Bogbean and the Reindeer Femur
Radiocarbon determinations of this age cannot simply be converted into calendar years. Atmospheric carbon-14 varied markedly in the Pleistocene, and modern calibration curves produce probability ranges rather than exact dates. The distinction matters. A radiocarbon age measures residual carbon-14 in once-living material; a calibrated age estimates where that measurement sits in calendar time. Neither can identify what happened in Ireland in the notional year 30,833 BCE.
