The Kamenka Bay horizon is the lowest regional stratigraphic unit of the Devonian on Novaya Zemlya. Within the southern part of the archipelago (Vaigach-Yuzhno-Novaya Zemlya structural-facial zone) it includes a thick (700-1000 m) stratum of terrigenous-carbonate formations, which is divided into three formations (from bottom to top): the Propaschinskian, West Nogorskian and Karandean.

The fauna of quadrangular corals from Devonian sediments of Novaya Zemlya is rich and diverse. However, it is described extremely insufficiently and unevenly, both stratigraphically and geographically by A.G. Kravtsov and E. 3. Bulvanker studied mainly solitary forms belonging to the families Tryplasma- tidae, DigonophYllidae, CYstiphyllidae, Zonophyllidae, Heliophyllidae, Stringophyllidae, and to a lesser extent colonial corals of the families Spongophyllidae, Billingsastraeidae, XYstriphyllidae from the Early and Middle Devonian sediments of the South Island ...
