Multi-thematic studies on asymmetrically bifacially backed knives from the Late Middle Paleolithic. Research on equifinality and permutation on Keilmesser with tranchet blow using technological, research historical and experimental approaches.

该项目研究了石器制品，以旧石器时代中期晚期的Keilmessergruppen命名，Keilmesser（不对称双面背刀）。重点是Keilmesser与tranchet-blow修改，使用多主题的方法来分析其内在的技术特征。该项目通过对组合的重新评估、历史反思研究、考古实验和超区域比较来讨论石刻技术和时空问题。基于案例研究和超区域对比的技术数据，进行了考古实验。这些研究了矩阵和刀具配置的相关性，等量性（许多矩阵可以用来生产相同的产品）和生产阶段的排列（工作阶段的互换性），以及形状对处理的影响。实验与案例研究组合的相关性允许演绎扩展岩屑成型概念的系统性和分类，并与多视角测试概念相补充- Keilmesser与tranchet blow。从人员中提取技术特征，经过实验检验和支撑。这个研究项目的相关性在以下事实中得到证实：Bosinski和Jöris在Pradnikhorizont的配方中使用了经过检查的Keilmesser，但这些石器制品的超区域技术比较大多缺失。因此，本文的目的是基于西欧和中欧组合的区域现象，对中旧石器时代晚期的石器技术的具体方面进行超区域的反思，不仅对这些组合有考古价值，而且有助于石器系统学的证实。

This project examines stone artifacts, which are eponymous for the Keilmessergruppen of the Late Middle Paleolithic, the Keilmesser (asymetrically bifacially backed knives).The focus is on Keilmesser with tranchet-blow modification, which are analyzed using a multi-thematic approach for their immanent technological features. This project discusses litho-technological and chrono-spatial questions via the reappraisal of assemblages, a research historical reflection, archeological experiments and supra-regional comparison.Based on technological data from case studies and supra-regional correlation archeological experiments are conducted. These examine the correlation of matrix and tool confection, equifinality (numerous matrices can be used to produce the same product) and permutation of production stages (interchangeability of working stages), as well as the influence of shape on handling.The correlation of the experiments with the case-study assemblages allows to deductively expand the systematic and classification of lithic shaping concepts and to complement it with the multi-perspectively tested concept - Keilmesser with tranchet blow.Technological features are extracted in personnel, which are experimentally tested and underpinned. The relevance of this research project is substantiated in the fact that the examined Keilmesser with tranchet blow was used by Bosinski and Jöris for the formulation of the Pradnikhorizont, but supra-regional, technological comparisons of these stone artifacts are mostly missing. Therefore, the aim is, based on regional phenomena from Western and Central European assemblages, to conduct a supra-regional reflection on specific aspects of lithic technology from the Late Middle Paleolithic, which not only archeologically values the assemblages but also contributes to the substantiation of lithic systematics.
