Fermanagh Before Glaciation31801 BCE
Dateline
31,806 BCE is used as an archive reference year within the Late Pleistocene. No single event survives from Ireland at this exact date. Environmental evidence instead points to cold open landscapes, freshwater habitats and growing glacial influence.
Freshwater Evidence
Deposits near Maguiresbridge in County Fermanagh preserve plant and invertebrate remains from a cold treeless environment. They show that parts of Ireland remained biologically active before later ice expansion.
Wider Context
Across the British-Irish region the ice sheet was building unevenly. Later glaciation removed much earlier evidence, which explains the fragmentary archaeological record.
Primary Sources
Research draws on Derryvree studies, BRITICE-CHRONO reconstructions, Quaternary science publications, National Museum collections and radiocarbon calibration research.
