As primary producers,acritarchs that represented the base of the food chain in the Early Paleozoic marine ecosystem formed the marine phytoplankton communities whose distributions might affect those of other faunas.Ten acritarch ecological assemblages with their distributions controlled by the environmental factors were recognized in the Meitan Formation of the Honghuayuan section,Tongzi,Guizhou Province,the Dawan Formation of the Huanghuachang and Daping section,Yichang,Hubei Province,and the Dacao Formati...
