Abstract
Paleontological evidence of the presence Wordian bivalves in the Middle Permian deposits of the Omolon massif, originally described by N. Newell from the Wordian Formation of the Glass Mountains (West Texas), is presented for the first time. In the Kolymia multiformis bivalve Zone of the Bocharian Regional Horizon, pectinids of the genus Heteropecten – H. gyrtyi (Newell) and H. gryphus (Newell), were found, which allow this Zone to be confidently correlated with the Wordian Stage of the International Stratigraphic Scale (ISS) of the Permian and indicate the relationship of the Kolyma-Omolon basins with the North American basins.
