Carden’s Reindeer Incision
Archived: 25 September 2026
Abstract
Around 30,699 BCE, Ireland lay within the unstable late Pleistocene, not a datable historical year. Sediments beneath Derryvree drumlin, County Fermanagh, dated broadly to 30,500 BP, preserve evidence of open, wet tundra with arctic-alpine plants, rather than woodland or continuous ice. Castlepook Cave, County Cork, yielded diverse cold-climate animal remains, including a reindeer femur bearing a possible stone-tool cut mark. This may indicate Upper Palaeolithic carcass processing, but lacks secure excavation context and cannot prove settlement, population or route of arrival. Changing ice, sea levels and later glaciation limited access and destroyed evidence, leaving fragments rather than a continuous narrative.
