The Paleogene lacustrine microfossils of Bohai Gulf Basin are characterized by their high abundances, high diversities, high proportion of local species as well as saline species and the occurrence of talassogenous fauna.

The abundances and ratios of microfossils as well as carbonate contents in the surface sediment samples from the northeastern part of the South China Sea were quantitatively analyzed in this study.

On the basis of the experience and test comparison working for many years,the authors summarize the optimal coating method and coating film thickness for the non electric conductive microfossils,such as Radiolaria,diatoms, tentaculites ,foraminifera,Ostracoda,Charophyta,conodont and sponge spicule.

The importance and the extraction history of microfossils are briefly introduced.

Preliminary study on cladoceran microfossils in the sediments of Lake Taihu;

The microfossils described and illustrated in this paper were discovered in the black chert of the lower Cambrian Shuijingtuo Formation at Baiguoping, Hefeng, Hubei Province.

Phosphatized microfossils,something like Weng\'an biota,were reported by Zhou et al.

New data of nannofossils in the Shadui Formation in the Yamzho Yumco area, Tibet;

Calcareous nannofossils analysis has been carried out for 308 surface sediment samples taken from the west of the South China Sea within a wide range of water depth from 36 to 4 245 m.

Based on the study of nannofossils in ferromanganese crusts MDD-53-1 and MED-48-1 collected from Magellan Seamounts in the western Pacific,the nannofossil species H.

The results show that the total abundance of calcareous nannofossils is different among the samples.
