III.—The Fauna of the Hydraulic Limestones in South Notts

Abstract

Although numerous papers, principally by the late E. Wilson, describing the beds of the Rhætic and the Lower Lias of Notts, were published while exposures existed along railway cuttings in the south-east of the county, no account of the precise positions of important fossils is to be found. These exposures are now all grass-grown, but the junction of Rhætic and Lias may be seen in a number of quarries where hydraulic limestone is worked, either for cement or for road material. One of the best is at Owthorpe. Those at Cotgrave Gorse, Barnstone, Plumtree Wolds, and Normanton Hills are confirmatory. The layers rich in Foraminifera have been of value in correlating these sections.
