We analyze two technically sophisticated stone points dated between 15,580 and 14,319 cal. BP discovered at the open-air site of Mitshakila, Democratic Republic of Congo, combining diacritic analysis, experimentation, and traditional morphometrics. Diacritical analysis is applied following techno-functional (also called "morpho-structural") and productional approaches. An experimental corpus consisting of pieces produced by both a knapper from northeastern Angola in the 1950s and two lithic specialists aims at improving the identification of techniques. Finally, traditional morphometrics is used to compare Mitshakila points with several shaped points from the Late Pleistocene of sub-Saharan Africa including Tshitolian, Lupemban or Still Bay points among others.

刚果民主共和国刚果盆地压力剥落的 15 ka 旧证据

我们分析了在刚果民主共和国 Mitshakila 露天遗址发现的两个技术复杂的石尖，年代在 15,580 至 14,319 cal. BP 之间，结合了变音符号分析、实验和传统形态测量学。变音分析遵循技术功能（也称为“形态结构”）和生产方法。一个实验语料库由 1950 年代安哥拉东北部的一名 Knapper 和两名石器专家制作的作品组成，旨在改进技术的鉴定。最后，使用传统的形态计量学将 Mitshakila 点与撒哈拉以南非洲晚更新世的几个形状点进行比较，包括 Tshitolian、Lupemban 或 Still Bay 点等。
