| Abstract: | A latest Permian (late Changhsingian) radiolarian fauna is recorded from the upper Talung Formation, Hushan, Nanjing, Jiangsu Province, South China. This fauna includes 24 species belonging to 16 genera; new species are Albaillella hushanensis, Copicyntroides stellatus and Trilonche crassus. The presence of the radiolarian fauna and its taxonomic composition reveal that the Eastern Qinling-Dabie deep sea, which was located along the northern margin of the northeastern Yangtze Basin, persisted at least until the end of the Palaeozoic and that the collision between the North China and South China plates had not occurred by the end of the Permian. |
