Derryvree’s Bogbean Shore
Archived: 23 September 2026
Around 30,817 BCE, Ireland’s past can only be described through broad Late Pleistocene evidence, not annual events. At Derryvree, County Fermanagh, sediments record an ice-free interval between glacial advances, with cold, open freshwater wetlands supporting sedges, mosses, aquatic plants and insects. Castlepook Cave, County Cork, preserves remains of mammoth, reindeer, giant deer and predators, although its disturbed deposits cannot reconstruct a single ecosystem. A cut-marked reindeer femur may indicate brief Upper Palaeolithic human activity, but proves neither settlement nor continuity. Environmental instability dominated, preceding the Last Glacial Maximum; no evidence exists for politics, farming, villages or institutions at this date.
