N2 - © 2016 Elsevier Ltd and INQUAThis paper specifically examines the influence of raw material size on stone artefact assemblage formation in conjunction with two behavioural assemblage formation processes: reduction intensity and artefact transport. The aim is to establish whether raw material size can influence the way in which reduction intensity and artefact transport form a stone artefact assemblage and, should a significant influence be established, whether this has any bearing on human behavioural reconstructions. This is first investigated in an experimental setting followed by an archaeological setting using a quartzite and chert assemblage from Bone Cave in south-western Tasmania. Reduction intensity and artefact transport are respectively measured using the scar density index, flake to core ratio, non-cortical to cortical flake ratio and cortex ratio while tool blank sizes are also reconstructed. The combined experimental and archaeological analyses find that raw material size variation is capable of exerting a substantial influence on stone artefact assemblage formation. This particularly with reference to the nature of change in stone artefact assemblages: both reduction intensity and artefact transport will alter assemblage composition at faster rates when nodule sizes are smaller. This can have significant implications for intra- and inter-site reconstructions of past human behaviour.
