Hyaenahall’s Mammoth Horizon
Archived: 8 October 2026
Abstract
About 30,121 BCE, Ireland lay in a cold, unstable Late Ice Age landscape as the British–Irish Ice Sheet expanded. Open tundra-like habitats, altered coastlines and routes supported cold-adapted fauna, while glaciation later destroyed or buried much evidence. Castlepook Cave in County Cork preserves Ireland’s vertebrate archive for this period, though its mixed deposits span many millennia and were excavated. Bones of mammoth, reindeer, giant deer, hyaena, wolves and Arctic mammals demonstrate animal access. A possibly tool-marked reindeer bone may indicate human activity around 33,000 years ago, but cannot establish settlement, society or sustained occupation. The period remains an environmental history.
