Abstract

The new data obtained on conodonts from the Lower Ordovician of the Kidryasovo, Akbulaksai, and Kuagach formations (the central part of the Sakmara Zone of the Southern Urals) allow to evaluate the biogeography of conodonts of this region. The comparison of conodont assemblages of the Southern Urals with well-studied conodont assemblages of the Baltoscandian Basin situated in the northwestern part of the East European Platform show that these assemblages were biogeographically isolated. This shows that basins of the central and eastern parts of the East European Platform were separated by land in the Early Ordovician.
