This technology, associated with the most recent Neandertal known, is analyzed here in its spatio-temporal context. Observations pertaining to technological differentiation and to the organization of space in the rockshelter are presented, and the significance of these new data to the transition from Middle to Upper Paleolithic is briefly discussed. lun., 11 mai 2026 16:30:52 +0200 lun., 11 mai 2026 16:31:02 +0200 https://popups.uliege.be/3041-5535/index.php?id=177 https://popups.uliege.be/3041-5535/index.php?id=150 A blade core of Maastrichtian Hesbaye flint from the Gravettian site of Huccorgne, Southeast Belgium, was refitted to twenty-nine blade fragments, flakes, and pieces of debris. Technological analysis of the lithic operatory chain involved in the reduction of this core, as well as material analysis of internal fissures, suggest that the core was reduced during at least two episodes in spatially discrete portions of the archaeological site. The temporal period between reductions is unknown, but it is posited that the internal crack propagation was the product of exposure to severe cold at the beginning of the Last Glacial Maximum. lun., 11 mai 2026 16:09:43 +0200 lun., 11 mai 2026 16:14:42 +0200 https://popups.uliege.be/3041-5535/index.php?id=150
