abstract = {{The origin of tool use is a central question in human evolutionary studies. {\textless}br{\textgreater}Plio-Pleistocene core and flake technologies represent the earliest evidence {\textless}br{\textgreater}of tool use in the human lineage. Some suggest this form of tool use is {\textless}br{\textgreater}probably pre-dated by a phase of percussive tool use. However, there is {\textless}br{\textgreater}currently no evidence for such a record. The archaeological signature of {\textless}br{\textgreater}solely percussive behaviours is not as well understood as that associated {\textless}br{\textgreater}with cores and flakes. The durable nature of primate percussive stone {\textless}br{\textgreater}tools and their by-products provide an opportunity to investigate what {\textless}br{\textgreater}such a record looks like. Here, we present a landscape-scale study of the {\textless}br{\textgreater}chimpanzee (Pan troglodytes verus) material culture from the Djouroutou {\textless}br{\textgreater}Chimpanzee Project, Ta{\"\i} Forest, Cote d{\textquoteright}Ivoire. This study explores the {\textless}br{\textgreater}interplay between behavioural and environmental factors in shaping the {\textless}br{\textgreater}stone record of nut cracking. Through a survey of nut-cracking sites, the {\textless}br{\textgreater}available nut species, and raw materials, we show how resource availability {\textless}br{\textgreater}influences the resulting material signature of nut cracking. These results {\textless}br{\textgreater}also reveal the diversity of material signatures associated with a purely {\textless}br{\textgreater}percussive material record. We gain insight into the range of signatures {\textless}br{\textgreater}that may be associated with a pre-core and flake archaeological record, {\textless}br{\textgreater}providing new expectations for an earlier record of tool use.}},
