Late Pleistocene Megafauna and Archaeology from Cuddie Springs, South-eastern Australia

Abstract

The Cuddie Springs site in south-eastern Australia provides the first evidence of an unequivocal association of megafauna with humans for this continent. Cuddie Springs has been known as a fossil megafauna locality for over a century, but its archaeological record has only recently been identified. Cuddie Springs is an open site, with the fossil deposits preserved in a claypan on the floor of an ancient ephemeral lake. Investigations revealed a stratified deposit of human occupation and fossil megafauna, suggesting a temporal overlap and an active association of megafauna with people in the lead up to the Last Glacial Maximum, when conditions were more arid than the present day. Two distinct occupation phases have been identified and are correlated to the hydrology of the Cuddie Springs lake. When people first arrived at Cuddie Springs, sometime before 30,000 BP, the claypan on the lake floor was similar to a waterhole, with five species of megafauna identified. Flaked stone artefacts were found scattered through this level. After the lake dried, there was human occupation of the claypan. The resource base broadened to include a range of plant foods. Megafauna appear to be just one of a range of food resources exploited during this period. A return to ephemeral conditions resulted in only periodic occupation of the site with megafauna disappearing from the record around 28,000 BP. The timing of overlap and association of megafauna with human occupation is coincident with the earliest occupation sites in this region. The archaeological evidence from Cuddie Springs suggests an opportunistic exploitation of resources and no specialised strategies for hunting megafauna. Disappearance of megafauna is likely to be a consequence of climatic change during the lead up to the Last Glacial Maximum and human activities may have compounded an extinction process well under way.
