The Doneraile Bone Archive
Archived: 27 September 2026
Thirty thousand five hundred and seventy-eight BCE is a modern approximation for a Late Pleistocene Irish landscape in Marine Isotope Stage 3, near Greenland Interstadial 5.2. Ireland experienced comparatively milder yet volatile glacial conditions, with lower seas and changing access routes. Castlepook Cave near Doneraile, Cork, preserves over 2,000 bones accumulated across millennia, including mammoth, reindeer, giant deer, bear and hyaena. These indicate open, cold habitats, but do not form a single contemporary scene. A possibly stone-tool-marked reindeer bone raises early human presence, though no securely associated settlement evidence exists. Later ice expansion erased or buried evidence, requiring cautious interpretation.
