Scope 
The aim of this session opens new window in interdisciplinary research for Earth Sciences and Biology based on microfossils and protists. Microfossils have been widely used in multiple fields of Earth Sciences because of their precise and continuous fossil records over the Phanerozoic eon and their wide distribution/high production on the Earth. Such fossilized micro-organisms are also used as excellent indicators to monitor drastic environmental changes and pollution in the present time. In the last 20 years, molecular biological approaches on protists have improved our knowledges of their evolution and diversity, and the research subjects are expanding to ecology, cell biology, and metabolisms. The integration of earth scientific and biological knowledges and techniques will provide innovation in protists/microfossil sciences. For this purpose, we welcome presentations from various fields: evolution, ecology, biogeochemistry, biomonitoring, etc. of microfossils and protists.
