It is rarely possible to directly radiocarbon date skeletal remains from hot environments as collagen rapidly degrades. Although able to survive in the majority of burial environments for longer, unburnt biological apatites frequently produce inaccurate radiocarbon dates due to contamination from carbonate in the groundwater. The location of this contamination is rarely investigated, hampering development of improved methods. This paper focuses on tooth enamel and aims to test whether carbonate...[Show more]
