"Dark matter" of hunter‐gatherers archaeology: How many artifacts does a site lack?

The extra‐site activities of hunter‐gatherers and artifact curation between functionally different camps raise the issue of items a site lacks. This issue is usually addressed using the fractal properties of raw material. The model presented in this paper simultaneously considers the qualitative and quantitative (exponential) properties of missing artifacts. Our model was tested on Federmesser and Swiderian materials from the site of Lubrza 10, Western Poland. The obtained results confirm the utility of this model application to comparative analysis of assemblages coming from different sites and their structural units and identification of their function.
