Splitting is part of this technological diversity, in the same way as grooves and splitting, these two techniques consisting in extracting elongated supports. Because it often went unnoticed, the evidence of splitting during the Magdalenian period is rare. Our study allowed us to examine its presence among the technical practices dedicated to the bone industry for this period, by questioning its methods of application and its links with the vegetal sphere. Wood is sometimes exceptionally preserved for the Magdalenian and almost absent at the Taillis des Coteaux (Vienne). The use of splitting allows us to indirectly approach the idea of a technical interaction of hard materials from the vegetal and animal worlds. We propose in this article a new look at this technical choice, by studying it in a systemic way around the different materials involved, using a technical and structural analysis of the tools, coupled with the results of the very first experimental tests that we drove. This part of the work made it possible to recognize splitting actions in the Early Magdalenian levels of the Taillis des Coteaux (17,500–16,900 BP) and to describe stigmata left on the debitage waste and the potential tools used.
