Castlepook’s Pleistocene Menagerie
Archived: 6 October 2026
Abstract
Thirty thousand two hundred and two BCE is a modern label for roughly 32,100 years before AD 1950, not a datable Irish event. Ireland then experienced cold conditions preceding expansion of the British–Irish Ice Sheet, whose extent remains uncertain. Treeless environments, meltwater and permafrost characterised exposed ground, while glaciation later destroyed sites. Castlepook Cave in County Cork preserves remains of mammoth, giant deer, reindeer, bears, wolves, Arctic foxes and hyenas, although deposits span episodes. A marked reindeer femur may indicate butchery by humans around 33,000 years ago, but no settlement evidence exists. The period reveals environmental change, not documented society.
