| Abstract: | Middle Devonian brachiopods are widely distributed in Guangxi Province of South China.167 species in 69 genera belonging to 45 families have been recorded in 20 investigated Middle Devonian sections.Biostratigraphically,73 species in 47 genera occur in the Eifelian Stage,and 100 species in 32 genera in the Givetian Stage.Cluster analyses based on the generic data from each locality within these stages indicate that brachiopod diversities and abundance also vary in different depositional environments.The fau... |
