Abstract
Stratigraphic assemblages characteristic for the Ordovician, Silurian, Devonian, Carboniferous, and Permian are presented based on the analysis of newly refined and supplemented data on the composition and distribution of Paleozoic bryozoans in Mongolia. Thirty-four auxiliary biostratigraphic units ranked as beds with bryozoans are established in order to subdivide the Paleozoic strata of Mongolia.
