Abstract

Despite its strategic location within the continent, Central Africa is rarely integrated into the reconstruction of population dynamics during the Middle Stone Age (MSA) of Africa, especially in terms of the emergence, diffusion and behavioural patterns of Homo sapiens. However, hundreds of sites have been discovered in Central Africa during the 20th century and attributed to the Lupemban, one of the main MSA technological complexes of the region. This complex is mainly characterised by typological criteria based on the numerous bifacial pieces found in the Congo Basin and interpreted as an adaption to the rainforest environment. Most of these Lupemban assemblages have not been studied for decades and thus it is particularly difficult to assess their diversity. This paper presents a detailed combined morphometrical approach (linear measurements and indices, Log Shape Ratio, Elliptic Fourier Analysis) to take a fresh and rigorous look at the Lupemban bifacial tools. We discuss the comparison of different morphometrical approaches to deal with “old” collections for which contexts, particularly chronological ones, are partially missing. We present the results of this approach on three assemblages of bifacial pieces gathered in the 1930s and late 1960s. We quantify their variability and discuss not only their homogeneity but also the variation of a Lupemban hallmark, namely the “Lupemban point”.
用形态计量学重新评价旧藏品:以刚果盆地中石器时代双面工业为例
尽管中非处于非洲大陆的战略位置,但中非很少被纳入非洲中石器时代(MSA)人口动态的重建,特别是在智人的出现、扩散和行为模式方面。然而,在20世纪,在中非发现了数百个遗址,并归因于该地区主要的MSA技术综合体之一Lupemban。这个建筑群的主要特征是基于在刚果盆地发现的许多双面碎片的类型标准,并被解释为对雨林环境的适应。这些Lupemban组合中的大多数几十年来都没有被研究过,因此评估它们的多样性特别困难。本文提出了一种详细的组合形态计量方法(线性测量和指数,对数形状比,椭圆傅立叶分析),以一种新鲜而严谨的方式看待Lupemban双面工具。我们讨论了不同形态计量学方法的比较,以处理上下文,特别是时间顺序的,部分缺失的“旧”集合。我们介绍了这种方法在20世纪30年代和60年代末收集的三组双面碎片上的结果。我们量化了它们的可变性,不仅讨论了它们的同质性,而且还讨论了一个Lupemban标志的变化,即“Lupemban点”。
