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.

Abstract
About 31,746 BCE, Ireland formed part of a climatically unstable MIS 3 Ice-Age landscape, with low sea levels, shifting ice margins and changing land connections. Castlepook Cave in County Cork preserves important, imperfect evidence: animal remains indicate open tundra-grassland habitats supporting mammoth, giant deer, reindeer, hyaena, wolves and Arctic species. These bones accumulated through natural processes as well as predators, while early excavation and revised dating limit certainty. A reindeer femur possibly bears a stone-tool cut mark, suggesting an exceptionally early human visit or carcass processing. It cannot prove settlement or continuity. Ireland’s evidence chiefly records fauna and environmental uncertainty.

Abstract
31,903 BCE is not a securely identifiable Irish year but falls within climatically unstable Marine Isotope Stage 3. Ireland’s changing ice, exposed shelves and open, cold habitats intermittently supported mammals, although later glaciation erased much evidence. Castlepook Cave, County Cork, preserves Ireland’s richest relevant faunal archive, including mammoth, reindeer, giant deer and spotted hyaena, but its disturbed, long accumulated deposits cannot prove contemporaneity or date species precisely to this year. A possibly cut-marked reindeer bone suggests an unconfirmed early human encounter. No settlements, societies or economies are evidenced. The period is understood through fragmented animal remains, cave processes, climatic change.
