A Moss Bed at Maguiresbridge
Archived: 29 September 2026
Around 30,507 BCE, Ireland has no recoverable record of human events; the date denotes a broad later Pleistocene interval. At Derryvree near Maguiresbridge, Fermanagh, organic silts between glacial tills preserve evidence of an ice-free or locally ice-free periglacial wetland. Plants, mosses, pollen and insects indicate treeless tundra, freshwater pools and severe seasonal conditions. Later ice sheets altered Ireland. Castlepook Cave, Cork, contains diverse cold-stage animal remains, including mammoth, reindeer and hyaena, but its deposits span long periods. A possibly cut-marked reindeer bone suggests early human presence, yet proves neither settlement nor continuity. Environmental evidence remains stronger than evidence for people.
