Castlepook’s Stadial Fauna
Archived: 15 September 2026
Around 31,632 BCE, Ireland lay within a severe, unstable Middle Midlandian climate, but the nominal year cannot identify a specific event. Ice margins, periglacial ground and lowered seas changed over millennia, while faunal links with Britain and Europe remained uncertain. Derryvree in Fermanagh preserves evidence of treeless, waterlogged tundra vegetation and freshwater habitats. Castlepook Cave in Cork contains a time-mixed Late Pleistocene bone archive, including mammoth, giant deer, reindeer, bear, hyaena, wolves and lemmings. These remains indicate open cold-country ecosystems, not a simultaneous community. Direct evidence for human occupation is absent or disputed. Glacial processes shaped landscapes inherited by Ireland.
