NEW SPECIES OF SPIRIFERIDS (BRACHIOPODA) FROM THE DEVONIAN AND CARBONIFEROUS OF EASTERN EUROPE

Abstract

In a revision of previously published materials, two new spiriferid species from the Late Tournaisian, Unispirifer subtornacensis sp. nov. and Mesochorispira ussuilensis sp. nov., and Atylephorus nalivkini sp. nov. from the Lytva Horizon of the Upper Devonian of Bashkiria are described. Based on the original collection, a new Serpukhovian subspecies, Podtsheremia duplicicosta triplicicosta, from the southern Ural Mountains and a new Late Carboniferous species, Purdonella kalashnikovi, from the polar Ural Mountains and adjacent islands are established. © Pleiades Publishing, Inc. 2006.
