The Badegoulian technocomplex holds a special place among the West European Upper Paleolithic (UP) cultural traditions. Often understated or even bypassed by the main prehistorical overviews, caught between the fascinating Solutrean and the "classic" Magdalenian technocomplexes, it nonetheless probably marks a turning point in the evolving trajectory of hunter-gatherers in present-day France. The deep typo-technological changes, traditionally noted through lithic equipment, have recently been examined in the framework of interdisciplinary programs centered on several key-stratigraphic sequences located in southwest France. The combined analyses of flint, bone and antler assemblages, ornaments and faunal remains, together with the implementation of systematic archaeostratigraphic reassessment and radiometric dating, serve to confirm the speed and the strength of these changes ca. 23 cal ka BP. Without going into detail into the Solutrean-Badegoulian transition issue, the present paper provides a synthetic overview of the main Badegoulian characteristics-and their known variability on the basis of the lithic and osseous equipment that guided the original identification. Following a three-step structure successively exploring the "when", the "what" and the "where" questions, we will look at the current challenges in LGM chronocultural research, between (false) consensus and (true) sticking points.
