A. y- over z-axis (columns 10–15 and 17–18) and x- over z-axis (rows L-O) projection of piece-plotted Early Neolithic potsherds (N = 72), Solutrean diagnostics (N = 70; includes 29 sieve items assigned to the centroid of the square/spit field provenience), and upwardly displaced Solutrean horse tooth O13sc91. B. Refit unit REM-50 (quartzite flakes from layer K, P11-798 and P12-665). C. y- over z-axis projection of piece-plotted lithics from layers Ja-P. D. Density of quartz artefacts (total number per area unit of excavation, manuports excluded) across layers Ja-L. Elevations are in cm below datum.
