The dingo has received considerable attention in the Australian archaeological literature as an agent of bone fragmentation and accumulation. Dingoes have also been studied with respect to their commensal relationship with Aboriginal people. Study has not been directed, however, to the meta-role of dingoes as prey regulators that suppress kangaroo abundance, and the subsequent impact on human subsistence that direct competition between dingoes and humans over the same animal resources could have produced This study presents data gathered in two adjacent cultural landscapes defined by human land use, one with dingoes and one without dingoes - to Illustrate the archaeological effect that dingoes may have had on human economic systems by suppressing kangaroo abundance. Live kangaroos and kangaroo skeletal remains were on average 14-fold and 32-fold more abundant in the absence of dingoes, and contemporary commercial kangaroo harvesting and sheep grazing were restricted to areas where dingoes were absent. Given the marked effects that dingoes have on contemporary kangaroo abundance and the human economy, we argue that dingoes likely shaped the human economy in the past through human-dingo competition for the same limited resources Evidence for competition between humans and dingoes could be investigated in the archaeological record by comparing the relative frequency of prey of different body sizes, as well as the degree of fragmentation of kangaroo skeletal elements, before and after the arrival of dingoes.
