were also processed, but probably to a smaller extent. Furthermore, microwear analysis suggests that the dry-grinding technique was adopted for cereal processing, and a piece of hide or animal skin was placed underneath the grinding slabs to gather the processed plant material. Apart from plant food processing, one of the grinding tools was also involved in processing bone. These data put more insights into the Neolithic culinary practices and different uses of grinding tools in this region.
