Reindeer Question
Archived: 9 September 2026
Circa 31,876 BCE, Ireland was a cold, unstable Late Pleistocene landscape, not a historically documented country. Ice-free freshwater environments in Fermanagh, evidenced at Derryvree and Greenagho, show that later glaciation had not yet covered all regions. Castlepook Cave in Cork preserves remains of mammoth, giant deer, reindeer and other cold-adapted fauna, although deposits represent multiple episodes. A cut-marked reindeer femur may indicate brief human butchery or handling, but cannot prove settlement or continuity. Lower sea levels altered coasts without establishing certain migration routes. Expanding ice later transformed and obscured the landscape, leaving sediments and cave bones as the principal archive.
