Description
Description Cadnant is of special interest for its geology, a complete sequence through the Cadnant Shales. The site consists of rock exposures in a railway cutting immediately outside the town walls of Conwy. A thick, Caradoc-age sequence of richly graptolitic black shales in which Elles, in a classic review of the regional geology, first recognised the ‘zone of Diplograptus multidens and Dicranograptus brevicaulis, a precursor of the present-day Diplograptus multidens Zone. A complete sequence through the Cadnant Shales is exposed with the upper part of the Coetmor Ash below and the base of the Ashgill Bodeidda Mudstones above. A key site showing a biostratigraphically important section in the Caradoc of North Wales.
