Hyaena Hall’s Bone Traffic
Archived: 15 September 2026
Abstract
Around 31,688 BCE, a retrospective label rather than a recoverable Irish year, Ireland lay within the climatically unstable Marine Isotope Stage 3, before the Last Glacial Maximum. Castlepook Cave in County Cork preserves bones of mammoth, giant deer, reindeer, bears, wolves, Arctic foxes, lemmings and Ireland’s only known spotted hyaenas, indicating varied cold, open habitats. Disturbed excavations and revised radiocarbon dates prevent treating these remains as a single contemporaneous fauna. Hyaena evidence suggests den use. A marked reindeer femur may indicate Palaeolithic butchery, but no associated tools, settlement, or human remains exist. Environmental change, mobility and uncertainty define deep past.
