The stages of сalcareous Algae development in the Urals during Devonian
Abstract
The article highlights the following stages of the development microscopic Devonian Algae in the Urals: the rise of Algae in the early Devonian (Karpinski time), degradation of Algae flora during the end of Early Devonian (taltiysk time), the Middle Devonian and Early Frasnian; Late Frasnian is the time of flowering Cyanobacteria, Green Dasycladales Algae, Red Algae and extinction of Green Siphonales Algae. Degradation of Algae in the Early Famennian time. Late Famenian - is the flourishing at the development of Green and Red Algae, especially Green Siphonocladales Algae.Type material is deposited at the Ural Geological Museum, Ekaterinburg, UGM collection № 10-91 and in the Stratigraphy and Paleontology laboratory of the Institute of Geology and Geochemistry, Urals Branch of the RAS, Ekaterinburg.
