The branched reduction system at the Heidenschmiede described here is hitherto exceptional for the Middle Paleolithic of the Swabian Jura. By means of refits and supporting objects, we are able to describe a superordinate reduction system that combines several individual reduction concepts, such as Levallois and blade production, within one volume. In the Middle Paleolithic of the Swabian Jura, blade technology has thus far played a rather minor role. On the one hand, it is possible to split a selected volume (nodule) into three parts, which are reduced separately according to individual concepts. On the other hand, it is also possible to reduce parts of a volume with one concept first and then with another. The hypothetical reduction system can be branched or linear, thus emphasizing the technological flexibility in core reduction, which requires a high degree of cognitive skills of three-dimensional imagination.
这里描述的海登施密德分支还原系统在斯瓦比亚侏罗纪的中石器时代是独一无二的。通过重新装配和辅助物品，我们能够描述一个上位还原系统，该系统将几个单独的还原概念（如勒瓦卢瓦技术和叶片生产）结合在一个整体中。在斯瓦比亚侏罗纪的中石器时代，叶片技术迄今一直发挥着相当次要的作用。一方面，可以将选定的体积（结核）分成三部分，根据各个概念分别进行还原。另一方面，也可以先用一个概念，再用另一个概念还原一个体积的部分。假设的还原系统可以是分支的或线性的，从而强调核心还原中的技术灵活性，这需要高度的三维想象认知技能。
