Waterford’s Ancient Red Deer
Archived: 5 October 2026
Approximately 30,246 BCE, Ireland experienced unstable Late Pleistocene conditions, with fluctuating ice margins, low sea levels and altered connections to Britain. Derryvree, County Fermanagh, preserves a wetland sequence between glacial advances, indicating cold, treeless freshwater vegetation, but not conditions across all Ireland. Waterford cave finds date red deer to a relevant pre-Last Glacial Maximum interval, demonstrating occasional large herbivore presence in the south-east. Castlepook Cave records diverse cold-stage fauna, although deposits are time-averaged. Possible tool marks on a reindeer bone suggest human visits, not settlement. No evidence supports communities, farming, politics or culture. Fragmentary records reveal a dynamic Ice-Age landscape.
