Frondicularies (Foraminifera) from Triassic deposits of North Siberia and the Kotel’ny Island (New Siberian Islands)
摘要
A monographic study of representatives of the genus Frondicularia (Foraminifera) from the Middle-Upper Triassic deposits of the north of Central Siberia and Kotel’ny Island was carried out. A complete description of one new species (Frondicularia arctica sp. nov.) and a brief description of seven previously known species are presented. The variability of morphological features of species was compared using mathematical methods such as regression analysis, parametric statistical methods and multivariate analysis (principal component method). Evolutionary changes in the structure of the initial part of the shell and form of the proloculum from oval to fusiform in three species assignment assigned to the same phylogenetic lineage (F. lepidaeformis Yadrenkin – F. foliacea Yadrenkin–F. phyllodeaeformis Yadrenkin).

Revision of the family Tetrentactiniidae Kozur et Mostler, 1979 (Radiolarians of the Late Paleozoic). Part 1. Family, subfamilies
摘要
The family Tetrentactiniidae Kozur et Mostler, 1979, is revised and its diagnosis and generic composition are emended. The subfamily Tetrentactiniinae Kozur et Mostler, 1979, stat. nov., is revised, and its rank is emended. The new subfamily Uralitininae Afanasieva et Gainullina, subfam. nov. is established. A diagnosis of a new genus and new species Uralitina megalospina gen. et sp. nov. is given. The validus status is restored for the genus Triaenoentactinosphaera Wang, 1997.

New Radiolarian Species of the Genus Rhopalosyringium Campbell et Clark from the Maastrichtian Deposits of Lefkara Formation, Cyprus
摘要
Numerous representatives of the genus Rhopalosyringium Campbell et Clark, 1944 were studied from the Upper Cretaceous (Maastrichtian) deposits of the Lefkara Formation (Cyprus). New species R. lefkaraense sp. nov., R. longum sp. nov. and R. triporosum sp. nov. are described.

New genus and species of the Early Cretaceous radiolarians of the family Echinocampidae in the Western Siberia and Volga Basin
摘要
As a result of studying the Jurassic-Cretaceous radiolarians of Western Siberia and Volga Basin, numerous representatives of the family Echinocampidae Bragin, 2009 were discovered. A new genus Spinicapsa gen. nov., its type species S. gatovskii sp. nov., as well as a new species Arctocapsula kalmikovi sp. nov., have been described from the carbonate-siliceous deposits of the upper Bazhenov Formation (Volgian–Rjazanian Regional Stages = = Tithonian–Berriasian Stages) of Western Siberia. The diagnosis of the genus Arctocapsula Bragin 2009 was clarified, Arctocapsula aculeata sp. nov. described from the clay deposits of the Subditus zone in Volga River Basin.

New Species of Bivalves of the Genus Lopatinia (Arcoidea, Cucullaeidae) from the Upper Jurassic of Northern Siberia
摘要
New species Lopatinia (Lopatinia) prima sp. nov. has been described from the upper Oxfordian – lower Kimmeridgian deposits of Northern Siberia (Anabar River basin). The diagnosis of the genus Lopatinia as well as its stratigraphic and palaeobiogeographic distribution have been clarified. The boreal basins of Europe (most likely, the Russian Sea) were the center of the origin of the genus. Later, representatives of the genus spread to the Arctic basins as well as to the Southern hemisphere in the Notal Superrealm. Already in the early Kimmeridgian the genus Lopatinia had a bipolar distribution.

A New Species of the Genus Tainoceras (Nautilida) from the Lower Carboniferous of the Moscow Syneclise
摘要
A representative of the genus Tainoceras (order Nautilida family Tainoceratidae) from the Lower Carboniferous (Protvian) of Moscow Syneclise is described for the first time. Until now, the earliest records of this genus were known from the Middle Carboniferous of North America, while on the Russian Plate, the only species known was T. trautsholdi (Waagen, 1879) from the Gzhelian Stage. The studied material enabled a complete description of the new taxon Tainoceras vashutinense sp. nov. Thus, the new find made it possible to expanding the boundaries of the stratigraphic and geographic distribution of this nautilid genus.

The Genus Spiroceras (Ammonoidea) from the Upper Bajocian of the Northern Caucasus: Intraspecific Heterochronies
摘要
This paper discusses records of heteromorphic ammonites of the genus Spiroceras (family Spiroceratidae) in the Upper Bajocian of the interfluve of the Kuban and Urup rivers (Karachay-Cherkessia). The presence of a single species, S. obliquecostatum (Quenstedt), has been confirmed for the lower part of the Parkinsoni Zone (sherstyukovi faunal horizon). S. obliquus (Baugier et Sauzé) is identified for the first time from the upper part of the Niortense Zone (bispinatum faunal horizon). The most abundant and well-preserved material (also from the bispinatum horizon) consists of the species S. annulatum (Deshayes) and S. bispinatum (Baugier et Sauzé). Among the adult shells of these two species, two size groups are clearly distinguished, characteristic of both microconchs and macroconchs. Apparently, this is a classic case of intrapopulation heterochrony, expressed in the presence of normogerontic and tachygerontic shells.

Burrows of the polychaetes Lepidenteron lewesiensis (Mantell, 1822) from the Upper Cretaceous of the Lower Volga Region
摘要
Burrows of the predatory polychaete Lepidenteron with scales and bones of small teleost fish are first discovered in the marine Upper Cretaceous (Turonian-Maastrichtian) of the Lower Volga region. All these burrows have a similar structure and belong to the ichnospecies Lepidenteron lewesiensis. Bone remains and scales of teleost fish belonging to four taxa were found in the burrows: one Teleostei indet., two Clupeocephala indet. and one Dercetidae gen. indet. New finds of L. lewesiensis expand the paleogeographic distribution of the considered ichnogenus and ichnospecies in the Late Cretaceous and complement our understanding of the Late Cretaceous marine paleoecosystems of this region.

Postcranial osteoderms of Late Permian pareiasaurs from Eastern Europe – II. Genera Deltavjatia, Proelginia, Senectosaurus, Scutosaurus, Obirkovia
摘要
The results of comparative morphological analysis of the postcranial osteodermal cover of East European pareiasaurs Scutosaurus karpinskii (Amalitzky), S. tuberculatus (Amalitzky), S. itilensis Ivachnenko et Lebedev, Deltavjatia rossica (Hartmann-Weinberg), Proelginia permiana Hartmann-Weinberg, Obirkovia gladiator Bulanov et Jashina, and Senectosaurus karamzini Boyarinova et Golubev are presented. It has been established that postcranial osteoderms are an important diagnostic material that allows identifying taxa of generic and species ranks. All known pareiasaur genera differ fundamentally from each other in the structure of the osteodermal cover. The validity of the genus Proelginia has been confirmed. The diagnoses of the East European pareiasaur genera and species are supplemented by osteodermal cover characteristic features.

New Dispersed Cuticles and Conifers from the Upper Kazanian Sediments of Udmurtia
摘要
The article describes remains of fossil plants first discovered in the Late Kazanian localities Chepanikha and Kostovaty in Udmurtia: Sashinia antiqua, Geinitzia sp. and Taenimacutis gomankovii gen. et sp. nov. The new finds allowed to compare the Late Kazanian flora of the Udmurtia Kama region with the close in age floras of the Southern Urals more accurately and to extend the characteristics of the Kostovaty floristic assemblage, which characterizes the Late Kazanian sediments of the East European Platform.
