Silurian brachiopods of the Sette-Daban Ridge (South Verkhoyansk area) and their paleogeographic ties
Abstract
Silurian brachiopods collected over the years from 10 outcrops of the Sette-Daban were first analyzed. The monotonous assemblage of the Tayakhsky Formation (Lower Silurian) represented by pentamerids, atrypids, rhynchonellids is characterized by mixed systematic composition similar to assemblages studied from sediments of the same age in the Siberian platform, Taimyr and North-East of Russia that confirms paleogeographic relations of the Silurian basins in the Early Silurian.
