Discoid debitage stricto sensu :
a method adapted to highly mobile Middle Paleolithic groups?
Over the past ten years, descriptions of the Discoid debitage concept have become increasingly precise, resulting in the distinction of at least two methods. In addition, increasingly systematic petroarchaeological studies since the latter half of the 1980’s have contributed to our knowledge of the mobility patterns of human groups. At the same time, increasing numbers of multidisciplinary and functional studies have enabled Paleolithic researchers to better understand the role of environmental and functional factors in the technical choices made by human groups.
Discoid debitage is currently perceived as an adaptive response to mediocre raw materials. In this paper, I propose a new interpretation of the Discoid debitage stricto sensu method, not as a simple adaption of technical traditions to environmental constraints, but as a reflection of the technical traditions of human groups. The chronological longevity (from at least OIS 5 to 3) and the multiplication of assemblages attributed to this method at the end of the Middle Paleolithic could reflect a concordance between the increasing mobility of human groups and the environments that they occupied, enabling them to have more freedom in their movements.
