In Dongpu region, including northern Henan province and western Shangdong
province, the Early Tertiary sediments with rich fossils are well-developed
as those in the coastal region of Bohai and can be divided in ascending
order into three units, the names of which are the same of the coastal
region of Bohai as follows: the Kongdian Formation, the Shaheji Formation
and the Dongying Formation. In this region the Early Tertiary nonmarine
ostracode fauna contains 23 genera and 94 species, including 16 new species.
This ostracode fauna is similar to that from the coastal region of Bohai.
In the former fauna there are, together with usual freshwater genera,
a large number of endemic forms previously appearing in the Early Tertiary
deposits of the coastal region of Bohai, but the former one is less abundant
than the latter. In this ostracode fauna seven ostracode assemblages,
closely corresponding to those from the coastal region of Bohai, have
been recognized in ascending order as in Table 1: After analysing the
characters of these two ostracode faunas mentioned above, it is suggested
that they belong to the same biogeographic realm and possess the similar
ecological conditions.
