Identifying organic residue on ground stone tools from Mesolithic sandy sites: selected examples from Paliwodzizna 29 in Central Poland

During excavations at the Mesolithic site Paliwodzizna 29 (central Poland), in addition to the flint artefacts typical for this period and region, a collection of 175 non-flint stone artefacts was discovered. This collection included various “macro-lithic tools” displaying visible intentional modifications and usage traces. This observation prompted a preliminary traceological analysis of a selection of tools. The primary goal of the presented research was to assess the possibility of analysing and interpreting use-wear traces and potential residues on these tools. The ultimate aim was to investigate the feasibility of conducting such analyses on macro-lithic tools from the sandy sites of the Polish Lowland dating back to the Mesolithic.
