Based on changes in dimensions, production techniques such as drilling, coloration through heat treatment or the application of ochre, and stringing techniques, the OES pendant and bead use at Shizitan is divided into four phases. Phases 1–3 feature only completed ornaments, usually with heavy usewear. Only in Phase 4, during the Younger Dryas, blanks and drilled preforms are found that indicate local production. While Phase 1 features the use of larger pendants colored grey/black by burning, subsequent phases see beads replacing pendants, no heat coloration, and the use of the ochre pigment. The switch to beads corresponds with the change to microblade technology at Shizitan 29. Phase 3 shows a trend toward a larger relative surface display area and maturation of techniques to produce visual effects of roundedness and weightiness. Phase 4 local production shows technological developments that allowed drilling smaller apertures while also decreasing the bead diameter and increased standardization, implying changing display objectives (stringing beads together with a uniform appearance). The changes observed in the Shizitan diachronic dataset may relate to changing requirements in social signaling—part of the adaptations the hunter–gatherer groups made to survive the challenges of climatic change from the LGM through the Terminal Pleistocene in North China. |
