Cork’s Reindeer Before Maximum
Archived: 20 September 2026
Around 31,039 BCE, Ireland’s past can only be reconstructed broadly within the unstable Late Pleistocene Marine Isotope Stage 3, not assigned to a precise year. Derryvree, County Fermanagh, preserves a freshwater interval between glacial advances, dated broadly to 36,900–31,700 calibrated years BP, indicating cold, open tundra-like wetlands. Castlepook Cave, County Cork, contains reindeer, mammoth, giant deer and carnivore remains accumulated over multiple episodes, demonstrating changing ecological links with Britain and Europe. A possibly cut-marked reindeer femur suggests, but cannot prove, early human activity. No secure evidence exists for settlement, society, economy or ritual; later ice destroyed or obscured much evidence.
