The following paper describes the foraminiferal fauna and associated faunal assemblages of the bedded and reef carbonates of the Upper Triassic (most probably Rhaetian) Nayband Formation, which are exposed in a section south of the small town of Bagher-Abad, northeast of Esfahan. Foraminifers are extremely rare in sponge- or coral-dominated bioconstructions and in the bedded carbonates of the Nayband Formation in central Iran. Some carbonate beds are composed of bioclastic wackstone/packstone. These are exposed in the solenoporacean horizon at the uppermost part of the section. Here, the aulotortid- and trocholinid-type foraminifers are relatively abundant. The following foraminiferal taxa with different abundances were found within the carbonates of the investigated section: Trocholina umbo Frentzen, T. turris Frentzen, T. gracilis Blau, Aulotortus tumidus (Kristan-Tollmann), Aulotortus tenuis (Kristan), Aulotortus friedli (Kristan-Tollmann), Coronipora etrusca (Pirini), Semiinvoluta clari Kristan, Turrispirillina? licia variabilis Blau, Galeanella? laticarinata Al-Shaibani, Carter and Zaninetti, Ophthalmidium sp., Agathammina sp., “Sigmoilinaschaeferae Zaninetti, Planiinvoluta carinata Leischner, Planiinvoluta sp., Nubecularia sp., Endothyra sp., Paeolituonella sp. and some sessile agglutinated and nodosariid types. All mentioned taxa are very rare, except the involutinid and trocholinid types. The following species are described as new: Trocholina blaui nov. sp., Spirilina? iranica nov. sp., and Coronipora serraforma nov. sp. Trocholina blaui is usually attached to solenoporacean thalli. Four foraminiferal associations, which are named after the occurrence of the abundant species, were distinguished as Aulotortus tumidus association, Aulotortus friedli association, Trocholina umbo association, and Trocholina blaui association. Aulotortid types and Trocholina umbo were found within the bioclastic wackstone/packstone carbonates. Trocholina blaui is abundant in solenoporacean framestones. The foraminiferal association of investigated carbonates contains a mixed fauna, known from Upper Triassic–Liassic in the Tethyan realm. Carbonates of the whole investigated section are dated—due to occurrence of the genus Aulotortus, with species A. tumidus (Kristan-Tollmann), A. tenuis (Kristan), and A. friedli (Kristan-Tollmann)—as Upper Triassic (most probably Rhaetian). The “typical” foraminifers occurring in the reef biotopes in the northwestern Tethys are either missing or extremely rare in the Iranian bioconstructions.  相似文献

The following new species are described: Pseudethas jacobsoni sp. n. (India: Kashmir), P. kabakovi sp. n. (Afghanistan: Laghman Prov.), Dichillus kabakovi sp. n. (Afghanistan: Kandahar), D. kabulensis sp. n. (Afghanistan: Kabul), Microtelus zarudnyi sp. n. (Iran: Horassan; Afghanistan: Herat Prov.), and Microblemma kabakovi sp. n. (Afghanistan: Farah). Specific distinctness of Tagenostola pilosa Motsch. and T. turkestanica Rtt. is substantiated, and a new synonymy is established: Reitterella fusiformis Semenov, 1891 = R. gracillima Semenov, 1903, syn. n.; = R. turkestanica Pic, 1906, syn. n.  相似文献

Supercalcified sponges, including sphinctozoans, inozoans, chaetetids, spongiomorphids, occurring in Upper Triassic (Norian-Rhaetian) shallow-marine limestones of Musandam Mountains in United Arab Emirates (UAE), are described. The following taxa were determined: sphinctozoans: Hajarispongia osmani Senowbari-Daryan and Yancey, Nevadathalamia arabica n. sp., Nevadathalamia conica n. sp., Fanthalamia milahaensis n. sp., Iranothalamia incrustans (Boiko), Cinnabaria regularis n. sp.; inozoans: Cavsonella triassica n. sp., Molengraaffia regularis Vinassa de Regny, Peronidella? sp., Circopora cf. caucasica Moiseev, Circopora? sp.; spongiomorphids: Spongiomorpha sp.; chaetetids: Lovcenipora chaetetiformis Vinassa de Regny, Lovcenipora musandamensis n. sp., Lovcenipora sp., chaetetid sponge gen. et sp. indet. The most abundant sponge in the studied material is Nevadathalamia arabica n. sp. The described sponge association of the Arabian shelf (Musandam Mountains) shows close affinity to the sponge association known from age-equivalent terranes in the Panthalassa Ocean (Sonora Mountains in Mexico; Pilot Mountains in Nevada, USA), but is remarkably different from sponge associations in carbonates bordering the Tethys. This difference goes along with the biogeography of wallowaconchid bivalves and is most likely attributed to climatic, palaeogeographic or oceanographic factors.  相似文献

