Microfossils of the late proterozoic debengdinskaya formation of the olenekskiy uplift

Abstract

Microfossils from the Middle Riphean Debengdinskaya formation of the Olenekskiy uplift have been studied. Various stenoorganic forms of acritarchs and cyanobacteries are described. Morphological groups which are preliminary compared with large flora taxons are allocated among acritarchs : brown and green seaweed, mushrooms, seaweed located in symbiotic relations (?) with cyanobionts. The prematurity of radical conclusions about age of the deposit based on majority of Proterozoic microfossils is underlined
