New Species of the Superfamily Palaeotextularioidea Galloway (Foraminifera) from the Upper Visean–Serpukhovian (Lower Carboniferous) of the East European Platform
Sakhnenko K.V.

Foraminifera of the superfamily Palaeotextularioidea Galloway, 1933 from the Upper Visean–Serpukhovian of the Moscow syneclise and Volga-Ural anteclise, that play a significant role on biostratigraphy and interregional correlation of the Lower Carboniferous of Eurasia, have been studied. Seven new species are described: Consobrinellopsis angustocuneata sp. nov., C. mstikhinensis sp. nov., Koskinotextularia densissima sp. nov., K. tumidaeformis sp. nov., Palaeotextularia cylindrica sp. nov., Cribrostomum planocameratum sp. nov., C. alekseevi sp. nov.

New Bivalves of the Genus (Pectinida, Streblochondriidae) from the Permian of Northeast Russia
Biakov A.S.

The problems of taxonomy of Permian pectinoid bivalves are briefly considered in the context of the study well-known Upper Paleozoic genus Streblopteria M’Coy and its historical development in Northeast Russia. Two new stratigraphically important species have been described from the Lower and Middle Permian deposits of the Omolon massif: S. parenensis sp. nov. and S. gracilicosta sp. nov.

Miocene Amathinidae (Gastropoda) of the Eastern Paratethys
Guzhov A.V.

Review was made for the Tarkhanian and Chokrakian representatives of the family Amathinidae. Two genera were defined—Leucotina and Carinorbis. The species L. ventosa (Bajarunas, 1910), L. belskayae (L. Iljina, 1993), L. costata sp. nov., L. excussa sp. nov., L. ovata sp. nov. and L. ovatoides sp. nov. were described in a composition of the genus Leucotina. L. ventosa is known from the undoubted Tarkhanian and continues to live in the Chokrakian, whereas the rest species were collected from the Chokrakian only. Relationships between the species of Leucotina remain unclear, although they can be divided into several morphological groups. It is concluded that a Chokrakian biodiversity of the genus is result of earlier (Tarkhanian) prehistory of Leucotina. Genus Carinorbis is represented by the rare and juvenile shells, which occur in uppermost Tarkhanian and in lower Chokrakian. The shells were determined as a species C. clathrata (Philippi). A proposal was made that Carinorbis not had a reproducing population in the Eastern Paratethys, but its founds is a result of bringing of the larvae from the neighboring bassins (Central Paratethys or Mediterranean).

On the Some (Ammonoidea: Parkinsoniidae) from the Uppermost Bajocian of the Kuban and Urup Rivers Interfluve (Northern Caucasus, Russia)
Mitta V.V.

Representatives of the genus Parkinsonia were studied using new material from the upper part of the Bajocian Parkinsoni Zone (Middle Jurassic) of Karachay-Cherkessia. Ammonites were found ex situ in the stratotype section of the Djangura Formation (southern slope of Dzhangura Mountain). The species P. perplanulata Wetzel [m], P. wetzeli Schmidtill et Krumbeck [m], P. cf. parkinsoni (Sowerby), P. cf. friedericiaugusti Wetzel are identified and partly illustrated. P. pseudoplanulata Besnosov [M, m], which was originally established only on macroconchs, is redescribed.

The First Finds of Representatives of the Order Acrotretida Kuhn from the Frasnian (Upper Devonian) Deposits of Komi Respublic
Smirnova T.N., Zhegallo E.A.

The structure and microstructure of the shell substance Acrotretella sp. on the protegulum, brephic and adult shell. The structure of the secondary layer, represented by interlayers with columnar-lamellar and spherulite structures, is characteristic. Wrinkles are developed along the edges of the shell.

Revision of Permosialidae (Insecta: Palaeomanteida) from Uppermost Lower and Lower Middle Permian of European Russia
Aristov D.S., Rasnitsyn A.P.

