Fossil Organisms of the Redkino Regional Stage of the Upper Vendian of the Northwestern Russian Platform (Leningrad Region)

The taxonomic diversity and vertical distribution of micro- and macroscopic fossil organisms are analyzed. The depositional settings of the Upper Vendian Staraya Russa (=Starorusskaya) Formation in the northwest of the Russian Platform are reconstructed. We identified two assemblages of Redkino age with Tynnia precambrica–Zinkovioides inclusus and Orbisiana simplex–Doushantuophyton lineare. A new genus and species of acanthomorphic acritarch, Tuberculum mamillatum gen. et sp. nov., is described
