“New analysis of the skull of a brown bear discovered in Aillwee Cave in Co Clare over four decades ago has found that it is more than 10,400 years old.
The study by researchers at IT Sligo also made the surprising finding that a collection of other bones found with the bear skull include those of a second bear dated to the late Neolithic period, 4,600 years ago.
The discovery was made using radiocarbon dating during the re-analysis of more than 450 bones originally collected from the cave system in Co Clare.
The Early Mesolithic or Stone Age bones were first found when the cave was being developed as a tourist attraction in 1976.
The research was led by Dr Marion Dowd, Lecturer in Prehistoric Archaeology at the Centre of Environmental Research Innovation and Sustainability (CERIS), at IT Sligo.
