The Yakut scientists are researching the Precambrian mushroom
Scientists of Yakutia are exploring the Precambrian mushrooms found in sedimentary rocks on the republic territory, Yakutia 24 TV channel reports with the reference to “Science in Siberia”.
Paleontologists are searching for microfossils – the microscopic fossilized organic residues, that may contain mushrooms, in Precambrian deposits that existed previously 541 million years ago. Petr Kolosov, Doctor of Geological and Mineralogical Sciences, Chief Researcher of SB RAS, made a series of findings of well-preserved microscopic aquatic mushrooms in columnar stromatolites in Yakutia.
“Very ancient mushrooms in such preservation have never been found before in the world,” he noted.
In addition, the scientist discovered microorganisms of the same age, but of a different form: in the form of single cells that multiply by budding and division, which is typical for modern yeast. These paleo yeasts had characteristic root-shaped outgrowths, very similar to rhizoids – organs that serve to attach to the substrate.
“The Precambrian periods possess the roots of the Phanerozoic (that is, after 541 million years) and modern life, as well as the beginning of development of prehistoric and modern ecosystems. The discovery of well-preserved microfossils in the Precambrian sedimentary strata and the establishment of their systematic position (mainly bacteria, cyanobacteria, algae, fungi) can be considered an undoubted scientific achievement in understanding the early stages of the evolution of life,” Petr Kolosov explains.
