SOME LOWER FAMENNIAN (UPPER DEVONIAN) CYRTOSPIRIFERID BRACHIOPODS FROM THE VOLHYN-PODILLIAN PLATE (WESTERN UKRAINE)

This study provides the first documentation of lower Famennian spiriferide brachiopods from the Volhyn-Podillian plate in western Ukraine, specifically from the Lokachi, Torchyn, Kowel’, and Velyki Mosty boreholes in the Volhyn and Lviv regions. The examined assemblage comprises three species: Cyrtospiriferinae gen. indet., Tornatospirifer sp., and Cyrtiopsis? sp. Albeit with some uncertainty regarding the latter genus, this marks the first record of these genera in Ukraine, thereby extending the palaeobiogeographic distribution of the subfamily Cyrtiopsinae.
