This thesis interprets the task association and functions of stone artefacts from Christmas Creek Rockshelter, south east Queensland, through use-wear and residue analysis. This is the first such study to be carried out on artefacts from the site. Aboriginal habitation in the Region has largely been explored through technological analyses of stone tools (Hall and Hiscock 1988a). Technology change through time, exhibited at sites in the Region had been linked to changes in resource exploitation, site usage and/or artefact function (Hall and Hiscock 1988a, Novello 1989). However, use-wear and residue analysis performed on artefacts from Platypus Rockshelter suggested that this was not the case (Skelton 1996:98- 99). Thus, the results of this research provide an important comparison to the Platypus Rockshelter analysis. This study also adds to knowledge about Aboriginal settlement and change in The Moreton Region during the late Holocene.
The use-wear and residue analysis of 89 artefacts from the site revealed task associations of general and starchy plant processing, wood-working and secondary skin-processing. Plant processing activities dominated the assemblage and remained stable through time, suggesting that resource exploitation, tool function and site usage was not linked to technological change noted at the site. These results and conclusions supported the findings from Platypus Rockshelter. However, the task of secondary skin processing was found to be absent during the time technological change was occurring. This was an interesting correlation, although a larger sample would need to be identified and analysed before any definitive conclusions could be drawn.
