Continuity and discontinuity at the burial site of Roonka, Murray Gorge, South Australia

Abstract

Identifying continuity and discontinuity in Holocene hunter-gatherer burial sites is often challenging. Roonka, is the largest excavated burial area in Australia. Despite preliminary analysis in the 1970–1980s chronology was challenging given the complex record of dune formation, intrusive burials, erosion and exposure. As part of collaboration with the River Murray and Mallee Aboriginal Corporation, we have re-analysed the legacy data. We have combined three tools: 3D reconstruction and spatial analysis of the site; Bayesian analysis of the radiocarbon sequence, and archaeothanatology to gain a deeper understanding of the relationships between burials and dune formation and hence the connection between changes in burial practices and environmental change. Analysis confirms that the site was used as a burial place over the last 8000 years, but the burial record has been significantly impacted by erosion. The most likely cause of erosion is ENSO-driven climatic change. Other changes that are not coincident with climatic change but alter the intensity of site use were identified by tracing the number of burials over time. Analysis indicates a shift from occasional and specialised use to increasing use in the mid to Late-Holocene. We argue that burial practices became more diverse and demographically inclusive over time. In summary, our analysis clearly demonstrates that it was not a place for everybody all the time. The selection of ‘who’ and ‘when’ demonstrates access to and maintenance of a broader set of persistent burial places in the Murray Valley region during the Holocene.
