摘要:石镞主要是旧石器时代晚期出现的一种投射类复合武器的尖端,其使用方式一直为学术界所关注。本文以山西吉县柿子滩遗址环境背景和石器原料为参照,通过微痕实验,探讨射击类带尖石制品重复使用过程中微痕的动态形成过程。作者对21件实验标本分阶段累计射击337次,微痕观察121次。分析结果显示,射击类带尖石制品的重复使用情况可以通过微痕进行佐证。形态变化过程表明,尖端变化较为显著,指示应以动态思维考量出土石镞形态及其暗示的人类行为;测量数据显示,尖端及侧刃较为锋利、长度适中的标本,射击效果更好,存在多次使用的可能;微痕分析指示,若尖端产生层叠大中型折断式、阶梯式疤痕,装柄部位产生连续小型折断式或羽翼式疤痕,部分出现磨圆与光泽时可以考虑重复使用的可能。本项研究为揭示石镞背后所蕴含的狩猎策略、生计方式等人类行为信息提供了数据参考。

Abstract: Projectile point, appeared in the Upper Paleolithic, includes tips and barbs of a projectile composite weapon. It’s using strategies have gotten great attention in the paleoanthropological research. Based on the environmental background and lithic raw materials of the Shizatan Paleolithic site in Shanxi, this paper focus on the use-wear analysis to explore the dynamic formation process of microwear during the process of reuse of stone projectile points. Twenty-one experimental tools were shot for 337 times in different stages, while 121 times observed by use-wear analysis. It can be considered that the repeated use of stone projectile points can be recorded by microwear, but it still needed to combine with morphological characteristics. Viewing on the morphological change process, the change of tip is more significant, indicating that the shape of excavated artefacts and its implied human behavior should be considered by dynamic thinking. From the view point of measurement data, tools with sharp edge and moderate length have better affected of using and may be reused many times. Furthermore, from the view point of microwear analysis, if the tip produces clumped large and medium break and/or step scar termination and hafting part produces run-together small break or feather scar termination, resulting in some of part produce rounding and polishing which can be considered for re-use. This study provides important clue for the study on the hunting strategies and adapted behaviors implicated from the projectile point in the hunter-gathered living history.
