Dwarf Willow Between Tills
Archived: 26 September 2026
Around 30,662 BCE, Ireland cannot be described through annual events or recorded communities, but through uncertain environmental evidence. At Derryvree, County Fermanagh, freshwater sediments and organic deposits between two glacial tills reveal a local ice-free interval during Marine Isotope Stage 3. Macrofossils indicate cold, wet, treeless terrain of pools, sedges, dwarf willow and sparse tundra-like vegetation. Lower sea levels altered coasts, although land connections remain unproven. Castlepook Cave’s fauna demonstrates that large mammals occupied suitable habitats, but its mixed deposits cannot date a single landscape. A possibly cut-marked reindeer bone suggests fleeting human visits, not established settlement, society or polity.
