At the XXI UISPP World Congress in Poznan (Poland), the Functional Studies of Prehistoric Artefacts and their Socio-Economic Significance commission is organizing Thematic Session 8C 'Beyond microscopy: Advanced surface analysis and imaging Integration in functional studies of archaeological artefacts', which aims to emphasize methodological innovations and case studies that integrate multimodal surface data—geometric, chemical, and textural—to investigate functional aspects across materials such as stone, bone, ivory, antler, clay, wood, tooth, and shell, among others.
