New investigations of Upper Devonian wood from the north of the European part of Russia

Abstract

The paper describes a continuation of our research on the distribution of archaeopteridalean plants in the north of the European part of the Russian Federation. New data on archaeopterid wood remains from Upper Devonian deposits of Northern Timan are presented. Representatives of the genus Callixylon are documented: the type species C. trifilievii, fragments of stumps (or root systems) with C. zalesskyi wood, and a small branch of C. sp.
