“…A number of open-air sites investigated on scheduled or rescue excavations have provided more precise information as to the spatial organization of settlements structured around hearths, and raise questions about the function of the sites and mobility strategies of Laborian groups. Such is the case notably of the sites of La Fosse in Villiers-Charlemagne, Mayenne (Naudinot and Jacquier, 2014), Portde-Penne in Penne d'Agenais, Lot-et-Garonne (Langlais et al, 2014b, Detrain et al, 2018, Manirac in Lectoure, Gers (Beyneix et al, 2001 ;, Champ Chalatras in Les Martres d'Artière, Puy-de-Dôme (Pasty et al, 2002) and Vaise in Lyon, Rhône (Jallet and Bouvier dir., 2012 ;Treffort dir., 2017). Within the framework of the Laborian Project (2016-2018), we have compared petrographic, techno-typological and functional data on the lithic industries, as well as data on fauna and the bone industry.…”
