Doneraile’s Marked Femur
Archived: 20 September 2026
Abstract
31,064 BCE is a modern label for a late Upper Palaeolithic interval, not a documented Irish year. During Marine Isotope Stage 3, Ireland experienced cold, fluctuating conditions as the British–Irish Ice Sheet expanded towards its later maximum. Derryvree, County Fermanagh, preserves a freshwater tundra wetland with cold-adapted plants, insects and sediments between tills. Castlepook Cave, County Cork, yielded mammoth, reindeer and hyaena remains, including a reindeer femur possibly cut with a stone tool. This may indicate brief human carcass processing, but cannot prove settlement. No secure tools, hearths, structures, burials or evidence of society, culture, routes or permanent occupation survives.
