Particle size distribution of lithic assemblages and taphonomy of Palaeolithic sites

► A new database on the particle size composition of experimental lithic assemblages has been built. ► Particle sorting processes due to water flow are reviewed. ► Comparison between the database and French Palaeolithic assemblages shows that many sites have been sorted upon burial. ► Sorting has a significant impact on the techno-typological balance of the assemblages.
