Summary from English Wikipedia (enwiki)

Sometimes referred to in literature as 'Bwlch y Gaseg' and in very close proximity to the area named as such on OS Map (six-inch to the mile) 1888-1913, the Cynwyd Forest Quarry is a Site of Special Scientific Interest (SSSI) located aside a track within the Cynwyd Forest near Corwen , Denbighshire, North Wales. It was described by Rushton et al. (2000) and exposes Late Ordovician micaceous siltstones and mudstones of the Dolhir Formation (Ashgill Series, Rawtheyan Stage) which yields a rich shelly (brachiopod) fauna. Trilobites are represented by several genera although the fauna is dominated by Gravicalymene arcuata Price, 1982. Bivalves, bryozoans and various Echinodermata (Crinoids and Cystoids) are also present. Examples of most of the fossils listed below are illustrated and briefly described (or remarked upon) in "Fossils of the Upper Ordovician" by Harper and Owen (Eds.).