Triassic radiolarians from Kotel’nyi Island (New Siberian Islands, Arctic Region) are studied. Radiolarians occur in the Middle and Upper Triassic beds, which are well dated by ammonoids, nautiloids, and bivalves. In the Middle Triassic beds, which are composed of dark gray and black clays and claystones with interbeds of combustible schist, siltstone, clayey limestone, and many phosphatic concretions, the following two assemblages are recognized: (1) a Late Anisian assemblage, including Glomeropyle clavatum Bragin, sp. nov., G. boreale Bragin, G. manihepuaensis Aita, G. insulanum Bragin, sp. nov., Triassospongosphaera multispinosa (Kozur et Mostler), Tetraspongodiscus hibernus Bragin, sp. nov., T. borealis Bragin, sp. nov., Eptingium abditum Bragin, sp. nov., E. manfredi Dumitrica, Spongostephanidium japonicum (Nakaseko et Nishimura), and Ladinocampe vicentinensis Kozur et Mostler; (2) Late Ladinian assemblage, with Muelleritortis firma (Gorican), M. kotelnyensis Bragin, sp. nov., Tiborella nivea Bragin, sp. nov., Pseudostylosphaera goestlingensis (Kozur et Mostler), P. omolonica Bragin, Triassospongosphaera multispinosa (Kozur et Mostler), Sarla cincinnata Bragin, sp. nov., S. obscura Bragin, sp. nov., S. prava Bragin, sp. nov., and Eonapora stiriaca Bragin, sp. nov. The Upper Triassic beds, composed of gray and black clays and claystones with lenses of clayey limestones, with sideritic and phosphatic-calciferous concretions have yielded (1) an Early Carnian assemblage, with Pentactinocarpus colum Bragin, sp. nov., Glomeropyle cuneum Bragin, sp. nov., G. algidum Bragin, sp. nov., G. aculeatum Bragin, sp. nov., Kahlerosphaera isopleura Bragin, sp. nov., Stauracanthocircus folium Bragin, sp. nov., Tetraspongodiscus uncatus Bragin, sp. nov., Poulpus costatus (Kozur et Mostler), Eonapora robusta Kozur et Mostler, Planispinocyrtis kotelnyensis Bragin, sp. nov., Annulotriassocampe baldii (Kozur), and Pseudoeucyrtis annosus Bragin, sp. nov.; (2) a Middle-Late Carnian assemblage with Pseudostylosphaera glabella Bragin, sp. nov., P. gracilis Kozur et Mock, P. voluta Bragin, sp. nov., P. gelida Bragin, sp. nov., Kahlerosphaera unca Bragin, sp. nov., K. aspinosa Kozur et Mock, K. fuscinula Bragin, sp. nov., K. acris Bragin, sp. nov., Capnuchosphaera kuzmichevi Bragin, sp. nov., C. triassica De Wever, C. angusta Bragin, sp. nov., Sarla intorta Bragin, sp. nov., S. compressa Bragin, sp. nov., S. aequipeda Bragin, sp. nov., Betraccium irregulare Bragin, B. kotelnyensis Bragin, sp. nov., Spongotortilispinus carnicus Kozur et Mostler, S. subtilis Bragin, sp. nov., Dumitricasphaera simplex Tekin, D. aberrata Bragin, sp. nov., D. arbustiva Bragin, sp. nov., Zhamojdasphaera epipeda Bragin, sp. nov., Z. proceruspinosa Kozur et Mostler, Vinassaspongus subsphaericus Kozur et Mostler, Palaeosaturnalis triassicus Kozur et Mostler, Paronaella concreta Bragin, sp. nov., P. aquilonia Bragin, sp. nov., Tetraspongodiscus cincinnalis Bragin, sp. nov., Annulotriassocampe baldii (Kozur), Canoptum zetangense Wang et Yang, Whalenella speciosa (Blome), Syringocapsa turgida Blome, Droltus gelidus Bragin, sp. nov., and D. niveus Bragin, sp. nov.; (3) an Early Norian assemblage with Pseudostylosphaera glabella Bragin, sp. nov., P. gelida Bragin, sp. nov., P. voluta Bragin, sp. nov., Kahlerosphaera retunsa Bragin, sp. nov., Capnuchosphaera deweveri Kozur et Mostler, Sarla globosa Bragin, sp. nov., Palaeosaturnalis mocki Kozur et Mostler, Paronaella aquilonia Bragin, sp. nov., Syringocapsa turgida Blome, and Droltus gelidus Bragin, sp. nov.; (4) a Middle Norian assemblage with Sarla globosa Bragin, sp. nov., Sarla sp., Syringocapsa turgida Blome, Canoptum sp., and Laxtorum? sp. The fact that these assemblages include taxa that are recorded more southerly, including paleotropical localities, and support dating based on mollusks, enables the use of these data for Boreal-Tethyan correlation. The greatest similarity to Tethyan associations is observed in the Late Carnian and Early Norian, that is, the periods of the greatest penetration of thermophilic mollusks into this basin. A total of 69 radiolarian species of 3 orders, 18 families, and 29 genera are described; 44 species are newly described; the stratigraphic and geographical ranges of the majority of taxa are improved considerably.  相似文献

