Doneraile’s Reindeer Question
Archived: 14 September 2026
Around 31,711 BCE, Ireland’s history can only be reconstructed through broad archaeological and environmental evidence. During unstable MIS 3 conditions, Derryvree in County Fermanagh preserved an ice-free, periglacial wetland with tundra vegetation. Castlepook Cave near Doneraile yielded remains of reindeer, mammoth, giant deer, hyaena and other Ice-Age animals, accumulated over extended periods. Revised dating places much fauna in MIS 3. A marked reindeer femur may record human carcass processing about 33,000 years ago, suggesting possible brief Upper Palaeolithic visits. However, no secure settlement, tools, hearths or social evidence survives. Ireland remained a changing cold landscape, not a recoverable historical society.
