Cork’s Hyena-Den Landscape

Archived: 6 October 2026

Abstract

Around 30,190 BCE, Ireland lay in the later Marine Isotope Stage 3, approaching major glaciation but not necessarily uniformly ice-covered. Dating and ice margins remain uncertain. Glacial processes were shaping landforms later visible across Ireland. Castlepook Cave, County Cork, preserves a time-averaged MIS 3 fauna including reindeer, mammoth, giant deer, bears, wolves and spotted hyenas. Revised dates mean these animals cannot securely be placed in this year. Treeless or sparse cold-steppe and tundra supported shifting ecological communities, while changing sea levels and ice affected dispersal. No accepted evidence demonstrates human settlement or activity; Ireland’s earliest confirmed human evidence is later.

Cave Hyenas at Castlepook

Abstract

Thirty-one thousand years BCE is an imprecise modern label for a Late Pleistocene interval, not a documented Irish year. During Marine Isotope Stage 3, Ireland experienced cold, treeless, changing conditions, with ice margins and sea levels fluctuating. Derryvree, County Fermanagh, preserves wetland deposits indicating ice-free ground before later glacial advance. Castlepook Cave, County Cork, contains diverse fauna, including reindeer, mammoth, giant deer, bear, Arctic fox, lemmings and cave hyena, demonstrating intermittent ecological connections with Eurasia. Possible butchery marks suggest human presence, but remain unconfirmed. No settlements are known. Later ice expansion transformed habitats and destroyed or buried much physical evidence.
