6,000-year-old settlement poses tsunami mystery
Radiocarbon dating of a shellfish midden on Fanore Beach in north Clare have revealed it to be at least 6,000 years old — hundreds of years older than the nearby Poulnabrone dolmen.
The midden — a cooking area where nomad hunter-gatherers boiled or roasted shellfish — contained Stone Age implements, including two axes and a number of smaller stone tools.
