A systematic research on the late Early Carboniferous to Early Permian Brachiopods in the North China Platform shows that the evolution of the Brachiopod faunas have consistent regional characteristics. A total of 5 evolution stages and 8 assemblage zones have been identified. Five stages include the Tianshifu stage (C13～C21), the Benxi stage(C22), the Early Taiyuan stage (C23), the Late Taiyuan stage (P11) and the Shanxi stage (P12), which consist of the 1st, the 2nd, the 3rd, the 4th7th, and the 8th assemblage zones, respectively. All of these assemblage zones in the North China Platform have been compared with contemporaneous faunas in other parts of the world. Besides, the Brachiopod biogeography of the late Late Carboniferous to Early Permian in the research area has also been expounded. A new Brachiopod subprovince, the TianshanLiaoji (LiaoningJilin) Brachiopod biogeographical subprovince, has been established to represent the distribution of the Tianshifu Brachiopods in the northeastern part of the North China Platform.
