LATE CRETACEOUS OSTRACODS FROM THE NANXIONG GROUP IN THE NANXIONG BASIN OF GUANGDONG PROVINCE

The taxonomy and biostratigraphy of the Talicypridea-Cypridea-Nanxiongium ostracod fauna from the Nanxiong Group in the Nanxiong Basin is of great importance for the subdivision and correlation of the Upper Cretaceous non-marine strata in China. Abundant ostracods have been recovered in 270 samples from the Zhutian and Zhenshui formations, the upper part of the Nanxiong Group. There are 99 species in 23 genera (including 2 subge- nera) figured herein, including 12 new species herein described. This ostracod fauna is dominated by species of the four genera: Talicypridea, Cypridea, Nanxiongium, Candoniella. This ostracod fauna has also been reported from the Upper Cretaceous strata in Mongolia.