Generic and species composition of Permosialidae (Insecta: Palaeomanteida) from the uppermost Lower and lower Middle Permian of European Russia is discussed. Permosialis defurcata Martynova, 1952, P. brevifurcata Martynova, 1952, P. bifasciata Martynov, 1933, P. cauleoides Martynova, 1952, P. marmorata Martynova, 1952, P. immaculata Martynova, 1952 and P. fasciata Martynova, 1952 (all from the Lower Kazanian deposits of Soyana in Arkhangelsk Region) are synonymized under P. paucinervis Martynov, 1928 from the coeval deposits of Tikhie Gory in Tatarstan. Permosialis quadriramosa Martynova, 1952 from Soyana is synonymized under Palaeomantopsis furcatella Martynov, 1928 from Tikhie Gory. Palaeomantopsis furcatella, Permosialis paucinervis, P. perfecta Martynova, 1952, and P. latiformis Martynova, 1952 (the latter two from Soyana) are redescribed. Permosialis vizzya sp. nov. from Upper Kungurian of Vorgashor coal field and P. martynovae sp. nov. from Soyana are described as new.

A new species of horse mackerel fish of the genus (Carangidae, Percomorpha) from the Lower Oligocene of the North Caucasus
Bannikov A.F., Erebakan I.G.

A new species of horse mackerel fish (Carangidae), Archaeus solus sp. nov., was described based on the imprint of a complete skeleton from the Lower Oligocene (Pshekha Formation) of Gorny Luch locality. This is the third known species of the Eocene–Oligocene genus Archaeus Agassiz, 1844, and the first discovery of Carangidae in the Oligocene of the North Caucasus. The new species differs from A. glarisianus Agassiz, 1844 from the Rupelian of Switzerland and A. oblongus Daniltshenko, 1968 from the basal Eocene of Turkmenistan by a larger number of rays in both the spiny and soft dorsal fin.

The Discovery of Diadectomorph Tetrapods in the Lower Permian of Eastern Europe
Bulanov V.V.

The systematic position of the bolosaurid Stephanospondylus (Bolosaurus) traati (Tatarinov, 1974) is reassigned to the family Diadectidae (Diadectomorpha). This taxon is the first diadectomorph described from the Eastern Europe. Simple shape of the cheek teeth, as well as the pattern of the tooth differentiation along the maxilla indicate the basal position of S. traati within Diadectomorpha and its primitiveness in comparison with the type species to the genus Stephanospondylus, S. pugnax. The genus Ambedus Kissel et Reisz, 2004 is excluded from the order Diadectomorpha basing on the discrepancy of its marginal dentition to that of the other species of the group. The similarity of the dental system of Ambedus and diadectids is regarded as convergent rather than being due to its phylogenetic position, thus, the systematic position of this genus remains uncertain. The early stages of specialization of the dental system in the evolution of the family Diadectidae are discussed.

A Sea Turtle Nessov, 1987 from the Lower Paleogene Deposits of the Kudinovka Locality (Rostov Province, Russia)
Zvonok E.A., Benitskiy K.S., Danilov I.G.

The article describes fossil remains of turtles from the Kudinovka locality (Paleogene, Paleocene or Ypresian; Millerovo District, Rostov Province, Russia). These remains, represented by 16 specimens, are referred to the sea turtle Tasbacka aldabergeni Nessov, 1987 (Cheloniidae), previously reliably known only from the type locality Zhylga 1 (Paleogene, Late Thanetian–Early Ypresian; southern Kazakhstan). One of the described specimens represents the most part of the postcranial skeleton in the phosphate nodule and appears to be the most complete postcranial specimen of Tasbacka aldabergeni, which gives information about previously unknown details of morphology of this species. The new materials expand our knowledge of the geographical distribution of Tasbacka aldabergeni and the genus Tasbacka in general.

Green Algae of the Vendian (Ediacaran) Berezovsky Trough (South of the Siberian Platform)
Kolosov P.N.

Microorganisms of unique preservation were found in the Byuk formation of the Vendian (Ediacaran) of the Berezovsky trough in the southeast of the Siberian platform. These microorganisms are present in the silicified colloform stromatolites, i.e. they inhabited the littoral and sublittoral zones. The microorganisms are characterized by a lamellar body-type, rods between plates that attach them, and reproductive organ on the stipe. Based on these characteristics typical of Ulvaceae, the described microorganisms are to be representatives of green algae (Chlorophyta), belonging to the order Ulvales Blackman et Tansley, and presumably corresponding to the family Anchicodiaceae Shuysky, 1987. A new genus Palaeoulvaria with the type species P. plate gen. et sp. nov. was identified.
