The section at Longdianshan was studied in the context of the search for a new Tournaisian-Visean boundary stratotype. It was not retained as a potential stratotype but the upper Tournaisian strata yielded an excellent conodont fauna and some of these beds also provided silicified and non-silicified ostracods. The conodont fauna is characterized by the relative abundance of Dollymae and Bactrognathus species. Of these, Bactrognathus bultyncki n. sp. is described as new. The ostracod fauna consists of abundant bairdioids, locally abundant paraparchitoids, and additional elements (Bohlenatia, Tricornina, and others) of the Thuringian assemblage. The faunas recovered are illustrated and briefly commented on. The environment deduced from both conodont and ostracod assemblages is discussed as well.
