Old Stone Age

Pech de l'Azé IV - Bordes' Collection

There was a tremendous amount of inter-excavator variability in the minimum sizes of numbered artifacts (versus putting them in small find bags by square/level). Quite literally, some enthusiastic excavators had a tendency to number objects as small as 2 mm in maximum size! Such variability can grossly affect a number of measures, including artifact densities, basic counts, artifact size calculations, and artifact class ratios. For this reason, all lithic artifacts less than 2.5 cm in maximum dimension were set aside, making the remaining sample more comparable to other sites excavated with such controls.
