Abstract
Around 31,932 BCE, Ireland lay in a cold, unstable pre-Last Glacial Maximum environment as the British–Irish Ice Sheet expanded. Precise annual dating is impossible; evidence derives from radiocarbon-dated cave fauna and reconstructions. Castlepook Cave, County Cork, preserved remains including mammoth, reindeer, giant deer, bear, wolf, Arctic fox, lemmings and hyaena, indicating intermittently habitable open terrain. A reindeer bone may bear stone-tool marks and date to about 33,000 years ago, suggesting a possible human visit. However, disturbed old collections and uncertain context prevent proof of occupation. Later glaciation erased much evidence, while modern re-dating and excavation continue refining Ireland's Palaeolithic record.

Abstract
Around 32,000 BCE, Ireland lay within the Late Pleistocene, before the British–Irish Ice Sheet reached its maximum extent. Lower sea levels altered coasts, but any land connection to Britain or Europe remains uncertain. Conditions varied regionally, though open, cold steppe-tundra supported reindeer, mammoth, giant deer, bears, wolves, Arctic foxes and fauna. Castlepook Cave, County Cork, preserves animal remains and a reindeer bone possibly bearing stone-tool butchery marks. This tentative evidence may indicate human activity, not settlement. Later glaciation destroyed or buried landscapes, complicating interpretation. Evidence of people in Ireland dates to about 10,860–10,640 BCE, leaving this earlier period archaeologically uncertain.
