Declining foraging efficiency and moa carcass exploitation in southern New Zealand

The application of foraging theory to understanding carcass exploitation is a relatively recent development. The methodology developed by archaeological and ethnoarchaeological research on butchery/transport studies has been integrated into a behavioral ecological framework to create models that can be used to understand archaeological carcass exploitation. In this paper, I use such a model to examine how New Zealand foragers altered their use of moa carcasses as the availability of these large birds declined. Moa data from the Shag River Mouth site in southern New Zealand are analyzed to test changes in butchery/transport and skeletal element breakage patterns expected with resource depression and declining foraging efficiency. This research shows that at Shag Mouth, field processing of moas increased and marrow, and possibly grease extraction intensified over time.
