Crûg  Farm Quarry

Although Crûg Quarry has been known to geologists for nearly 150 years recent research is proving that the site still has a great deal of new data to offer. Detailed study has revealed the presence of a rich and diverse assemblage of conodont microfossils which is considered unique in Britain for rocks of this age. On the basis of over thirty forms of conodont described from Crûg Farm, comparisons of this sequence have been made with strata of a similar age from various locations in Central America. Study has also been made of the other fossils recorded from Crûg Quarry and the site is now considered to be of key importance as a reference site for a number of species of trilobite.
