摘要

The study of organic films from Zimnie Gory Beds, Ust'-Pinega Formation (Upper Vendian) permits to identify numerous colonial coccoid cyanobacteria of genus Ostiana Hermann (O. microcystis and O. aphanotece sp. nov.). Spheroid acritarchs of genus Leiospheridia Eis. (L. tenuissima and L. ternata) are occasionally found together with the colonial microfossils. Pyritized organic films with filamentous Leiotrichoides tipicus were found in some layers of Ust'-Pinega formation.
