Description and Reasons for Notification:

Stourscombe Quarry provides the best inland exposure of the Upper Devonian in South West England and the type locality of the Stourscombe Beds (Upper Famennian). Thinly bedded charts and slates here have yielded a rich fauna of trilobites and ammonoids, indicating the Wocklumeria Style Zone. This is a key site for the understanding of the Devonian succession in central Cornwall.
