Three new species and two new genera of scleractinian corals are described from the upper Oxfordian (Jurassic) limestones of Azerbaijan. Cyathopora parva, Thecosmilia vurguni, and Thecosmilia zagaliensis are described as new. The genus Brevimaeandra (Type species: B. alizadei nov. sp.) is compared with Mycetophyllopsis and Maeandrastraea, and is placed in the Family Montlivaltiidae. Grandifavia (Type species: G. bendukidzeae, nov. sp.) is placed in the Family Faviidae and is compared with Favia and Nefocoenia. No other constituents of the fauna are listed nor are references to such lists given. A brief introduction states that the limestones of middle Oxfordian age are probably reworked reef deposits, and that the coral and sponge reefs were deposited in waters probably not over 90 m deep. No stratigraphic sections are given. — D. F. Squires.  相似文献

Ammonoids of early Upper Scythian age are described from three localities in the Northern Caucasus. No data on relative stratigraphic position is given, but some forms are common to the different exposures and the author concludes that all the ammonoids are Upper Scythian (Olenekian). Affinites with Pacific faunas are stressed and the faunules are correlated with the Owenites zone of North America. Two new genera (Parinyoites and Subowenites) and three new species (Dieneroceras caucasicum, Parinyoites ,mastykensis, Subovvenites slavini)are proposed. Flemingites pulcher Waagen, Wyomingites aplanatus (White), Parussuria compressa (Hyatt and Smith), and Owenites koeneni (Hyatt and Smith) are described and figured. Parinyoites differs from Metinyoites in having rounded saddles and it lacks the keel and costation of Inyoites. Subowenites has reticulate ornamentation, unlike Owenites, Parowenites, and Pseudowenites; it also lacks the adventive notches in the median saddle of Pseudowenites. --E. T. Tozer.  相似文献

The foraminifer Tournayella Dain, 1953, formerly believed to be restricted to the Tournasian, is found in the upper part of the Frasnian, western Ural Mountain province. The Frasnianform is a subgenus of Tournayella and is here named T. (Eotournayella) jubra, n. sg., n. sp., monotypic. Eotournayella seems to be transitional from the ammodiscids to the tournayellids and to be ancestral to or to contain marks of characteristic structures in certain tournayellid stocks.—L.G.

The late Paleozoic genus Praehorridonia and its type species is described, differing from Horridonia by presence of radial and concentric sculpture and by absence of spines on the brachial valve. The author believes the large Praehorridonia possessing traces of semireticulate structure, descended from the strongly semireticulate Antiquatonia in Middle Carboniferous and evolved into Horridonia, thus representing an intermediate stage between Antiquatonia and Horridonia. The family was confined to the Arctic throughout its history and became extinct in the middle of the Upper Permian. -- G. A. Cooper.  相似文献

Representatives of the bryozoan family Rhabdomesidae (the family name and derivatives, misspelled throughout the original version, are corrected in this translation), found in the Lower Kazanian deposits of the Russian Platform and the Upper Permian of the Little Caucasus and of Transcaucasia are described as new species of Rhabdomeson, Rhombopora, and Neorhombopora, n. gen. Rhombopora crassa Ulrich, 1884, from the Upper Carboniferous (Upper Pennsylvanian) of North America, is designated the type species of Neorhombopora, which is characterized by spiral budding in ihe axial zone and by the absence of megacanthopores. Although only three genera and four species of rhabdomesids are recognized in the Upper Permian of the Soviet Union, specimens are comparatively abundant, and the species seem to be good index fossils. Rhabdomeson noinskyi was identified from various localities in the Lower Kazanian of the Vyatka and Nemda river basins; Rhabdomeson floriforum occurs in the Upper Permian Gnishik suite at several localities in Transcaucasia; Rhornbopora ornata is known from the Lower Kazanian of Kirov and Arkhangel'sk Provinces, Komi ASSR; and Neorhombopora polita was found at one locality in the Lower Kazanian of Kirov Province.—H.

Bogoslovskiy describes the first known occurrence of Early Devonian ammonoids in the Soviet Union. These indicate that the sediments in which they occur are Coblentzian in age and not Givetian as previously thought. The author reviews the higher taxonomic categories used for early ammonoids, and places his materials in the genera: Erbenoceras Bogoslovskiy, Mimosphinctes Eichenberg, Teicherticeras (Teicherticeras) Erben, and Teicherticeras (Convoluticeras) Erben. — John Pojeta, Jr.  相似文献

Valanginian marine sediments are widespread in the eastern margin of Asia from China northward over the Sikhote-Alin region, as far west as the Amur river, and as far north as the Amgun river. This was an interior type sea with abundant islands and a boreal fauna. It is surmised that Kamchatka, Sakhalin, Hokkaido, and the other Japanese islands were not invaded by the sea. A paralic coal basin is known on southwestern Honshu. Post-Valanginian folding and erosion preceded a Barremian-Albian marine transgression over the same general area. In these younger Cretaceous rocks southern faunas appear and the boreal fauna is present north of 45° latitude. Aucella and Aucellina species are important elements of the faunas. This review of faunas and correlations, including western North America, suggests that Hauterivian folding was a major event in North Pacific tectonic history. -- C. G. Tillman.  相似文献

A new graptolite genus is described from lower Wenlockian rocks on the Molyud-Vozh river in the northwest Urals. Uralograptus closely resembles Cyrtograptus but lacks the spiral coiling of the main part of the rhabdosome. U. insuetus, the type species, was collected from the zone of Oktavites spiralis (Geinitz). --B.S. Norford.  相似文献

