Butchery Marks at Castlepook
Archived: 8 September 2026
Abstract
Around 31,985 BCE, Ireland lay within the unstable, cold conditions of Marine Isotope Stage 3, with changing ice, sea levels and possible routes from Britain. Glaciation and later inundation destroyed much evidence. Castlepook Cave, County Cork, yielded a reindeer femur reportedly marked by stone-tool butchery, perhaps dating to about 33,000 years ago. If human-made, it indicates a brief Upper Palaeolithic visit, not permanent settlement. Cave fauna, including reindeer, mammoth and predators, reflects cold open habitats but spans different periods. No associated tools, dwellings, art or burials are securely known. Later ice erased traces; human evidence appears near the Pleistocene’s end.
