Aquatic and terrestrial Phanerozoic microfossils with organic walls are among the most important primary producers, and through their activity, they have had a profound impact on the hydrosphere, atmosphere, and lithosphere. Changes in their diversity throughout geological time also allow for the identification of significant crisis periods and their accurate interpretation within the relative timescale. In this way, the rate, manner, and effects of past climate fluctuations, among other factors, can be assessed, providing a foundation for the development of future scenarios.

Funding from basic financing can be used for further unraveling the phylogenetic relationships between dinoflagellate cysts (Mesozoic and Cenozoic) and acritarchs (Paleozoic) through spectroscopic techniques (FTIR), the reconstruction of Holocene settlement history in coastal areas through palynological analysis using pollen and spores, and the relative dating of Paleozoic sediments through biostratigraphic analysis using acritarchs and chitinozoans.
