Quantitative data for the lithics from the three analyzed stratigraphic units from Shizitan 29, Layer 8, and 7 (Base and Top), and their sampling regimes: (BF) Black flint; (RF) River flint; (Q) quartz/quartzite; (O) other materials). The blade fragment found within layer 7 Base probably resulted from a limited post-depositional process repositioning it.
