China Seas have very expansive areas with complete geographic and topographic units containing diverse ecologic and depositional environments, which are the good natural places for micropaleontologic research. Works on marine micropaleontology in China started in the late 1950’s, and in the last thirty years, the marine micropaleontology in China has been greatly expanded into a full-fledged discipline that includes taxonomy, ecology, sedimentology, biostratigraphy, paleoenvironmental analysis and geologic resources prospecting, and deals with finding and explaining various species buildup, ecologic condition, sedimentary distribution, and their historical processes. All of these have provided much-needed basic information and produced many research papers on marine micropalaeoceanography in various high-profile journals around the world. This review summaries some aspects in the course of micropaleontologic development in China.
