Abstract
Three new sites of faunal remains in the Middle Carboniferous (Lower Pennsylvanian) deposits of the Donets Basin were studied. They are confined to shale in the lower part of the Mospino Formation (Upper Bashkirian) and are located in the south part of the Lutuginsky district of the Luhansk region. Of these deposits set allochthonous remains of terrestrial plants, as well as allegedly Pogonophora, cnidarians Sphenothallus, inarticulate brachiopods Lingula and uncertain productids, numerous pelecypods Nuculopsis, Palaeoneilo, Phestia, Posidoniella, Sanguinolites, Solenomorpha, Euchondria, as well as a variety of cephalopods and phyllocarids Dithyrocaris. Remains often have very good preservation, which largely determines the value of the studied outcrops. Attention is drawn to the wide development of formations identified as bromalites. In the collection there is also a single bromalite, almost entirely consisting of ammonitellas. In addition, there are many fossils in the studied collection whose systematic affiliation is not clear. The lower part of the shales was formed, apparently, in the conditions of the upper part of the shelf, in the basin with a quiet hydrodynamic regime and hydrogen sulfide contamination of the bottom waters and/or part of the bottom sediments. The rest of the described strata was formed in prodeltaic conditions.
