Central Hebei petroliferous area is a large oil-and gas-bearing depression located in the western part of the Bohai Gulf Basin. Tertiary strata are well developed in this area consisting of the Kongdian, hahejie, Dongying,Guantao, and Minhuazhen formation in ascending order. In the present paper,244 genera and 888 species of Ostracods, gastropods, foraminifers, dinoflogellales, acritarchs, and pollen and spores have been described.Three distinct shifts of depositional center have occurred during this period, leading to three sets of excellent oil-generating formations which contain abundant oil and gas resources
