Hyaena Hall’s Last Passage
Archived: 20 September 2026
Abstract
31,087 BCE is an imprecise label for a period near the onset of Ireland’s Last Glacial Maximum. Evidence, centred on Castlepook Cave in County Cork, depicts a cold, open tundra-steppe environment inhabited intermittently by mammoth, reindeer, giant deer, wolves, Arctic foxes and spotted hyaenas. Cave bones, coprolites and feeding damage demonstrate carnivore activity within a wider Eurasian-connected fauna. A marked reindeer femur may indicate human stone-tool use around 33,000 years ago, but disturbed deposits and uncertain taphonomy prevent conclusions. No settlements or cultural evidence are securely known. Subsequent ice expansion transformed Ireland, leaving Castlepook as evidence of early human passage.
