Description

Description Snape Hill Quarry is the best locality for the North Grimston Cementstone. The alternating shales and limestones represent an atypical facies in the 'normal' carbonate dominated successions of the Yorkshire Corallian. These beds contain fossil ammonites of the glosense Zone and thus are the lateral facies equivalents of the greater part of the Upper Calcareous Grit, which was deposited over most of the Corallian area. At Snape the Cementstones are overlain by a seam of the Upper Calcareous Grit, the Snape Sandstones, with Decipia are numerous belemnites. This is an important site for understanding the facies variation which existed in the late Jurassic Yorkshire Basin and its relationship to biostratigraphy. Other Information This is a new site identified as of national importance in the Geological Conservation Review.
