摘 要:The Middle Devonian of Wuding, Yunnan shows a continous sedimentary Series about 400m thick with the underlying Lower Devonian, and may be subdivided into three parts based on the fossils. The lower part consists of pale sandstone interbeded with black shale, yielding Wudinolepis and Arthrodira fossils. The middle part consists of yellow sandstone intercalated with marlite yielding very abundant antiarchians, Bothriolepis, Dianolepis liui and Xichonolepis etc. The upper part consists chiefly of light brown sandstone yielding Xichonolepis as well as plant fossils and is overlaid by the Jurassic rocks.
