Fusulinid and foraminifera in Carboniferous-Permian Taiyuan formation in Yanzhou Coalfield, Shandong, Northeast China

The Carboniferous–Permian boundary is still in high debate in China though this boundary was settled in Aidaralash Creek in Kazakhstan in 1995, where the Global Stratotype Section and Point (GSSP) were defined. The topmost Carboniferous lies in the bottom of fuslinida Pseudoschwagerina in the world, but in the upper part of fuslinida Pseudoschwagerina in China. Taking Yanzhou Coalfield as an example, we explore here the boundary between Carboniferous and Permian on the basis of biological evolution and biostratigraphy. This work could be helpful to understand the special situation of the boundary between
