An amorphognathoides Zone conodont fauna from the Silurian of the Ringerike area, south Norway

A limestone sample from ‘Stage’ 8-Silurian strata of Akerløkken in the Ringerike area has yielded a number of brachiopods and a diversified conodont collection. Faunal lists are presented and the taxonomy of the 49 conodont element-types identified is discussed. A new multi-element species, Apsidognathus walmsleyi sp. nov., is named and described.
