Abstract
A new assemblage of Early Vendian (Middle Ediacaran) microfossils, including acanthomorphic acritarchs and various filamentous remains, as well as sphaeromorphic striated vesicles of Valeria, which are not characteristic of deposits of this age, is described in the Ura Formation of the Dal’nyaya Taiga Group of the Patom Basin. A new species of acanthomorphs Hocosphaeridium crispum sp. nov. is described. The selective confinement of the Ediacaran eukaryotic phytoplankton taphocoenoses to the open-sea proximal facies of the inner ramp is shown.
