Cork’s Lost Hyena Range
Archived: 19 September 2026
Around 31,136 BCE, Ireland formed part of an unstable Late Pleistocene landscape, rather than a setting with recoverable annual history. Derryvree, County Fermanagh, preserves a buried, ice-free freshwater wetland dated broadly to MIS 3, supporting treeless tundra vegetation. Castlepook Cave, County Cork, produced fossils of reindeer, mammoth, giant deer, predators and Ireland’s only known spotted hyaena remains, demonstrating intermittent access by cold-stage fauna. A marked reindeer bone may indicate human butchery, but cannot prove settlement or cultural affiliation. Expanding ice later transformed and obscured landscapes. Evidence reveals changing environments and animals, not named people, institutions, trade or events with certainty.
