1. Cretaceous Ostracoda from Eren Basin of Nei Mongol along with Sedimentary Environments
The present paper deals with the Early Cretaceous non-marine ostracods from the Saihan Tal formation of the Eren Basin in Nei Mongol Autonomous Region; all the samples under the study were collected from 40 boreholes. The ostracod fauna is dominated by species of Cypridea. With 79 species belonging to 13 genera described and illustrated, including 36 new species. Based on the composition and distribution of these species, five ostracod assemblages have been recognized in ascending order. This paper also studies and discusses the ecology and biogeography of the Cypridean fauna, the clay minerals and geochemistry of ostracode-bearing argillaceous rocks.
