On a Freshwater Shale with Viviparus and Associated Beds from the Base of the Carboniferous Rocks in Ribblesdale, Yorkshire

Abstract

The specimens here described were obtained by the writer from a pocket in the surface of the Silurian Slates about 200 yards to the north of Gillet Brae, exposed during the preliminary excavation for Mr. Delany's quarry (the Horton Lime Works) in 1889. The quarry is situated on the right bank of the Ribble, opposite Horton village. The site of the exposure is now buried under tip heaps and there is little chance of further sections being exposed.
