Kiltorcan Quarry Fossils.
The Quarry at Kiltorcan is 400 million years old and is internationally known for its rich assemblage of fossil ferns since 1853. As well as the large and spectacular plant fossils, the site has yielded freshwater bivalve, crustacean and fish fossils (freshwater mussel shells, fish scales and some rare arthropods) – providing a well preserved snapshot of life at the end of the Devonian period (400 million years ago) when significant evolution amongst plants was taking place. There are pieces on display in The National History Museum in Dublin and the Rothe House Museum in Kilkenny.
