Maps of the Aurignacian sites across Europe and the Near East. (a) Each triangle indicates an archaeological site where artifacts carrying geometric signs were found. A density plot is overlaid with high (red) and low (yellow) densities of sites. (b) Zoom into the areas yielding most objects with geometric signs. Individual artifacts are plotted as black dots (with some jitter added to avoid overplotting if many artifacts come from the same site). A density plot is overlaid with high (red) and low (yellow) densities of artifacts (for script see Supplementary File 1).
