The preservation of the basic morphological features of some filamentous Oscillatoriales (genus Phormidium) during four modes of artificial fossilization for mummification and formation of organic-walled microfossils was investigated. Posthumous variations of morphology of Oscillatoriales under various modes of fossilization - silification, phosphatization, carbonization, and formation of organic-walled microfossils (mummification) - are compared. The possibility of homologization of some morphological features of living Cyanophyta and microfossils with different modes of fossilization is demonstrated. Representation of main ecological groups of microorganisms and algae in fossil record is discussed.
