摘要

The Eifelian Stage has been divided from bottom to top into four conodont zones: partitus, costatus, australis and kocklianus by SDS. However, the authors have rarely found the above-mentioned standard zonation conodonts in the near-shore deposits from South China though the authors have found some important Devonian organism groups such as conodonts, ammonoids, tentaculites and others in the pelagic deposits of South China. Up to now, we have only found some long-term conodonts such as Eognathodus bipennatus bipennatus, Eognathodus bipennatus montensis and Icriodus corniger corniger in the Eifelian shallow water environments from South China. Devonian near-shore deposits are widespread in South China and rich in benthic brachiopods and corals. Based on a revised taxonomy and biostratigraphic range of rugose coral assemblages in South China, a coral biostratigraphy has been established, which indicates a subdivision of Eifelian into two discrete coral assemblages.
