Geological journal| Резюме: | New finds of fossil assemblages of brachiopods, mollusks, crinoids, arthropods and fishes, as well as terrestrial plants from a part of the Dyakove Group, which corresponds to the coal-bearing Mandrykyne Formation and the lower part of the Mospyne Formation and is exposed in the southern part of the Luhansk Region, were studied. For the first time, a brachiopod assemblage consisting of species of the genera Crurithyris, Tiramnia, Alphachoristites, Lissochonetes were identified in these rocks. In addition, phyllocarids and impressions of terrestrial plants of the genera Halonia, Calamites, Pinnularia, Paripteris, Eusphenopteris, Artisia and Cordaites were found in the Dyakove Group for the first time. Bivalves and gastropods in the studied collection are represented by the genera Phestia, Palaeoneilo, Nuculavus, Solenomorpha, Sanguinolites, Posidoniella, ?Euchondria, ?Nodospira, Euphemites, Retispira, Glabrocingulum, Rhineoderma, Angyomphalus, and Naticopsis. Cephalopods are represented by the species of the genera Gzheloceras, ?Pseudogzheloceras, Melvilloceras, Retites, Gastrioceras and ?Owenoceras. In addition to the above groups, the rocks also contain the crinoids Platyplateium, Platycrinites, ?Unilineatocrinus and Bicostulatocrinus as well as fragments of fin spines of acanthodians Gyracanthidae indet. and isolated unidentified fish scales. |
