Spotted Hyaena at Castlepook
Archived: 9 September 2026
Labelled 31,941 BCE, this period represents approximately 33,900 years before present, during the climatically unstable Late Pleistocene. Ireland was not yet wholly ice-covered, but cold, seasonal tundra-steppe supported animals including reindeer, mammoth, giant deer, lemmings, wolves and rare spotted hyaenas. Castlepook Cave, County Cork, preserves disturbed remains from repeated episodes, demonstrating ecological links with north-west Europe. A reportedly cut-marked, dated reindeer femur may indicate human butchery and brief Upper Palaeolithic visits, but cannot prove settlement or continuity. No contemporary Irish camps, tools, hearths, burials, monuments or cultural evidence are securely known. Later ice expansion profoundly reshaped landscapes and obscured evidence.
