The Late Tremadoc storm-dominated shoreface to inner platform deposits exposed west of the Purmamarca village (Coquena Formation) contain a considerably more diverse brachiopod fauna than previously reported. Coquinite horizons from the lower heterolitic succession have yielded monospecific associations of Nanorthis purmamarcaensis nov. sp. (formerly assigned to N. christianiae KJERULF), which is also reported from the Late Tremadoc rocks of the Cerro San Bernardo area. The fine-grained Upper Member of the Coquena Formation contains a more diverse fauna composed by Nanorthis brachymyaria nov. sp., Astraborthis quebradensis nov. sp. and the new plectorthid genus Lipanorthis (type species L. andinus nov. sp.). A different species of Lipanorthis (L. santalaurae nov. sp.) from the Mid Tremadoc Floresta Formation of the Sierra de Mojotoro is also described.  相似文献

A revision of previously known material and analysis of new records of Miocene baleen whales from the Sarmatian of Adygea (city of Maikop, Blinovo Formation) resulted in the establishment of a new genus, Kurdalagonus with three species: K. mchedlidzei sp. nov. (Middle Sarmatian, Nagiezh-Uashkh locality), K. adygeicus sp. nov. (Upper Sarmatian, Hydroelectric power station locality), and K. maicopicus (Spasskii, 1951) (=Cetotherium maicopicum Spasskii, 1951; Middle Sarmatian, Hydroelectric power station locality).  相似文献

Nymphs of fossil grylloblattid insects are revised. Newly described taxa are Lemmatonympha gracilissima gen. et sp. nov. and Kaltanympha vorcutensis sp. nov. from the Verkhne-Syr’yaginsk locality (Ufimian, Lek-Vorkuta Formation in the Vorkuta Coal Basin), genera Sylvalitoralis gen. nov. and Tshebardanympha gen. nov. from the Tshekarda locality (Kungurian, Koshelevka Formation, Middle Urals), Tataronymphakamensis gen. et sp. nov. from the Tikhie Gory locality (Lower Kazanian, linguloid beds of the Baitugan Formation, Tatarstan), and Kaltanympha ornata sp. nov. from the Kerbo locality (Upper Tatarian, lower part of the Degali Formation, Evenki Autonomous Region). Liomopterites (?) gracilis Sharov, 1961 from Lower Kazanian deposits of the Kuznetsk Formation in the Kuznetsk Basin is transferred to the genus Kaltanympha Sharov, 1961; Permonympha arcuata Sharov, 1957 from the same locality is synonymized under Permonympha gracile Sharov, 1957; the nymph described from the Karatau locality (Upper Jurassic, Karabastau Formation in southern Kazakhstan) as Blattogryllus karatavicus Rasnitsyn, 1976 is excluded from grylloblattids. Keys to extinct grylloblattid nymphs are provided.  相似文献

Bryozoans from the Mitikha Formation (Lower Famennian, Upper Devonian) in the Kuznetsk depression are described for the first time. This bryozoan assemblage comprises both the well-known species Leioclema numerosum Moroz., L. ramosum Nekh., and Nicklesopora graciosa Troiz. and new taxa: L. kusmense sp. nov. and Megacanthopora glubokaensis sp. nov. The bryozoan assemblage contains some species common with the Famennian bryozoan assemblage of Kazakhstan.  相似文献

Plant macrofossil remains from the Lyamtsa and Arkhangelsk beds of the Ust’-Pinega Formation (Vendian) are reported for the first time. Three new taxa of vendotaenid algae showing cellular parenchymatous morphology are described: Archyfasma lamellata sp. nov., Favosiphycus wukii gen. et sp. nov., and Gandvikia caudata gen. et sp. nov. Phytostratigraphic characteristics allow the author to correlate the deposits under study with the base of the Mogilev Formation (Vendian of Podolia). A distinctive Lower Redkino vendotaenid flora is described for the first time. It is shown to precede the Upper Redkino Eoholynialen flora.  相似文献

One new genus and five new species of dragonflies (Odonata) are described and figured from the Yixian Formation of northeastern China, viz. two gomphaeschnids Sinojoria magna nov. sp. and S. cancellosa nov. sp., plus three progobiaeshnids Mongoliaeshna hadrens nov. sp., M. exiguusens nov. sp., and Decoraeshna preciosus nov. gen., nov. sp. These new discoveries confirm the apparently sudden great diversification in China of the clade Aeshnoptera during the Middle-Upper Jurassic, together with the Upper Mesozoic to modern lineages of dragonflies. At the same time, some ‘ancient’ groups of Odonata became extinct.  相似文献

