摘要
The ostracods of Late Cretaceous Wujia Formation and Palaeocene Shangyang Formation are found from 18 samples of 8 boreholes in the Hepu Basin, Guangxi. Twenty three species in 14 genera are figured, including one new species. The ostracod fauna is subdivided into two assemblages: 1) Rhombicypridea quadrata-Heterocypris hepuensis-Limnocythere sinuata assemblage from the Wujia Formation, belonging to Talicypridea fauna of the Late Cretaceous; and 2) Sinocypris excelsa-Cypris concina-Parailyocypris changzhouensis assemblage from the Shangyang Formation, belonging to Sinocypris fauna of the Palaeocene.
