The Awbeg Cutmark Debate

31,648 BCE is a modern label for a fluctuating MIS 3 Ice Age environment, not a recoverable Irish historical year. Derryvree, County Fermanagh, preserves freshwater sediments between glacial tills, indicating locally ice-free, treeless wetlands and open periglacial vegetation during a broadly dated interval. Castlepook Cave, County Cork, contains a complex, repeatedly accumulated fauna including mammoth, reindeer, giant deer, bear and hyaena, but cannot represent a single contemporaneous community. A marked reindeer femur may indicate brief human butchery, yet remains inconclusive. No settlement, culture or economy is demonstrable. Changing ice, wetlands, animal movements and fragmentary evidence define this period in Ireland.
