On the upper boundary of the eifelian stage in the Urals based on the fauna of quadrangular corals

Abstract
Recently, the question of the upper boundary of the Eifelian Stage in the Urals has become more acute. Two All-Union meetings (in Sverdlovsk in 1957 on the unification of stratigraphic schemes of the Urals and in Leningrad in 1958 on facies maps of the Devonian period) made two different decisions on this question. In Sverdlovsk, it was decided to assign the Calceolian and Biysky layers on the western slope and their analogs on the eastern slope to the Eifelian Stage. In Leningrad, the decision of the 1951 All-Union meeting on the development of a unified scheme of Devonian stratigraphy was left in force.