The acritarchs and prasinophyte algae from the Upper Bringewood, Lower Leintwardine, Upper Leintwardine and Lower Whitcliffe formations of the Ludlow type area and surrounding regions are described. The following new taxa are proposed: Cymatiosphaera pumila sp. nov., Melikeriopalla pustula sp. nov., Cheleutochroa beechenbankensis sp. nov., Cymbosphaeridium molyneuxii sp. nov., Flammulasphaera bella gen. et sp. nov., Percultisphaera incompta sp. nov., Salopidium aldridgei sp. nov. and Umbellasphaeridium? wicanderi sp. nov. A holotype is defined for Lophosphaeridium galeatum Hill and a further 34 new taxa are described under open nomenclature. Two biozones, identified by the first appearance of the zone taxon, are defined in the Sunnyhill section, Ludlow [Global Stratotype Section and Point (GSSP) for the base of the Ludfordian Stage, Ludlow Series]. The base of the Leoniella vilis Biozone is identified at 4.52m below the top of the Upper Bringewood Formation at Beechenbank, Aymestrey. The base of the Triangulina sanpetrensis Biozone is identified at 15.49m above the base of the Lower Leintwardine Formation and Ludfordian Stage at the Sunnyhill section. These biozones allow correlation with sections in north–west Spain, Podolia and Gotland. The possibility of using Visbysphaera whitcliffense and U.? wicanderi as biozonal indicators is suggested.  相似文献

The Ogonerian association of Early Permian ammonoids from the Upper part of the Munugudzhakian Formation (upper part of the Ogonerian Horizon) contains Uraloceras omolonense Bogoslovskaya et Boiko, U. kolymense Bogoslovskaya et Boiko, Neoshumardites munugudzhensis sp. nov., N.? nassichuki sp. nov., and Bulunites gracilis sp. nov. These taxa suggest the Sakmarian-Artinskian boundary beds examined are geochronologically older than the level with Neoshumardites triceps Ruzhencev in the South Ural Mountains.  相似文献

Two new dinosaurs, Kulindapteryx ukureica gen. et sp. nov. (Jeholosauridae) and Daurosaurus olovus gen. et sp. nov. (Hypsilophodontidae) from the Ukureisk Formation (?Tithonian, Upper Jurassic) of the Kulinda locality in Transbaikalia (Russia) are described and assigned to Ornithopoda (Ornithischia). The origin and homology of the so-called obturator process of the ischium of Ornithopoda and Theropoda are discussed. The families Jeholosauridae and Hypsilophodontidae as well as Lesothosauridae are considered to belong to the infraorder Hypsilophodontia (Ornithopoda, Ornithischia). It is shown that hypsilophodontians had skin scales divided into bristles.  相似文献

A new horned dinosaur, Gobiceratops minutus gen. et sp. nov. (Bagaceratopidae, Neoceratopsia), from the Upper Cretaceous Baruungoyot Formation of the Khermin Tsav locality (southern Mongolia) is described based on a 3.5-cm-long skull. The nasal included in the orbital border suggests relationship between the new taxon and Bagaceratops rozdestvenskyi. It is proposed that, unlike other neoceratopsian families, the family Bagaceratopidae is of Paleoasiatic origin.  相似文献

New beetles are described from the Middle Permian (Upper Capitanian) locality Yinping (Anhui Province, China): Linicupes yinpinensis gen. et sp. nov. (Permocupedidae), Taldycupes pingi sp. nov. (Taldycupedidae), Archosyne permiana gen. et sp. nov., Chaocoleus limnebius gen. et sp. nov. (Ademosynidae) and Asiocoleopsis hongi sp. nov. (Asiocoleidae); the type material of Dikerocoleus divisus Lin, 1982 from the same type locality is redescribed. Comparison with beetles from the Permian of European Russia shows that Yinping beetles are similar to Late Severodvinian beetles rather than to Early Severodvinian and Urzhumian ones.  相似文献

A new species, Laricioxylon erkovetskiense sp. nov. (Pinaceae) identified on the basis of anatomical features of fossil wood from the Sazanka Formation (upper Middle Miocene–Upper Miocene) of the Erkovetskii Brown Coal Field (Amur Region) is described. The new species shares some characters with the extant larches Larix cajanderi and L. olgensis.  相似文献

A low-diversity cockroach assemblage from the Upper Jurassic of the Houtiyn-Hotgor locality in Mongolia is described, comprising Solemnia alexandri gen. et sp. nov. (Caloblattinidae), Blattula choutinensis sp. nov. (Blattulidae) and a presumed Triassic relict Irreblatta relicta gen. et sp. nov. (incertae familiae). The carnivorous Raphidiomimidae supposedly originated directly from the Caloblattinidae.  相似文献
