Carden Reindeer Femur
Archived: 7 October 2026
Around 30,152 BCE, Ireland lay within the climatically unstable Late Pleistocene, before the Last Glacial Maximum. Evidence cannot identify events in a single year, but Derryvree sediments in Fermanagh reveal locally exposed, treeless periglacial habitats with freshwater and tundra vegetation. Castlepook Cave, County Cork, preserves a mixed, long-lived faunal record including mammoth, giant deer, reindeer, bears and hyenas, demonstrating intermittent access for animals. A reindeer femur bearing a possible stone-tool cut may indicate brief human carcass processing about 31,000 BC. However, no associated settlement, tools, hearths or human remains prove occupation. Ireland’s history is environmental: shifting habitats, coasts and routes.
