MARINE MOLLUSKS OF ATLANTIC ORIGIN FROM THE PLIOCENE – EOPLEISTOCENE DEPOSITS IN WESTERN RUSSIAN ARCTIC AND THEIR BIOSTRATIGRAPHIC SIGNIFICANCE.

MOLLUSKS OF Astarte, Cyrtodaria, Mya, Panomya genera

In this article six fossil species of marine bivalves are described for the first time from Russia, including one new species and one subspecies: Astarte incerta Wood, A. paihoicus sp. nov., Сyrtodaria angusta (Nyst et Westendorp), Mya schwarzbachi Strauch, M. gudmunduri jugorica subsp. nov., Panomya obliquelongata Strauch. They were collected in the Zanclean – Calabrian Stages of the western part of the Russian Arctic. These molluscs have important significance for the Pliocene – Eopleistocene deposits in western part of the Russian Arctic and may be used for correlation of localities from the collecting area with the North Sea Basin.
