Functional Variation within Middle Paleolithic Ground Stone Tools

Description

In the southern Levant, ground stone tools (GST) provide insight into early plant food exploitation, butchery, and cognition. Outside of these examples, GST evidence is scarce, particularly for the Middle Paleolithic. An extensive assemblage of GST recovered from Nesher Ramla, an open-air hunting camp in Israel, presents the unique opportunity to study the role of GST within Middle Paleolithic behaviour. Use-wear and residue analysis, together with replication experiments are employed to investigate GST function within a specific period of site use by focusing on GST from the Upper Sequence (Units I-II) which reflects a trend of decreasing site-use intensity. The results indicate that GST were employed for bone breaking and knapping during the final phases of occupation while comparison with Unit V suggests longer occupations involved more diverse and extensive use of GST. GST at open-air sites are also proposed to represent a strategy for intensive exploitation of location-specific resources.
