Awbeg’s Cave-Bone Archive
Archived: 17 September 2026
Around 33,000–34,000 calibrated years before present, Ireland lay in climatically unstable Marine Isotope Stage 3, with changing ice, coastlines and open habitats. Castlepook Cave, County Cork, preserves Ireland’s richest pre-Last Glacial Maximum vertebrate fauna, accumulated over millennia rather than representing one moment. Bones of mammoth, giant deer, reindeer, bear, wolf, hyaena, Arctic fox and lemmings demonstrate periodically viable cold-climate ecosystems. Radiocarbon dates require caution, especially for old collections. A modified reindeer bone may indicate human carcass processing about 33,000 years ago, but remains unconfirmed and cannot prove permanent settlement. No evidence establishes contemporary institutions, rituals, language, or sustained occupation there.
