Description

Area,7.8 hectares 19.3 ac Description Keisley Quarry lies three kilometres north east of Appleby on the Pennine foothills between the villages of Murton and Dufton. This disused limestone quarry represents the type locality of the richly fossiliferous Keisley Limestone of Upper Ashgill age. The rocks contain abundant brachiopods and trilobites and have yielded much type material. Some authors consider the limestone to containa fauna representative of the high Ashgill “Hirnantia community”. Of particular significance is the rich conodont fauna of the limestone, unique in its diversity at this horizon in great Britain.
