Bone tools, carnivore chewing and heavy percussion: assessing conflicting interpretations of Lower and Upper Palaeolithic bone assemblages.

Abstract

The use of bone tools by early humans has provided valuable insights into their technology, behaviour and cognitive abilities. However, identifying minimally modified or unshaped Palaeolithic osseous tools can be challenging, particularly when they are mixed with bones altered by natural taphonomic processes. This has hampered the study of key technical innovations, such as the use of bones, antlers and teeth as hammers or pressure-flakers to work (knap) stone tools. Bones chewed by carnivores can resemble osseous knapping tools and have sometimes been mistaken for them. In this paper, we review recent advances in the study of osseous knapping tools with a focus on two Palaeolithic sites in the UK, the Acheulean Horse Butchery Site at Boxgrove and the Magdalenian site of Gough's Cave, where knapping tools were mis-attributed to carnivore chewing. These osseous knapping tools are investigated using microscopy, high-resolution imaging and comparisons with experimental knapping tools. This allows for new insights into human behaviour at these sites and opens fresh avenues for future research.
