Abstract

The risk to surface archaeological sites posed by heavy machinery has grown significantly, and stone-tool assemblages are particularly susceptible to alteration that may be difficult to recognise. Indeed, the impact of industrial machines on surface scatters of lithic material has not yet been explored. Here, an analytical experiment is used to explore the ways in which machine action can affect a test assemblage resembling a typical Stone Age scatter. The results demonstrate that while formal tool types are not easily replicated through machine action, the creation of assemblages that resemble archaeological debitage poses a much greater challenge for archaeologists.
