A dorsal vertebra referred to as Azhdarchidae indet. from the Rybushka Formation (Upper Cretaceous, Lower Campanian) of the Beloe Ozero locality in the Saratov Region is described. Its vertebral centrum has a hypapophysis and, at the base of the neural arch, there is a large pneumatic foramen. The vertebra possibly belongs to Volgadraco bogolubovi Averianov, Arkhangelskii et Pervushov, 2008, described from the Rybushka Formation of the Shirokii Karamysh 2 locality in the Saratov Region.  相似文献

A new azhdarchid genus and species, Volgadraco bogolubovi gen. et sp. nov., is described based on an anterior fragment of the mandibular symphysis (mandibular beak) and some postcranial elements from the Rybushka Formation (Upper Cretaceous, Lower Campanian) of the Shirokii Karamysh 2 locality, Saratov Region. The new taxon is intermediate in size and vascularization of the mandibular beak between medium-sized Turonian-Santonian azhdarchids (Azhdarcho, Bakonydraco) and the giant Maastrichtian azhdarchid Quetzalcoatlus.  相似文献

The taxonomic position of the microproblematics previously considered to be Foraminifera or Calcisphaerulidae is established. The first record from Russia of calcareous cysts of Dinoflagellata is presented. The microfossils originate from the Maastrichtian siliceous clay of the Volga River Region.  相似文献

Results of modern carpological studies of the Ples section in the Upper Volga Region are discussed. The section includes sediments of the Mikulino (Eemian) Interglacial and Early Valdai (Early Weichselian) Glacial. Particular attention is given to Early Valdai carpological assemblages. The analysis of their composition and comparison with palynological data from the locality and carpological data from western regions of the East European Plain allows one to assign the assemblages under study to two relatively warm episodes of interstade type. For the first time, the carpological characteristics of two warm episodes are given for this territory.  相似文献

A pterosaur vertebral column consisting of the last cervical vertebra, the first five dorsals fused to a notarium, and the following four dorsal vertebrae, is figured and described from the Aptian Santana Formation of the Chapada do Araripe in northeastern Brazil. The specimen is tentatively referred toSantanadactylus brasilensis de Buisonjé. It is the best preserved and most complete pterosaurian notarium known. Its functional significance is discussed.  相似文献

The premaxilla of a mosasauroid lizard from the Lysaya Gora 3 locality in Saratov (Upper Cretaceous, Cenomanian) is described. To date, the oldest known mosasaur remains have been dated Turonian. The premaxilla is most similar in morphology to that of Russellosaurus from the Turonian of the United States; however, the absence of sufficient diagnostic characters only allows its attribution to Mosasauridae indet.  相似文献

Helicomyces geniculatus sp. nov. from decaying wood submerged in a freshwater stream at Juchi Town of Alishan area, Chiayi County, Taiwan, is described and illustrated. It differs from other Helicomyces species in having geniculate conidiophores arising from repent hyphae and also borne on erect setae. Abundant stalked sclerotia were also found in this species. Helicomyces torquatus is described in this paper as a new record for Taiwan, with new observation. The phylogenetic relationship of H. geniculatus, H. torquatus, and related taxa were sought by comparing the sequences of their ITS barcode of the nuc rDNA. A synopsis of the 13 accepted Helicomyces species is given.  相似文献

A new genus of ginkgoalean woody branch, Pecínovicladus kvaceki gen. et sp. nov., is described from the Upper Cretaceous (mid to late Cenomanian) Peruc-Korycany Formation at Pecínov Quarry, near Prague, Czech Republic. Eighteen branch specimens, anatomically preserved as charcoal, the product of wildfire, occur as allochthonous assemblages in intertidal facies and as parauthochthonous assemblages in supratidal salt marsh facies. Primary branches range from 7–13 mm in diameter, and are composed of a central, parenchymatous pith, a medial pycnoxylic xylem layer, and an outer periderm layer. Closely spaced, helically arranged leaf bases and rare secondary branch scars characterize the exterior. The branches are confidently referred to the Ginkgoales on the basis of a variety of diagnostic xylem features, most notably the presence of inflated axial parenchyma containing moulds of crystals, and by the precise anatomical correspondence of the leaf bases to those of detached, but facies-associated Nehvizdya obtusa leaves of known ginkgoalean affinity. The newly described ginkgoalean, together with cheirolepidiaceous conifers, formed fire-prone vegetation in halophytic salt marsh environments under a seasonal, subtropical climate.  相似文献

Ostracode faunas have been identified for the firsttime in Early marine Cenomanian sediments of the Ajlun Group (Jordan) outcropping East of the Jordan Rift Valley. The faunal assemblages contain 14 genera and 17 species. Sediments indicate the internal part of a carbonate platform. The Ostracodes are closely related to those of neighbouring regions; accordingly, in the Tethyan context, Jordan belongs to the North Africa — Middle East bioprovince.  相似文献

Orbilia Fr. and Hyalorbilia Baral & G Marson are the only genera currently accepted in the family Orbiliaceae which was established by Nannfeldt (Baral, 1994; Kirk et al., 2001). Hyalorbilia was erected by Baral and Marson (2001) based on unstalked asci arising from crosiers, with hemispherical apices without wall thickenings, some bipolar-symmetrical globose inclusion bodies in ascospores (living state),  相似文献
