Waterford’s Pre-Ice Red Deer
Archived: 4 October 2026
Around 32,215 years ago, Ireland lay in the climatically unstable Late Pleistocene, before the Last Glacial Maximum. Evidence from bones, sediments, plants, insects and cave deposits provides ranges rather than precise annual events. Waterford caves contain pre-maximum red-deer remains, while Derryvree, County Fermanagh, preserves a cold, treeless wetland between glacial advances. Southern caves record diverse mammals, though deposits are mixed and imperfectly dated. Castlepook Cave’s marked reindeer femur may indicate brief human handling, but cannot prove settlement. Lower sea levels altered coasts without establishing a land bridge. Ireland supported life amid advancing and retreating ice, but human presence remains uncertain.
