| Scope (Session Description) |
The aim of this session opens new window in interdisciplinary research for Earth science and Biology based on microfossils and fossilized micro-organisms. Microfossils, mostly unicellular eukaryotes, play key roles in multiple fields of Earth science. We welcome your presentation on evolution, ecology, biochemistry, biomonitoring, and general biological subjects of microfossils and organisms. |