Based on light and scanning electron microscopical studies, two new gonad-infecting species of Philometra Costa, 1845, P. draco n. sp. and P. radiata n. sp. (Nematoda: Philometridae), are described from the marine perciform fishes Trachinus draco (Linnaeus) and T. radiatus (Linnaeus) (both Trachinidae), respectively, in the Gulf of Hammamet, off the northeastern coast of Tunisia. Philometra draco n. sp. and P. radiata n. sp. can be separated from other gonad-infecting species of this genus by the structures associated to the gubernaculum (e.g. dorsal protuberance, smooth field separating the dorsolateral longitudinal parts), as well as by the length of the body, spicules and gubernaculum. Philometra radiata n. sp. can be distinguished from P. draco n. sp. in having the dorsal side of the gubernaculum distal end provided with a median longitudinal smooth field demarcated by two dorsolateral lamellate parts. These two new species are the first philometrid species described from fishes of the family Trachinidae.  相似文献

The tribe Formicini (Formicinae) from the Late Eocene Baltic, Bitterfeld, Rovno, and Scandinavian ambers is revised. Ants are recorded for the first time from the Bitterfeld and Scandinavian ambers. Two new genera (Cataglyphoides gen. nov. and Conoformica gen. nov.) and six new species (Cataglyphoides intermedius sp. nov., Conoformica bitterfeldiana sp. nov., Formica kutscheri sp. nov., F. palaeopolonica sp. nov., F. radchenkoi sp. nov., F. zherikhini sp. nov.) are described. A new combination, Cataglyphoides constrictus (Mayr, 1868), comb. nov., is established. A lectotype of Camponotus constrictus Mayr, 1868 and a neotype of Formica phaethusa Wheeler, 1915 are designated. Formica clymene Wheeler, 1915 is recognized as a new synonym of F. phaethusa Wheeler, 1915. An identification key for workers of Formicini species from Late Eocene European ambers is provided.  相似文献

The heteromorph ammonites of the family Bochianitidae from the Lower Cretaceous of the Crimean Mountains are revised. The validity of the genus Janenschites, separated from the genus Bochianites is confirmed. The species Bochianites neocomiensis (d’Orbigny), B. goubechensis Mandov, B. levis sp. nov. and B. crymensis sp. nov. are described from the Berriasian and the species Janenschites oosteri (Sarasin et Schöndelmayer) and J. incisus sp. nov. are described from the Lower Barremian. The family Bochianitidae first appeared at the beginning of the Berriasian in the southern regions (Africa and the Crimea), and spread to the northern regions of western Europe in the Valanginian-Hauterivian.  相似文献

Upper Permian (Murghabian) sponges from the Surmaq Formation exposed in the Hambast Mountains, south of Abadeh, central Iran are described. The sponge fauna of the Surmaq Formation is composed of at least 26 taxa, including 12 species of sphinctozoans, 12 species of inozoans, one operculospongid, and one lithistid species. The following taxa were determined to genus or species level: Sphinctozoa: Family Sebargasiidae: Amblysiphonella hambastensis n. sp., Discosiphonella iranica n. sp., Family Colospongiidae: Colospongia cortexifera Senowbari-Daryan and Rigby, Exaulipora permica (Senowbari-Daryan), Platythalamiella sp. 1, Platythalamiella? sp. 2, Parauvanella minima Senowbari-Daryan, Colospongia? or Neoguadalupia? sp., Family Guadalupiidae: Cystothalamia surmaqensis n. sp., Imbricatocoelia cf. paucipora Rigby, Fan and Zhang, Family Thaumastocoeliidae: Sollasia ostiolata Steinmann, Family Cryptocoeliidae: Stylocoelia circopora Wu. Inozoa: Family Peronidellidae: Preperonidella cf. Preperonidella recta grossa (Wu), Heptatubispongia symmetrica Rigby and Senowbari-Daryan, Hambastella sincassa n. gen., n. sp., Hambastella cumcassa n. sp., Family Maeandrostiidae: Maeandrostia kansasensis Girty, Maeandrostia? dubia n. sp., Surmaqella pustulata n. gen., n. sp., Family Auriculospongiidae: Pseudopalaeoaplysina huayingensis Wang, Qiang and Zhang, Family Disjectoporidae: Disjectopora beipeiensis Fan, Rigby and Zhang, Lichuanopora cf. bancaoensis Fan, Rigby and Zhang, Family Khmeriidae: Imilce newelli Flügel. Lithistida: Family Astylospongiidae: Raanespongia iranica n. sp. Among the sphinctozoans A. hambastensis n. sp. is an extremely abundant species. Among the inozoans the genus Hambastella n. gen., with both species, is the most abundant genus. The genera Disjectopora, Lichuanopora, and Pseudopaleoaplysina, were described as hydrozoans by early workers, but are assigned to the inozoans in this paper. The Upper Permian sponge fauna, as well as the composition of other reef organisms, from the Hambast Mountains in central Iran is different from that of the assemblage in the Lower Permian reefal limestones of Bagh-e Vang from the Shotori Mountians (northeast Iran).  相似文献
