On the Upper Pleistocene Lamellibranchiate fossil groups and paleo-oceanic environment of the Huanghai Sea

Research on Lamellibranchiate fossils of the Huanghai Sea started rather late in China and data on this subject are scarce.During the large-scale investigation of the Huanghai Sea sediment in the late 1970s, a large number of surface and core samples of the sea-floor sediment were obtained and a considerable number of Lamellibranchiatc fossils were found.A preliminary identification reveals that there are 46 species of the fossils.
The Lamellibranchiate fossils in the Huanghai Sea are composed of different species:the shallow water species, the littoral species and the fossils reflecting the environment of the estuary where freshwater flows, or of the tidal zone having brackish water.
Through the studies of the Lamellibranchiate fossils and their ecological environment, not only the features of the Lamellibranchiate groups of the Upper Pleistocene have been restored, but also some relatively important data of the investigation of paleo-current and paleo-temperature during late Pleistocene have been obtained.