Tubes situated at the angles between corallitis in favositids have already been recognized as symbiotic organisms, and several genera are known. A new genus, Actinosalpinx, having a threerayed form in cross-section, is described. It is associated with Lower and Middle Devonian Favosites species. Antherosalpinx is proposed for another Devonian form with four- to eight-rayed cross-section. Such forms are believed to belong to a group of symbiotic annelid worms.-- D. J. McLaren.  相似文献

Vernadskiy's views on the origin of oil, as originally expressed in 1924 in the first French edition of Geochemistry and more extensively in his Essays in Geochemistry (especially in the fourth or second Russian edition, 1934), are evaluated and praised in light of more recent information. The principal reference is the second Russian edition, in six essays. The several points of Vernadskiy's thesis, that oil is of organic origin, are noted and discussed with reference to data more extensive than that available to him. Vernadskiy's interest in the origin of oil was subordinate to his major interest in the geochemistry of carbon and its history in the crust, and in biogeochemistry — the role of living matter in the development of the upper geosphere. To him the emergence of oil was “one of the momentous manifestations of a transfer of solar energy to deeper reaches of our planet, by means of living substance.” Vernadskiy, in light of Trask's work, even conceded the possibility of oil originating from organic matter of continental fresh-water basins. He read widely in his field and appreciated the need for understanding the history of thought on the subject. The organic theory, he strongly believed, was born in 1763 with the publication of Lomonosov's On Terrestrial Layers. — W.D. Lowry.  相似文献

Two new species of Early Carboniferous colonial Rugosa discovered in collections from the western slopes of the Central Urals provide additional data on geographic ranges of Aulina and Paralithostrotion. Aulina kosvensis is the first fasciculate species of the genus to be described from the U. S. S. R. It was found in the Upper Viséan Ladeininskii horizon. Paralithostrotion talkaense is described on material from the Ladeininskii and Ust'sarbaiskii horizons and considered to be of upper Viséan(?) and Namurian age. In connection with this investigation, the type material of Paralithostrotion jermolaevi Gorskiy and Tschernowiphyllum podboriense Dobrolyubova, which are the type species of the two genera, was restudied and found to be congeneric. Tschernowiphyllum Dobrolyubova, 1958, is therefore a junior synonym of Paralithostrotion Gorskiy, 1938. As revised, Paralithostrotion is considered to be a doubtful lithostrotionid lacking a genuine columella and having tabulae that are concave to horizontal. The corallum is fasciculate with connecting processes, which open into a corallite at one end but at the other terminate blindly against a neighboring corallite. Two opposing septa are longer than the other majors and generally overlap in the axial region. The dissepimentarium is narrow and may not be developed. - H. Duncan.  相似文献

Belemnite rostra bear longitudinal furrows of various kinds, ranging considerably in strength. The present systematic classification of belemnites is based on characters other than the generally indistinct marginal or lateral furrows which, nevertheless, are important because they probably are attachment scars for the fins. One reason for their neglect by taxonomists in belemnite classification is that they are not useful for differentiation of genera, but tend to remain fairly constant within the subfamily. A study of several thousand specimens shows that Cylindroteuthis and Pachyteuthis, represented by 13 species, have a similar pattern of lateral grooves and belong in the same subfamily (Cylindroteuthinae). A different pattern common to Aulacoteuthis and Oxyteuthis shows that these genera were correctly united by Stolley in a different subfamily (Oxyteuthinae). Attention to details of the lateral grooves will also permit working out the phylogeny of major stocks, such as the descent of Belemnitellinae from the Belemnopsinae, confirmed by the present study.--Mackenzie Gordon, Jr.  相似文献

A new species of Caytonia, C. orientale, and a new genus and species Chankanella vachrameevi are described from Neocomian-Aptian coal bearing strata in the Primor'ye Territory, Suifun basin. The new species of Caytonia is differentiated from C. sewardii Thomas and C. canadensis (Berry) Bell on the basis of size and slight morphological variances. Only one specimen of a megasporophyll was available for study. Leaves found in the same stratum and attributed to the new species differ from other species of Sagenopteris chiefly in the greater length of the petioles of the leaflets. Chankanella vachrameevi is described as a Sagenopteris-like leaf. It differs from Sagenopteris in having a larger number of leaflets and in lacking anastomoses of veins in the leaflets. It is compared with Lesleva Lesquereux. Its leaflets are compared with Thinnfeldia pinnae, and the leaves of Tersiella Radczenko, Linquifolium and Protophyllocladus. — F. M. Hueber.  相似文献

Six new species of the genus Bythocytheremorpha, including B. centroscrobiculata, B. aksuensis, B. bicornis, B. (?) abnormis, B. torulosa, and B. ilyini, are reported and described from beds of Upper Cretaceous age (Cenomanian through Santonian) of the southwestern part of the Gissar Range, located in the southeast of Soviet Central Asia. These relatively primitive Cretaceous ostracods, which possess an intricately sculptured carapace, seem to have lived in a shallow, warm, marine environment. — R. H. Benson.  相似文献

The new genus Daubichites (Paragastrioceratidae) includes involute, broadly discoidal shells with fine reticulate surface ornamentation, plicate or tuberculate umbilical shoulders on the early volutions, a suture line with 8 lobes, and a ventral sinus reflected in the growth line and septal necks. Two species are presently included in the genus, Daubichites goochi (Teichert) from the Upper Permian of Western Australia, and D. orientalis Popovsp. nov. (the type species here described) from the Upper Permian of the Sikhote-Alin' Range, Maritime Coast region (Primor'ye). In addition, certain pseudogastrioceratid species from the Phosphoria and Kaibab Formations of North America may belong to this genus. Daubichites is important to the phylogenetic study of the Paragastrioceratidae because it is transitional between Early Permian forms which possess a ventral projection and Late Permian forms with a ventral sinus. Daubichites is possibly descended from Tumaroceras. — Erle Kauffman.  相似文献
