Moss-Rich Mud Below Till
Archived: 23 September 2026
Around 30,807 BCE, Ireland lay in an unstable MIS 3 Ice Age environment, not a documented historical era. Organic silts beneath till at Derryvree, County Fermanagh, dated broadly to this period, show locally ice-free tundra wetland between glacial advances, supporting mosses, sedges, freshwater life and cold-adapted plants. Castlepook Cave, County Cork, preserves remains of mammoth, reindeer, giant deer and predators, indicating episodically rich open-country fauna. A cut-marked reindeer bone may signal brief human carcass processing, but cannot establish settlement or population. Subsequent ice-sheet expansion reshaped Ireland, making these fragmentary deposits vital evidence for its pre-maximum glacial landscapes and ecological history.
