Threeleaf Seed Beneath Fermanagh
Archived: 28 September 2026
Around 30,531 BCE, Ireland lay within the climatically unstable Late Pleistocene, not a documented historical year. At Derryvree, County Fermanagh, freshwater silts between glacial tills preserve evidence of an ice-free interval, with tundra-like vegetation including bogbean, sedges, mosses and cold-tolerant plants. Later ice buried or disturbed much earlier evidence. Castlepook Cave, County Cork, yielded remains of mammoth, reindeer, giant deer, predators and small Arctic-adapted mammals, demonstrating an Ice Age ecosystem. A marked reindeer bone may indicate brief Upper Palaeolithic human activity, but no secure settlement evidence exists. Ireland's changing ice, habitats and uncertain connections profoundly shaped this poorly recoverable period.
