Article: Conodonts from the Upper Permian strata of Nottinghamshire and North Yorkshire
Conodont elements have been found in samples of Upper Permian age from three separate areas in Nottinghamshire and North Yorkshire. The collections from Nottinghamshire comprise specimens derived from older rocks; in one area the source was of Carboniferous age, in the other it was Devonian. Collections from North Yorkshire appear to be largely indigenous and contain the zonal conodont Merrillina divergens (Bender and Stoppel) and elements of Ellisonia. These are the first identifiable Permian conodonts recorded from Britain.
