Castlepook Femur Under Scrutiny
Archived: 20 September 2026
31,072 BCE is a modern chronological label, not a precisely narratable Irish year. During Marine Isotope Stage 3, Ireland experienced cold, unstable conditions as the British-Irish Ice Sheet expanded, though some terrain remained ice-free. Derryvree, County Fermanagh, preserves a freshwater wetland sequence indicating treeless periglacial habitats, pools and varied plant life. Castlepook Cave, County Cork, contains mixed late Pleistocene animal remains, demonstrating repeated faunal presence rather than a single community. A marked reindeer femur may indicate very early human activity, but requires scrutiny. No settlement or culture is established. Later glaciation erased evidence, leaving fragmentary environmental and archaeological records today.
