The stonefly genera Dobbertiniopteryx Ansorge and Karanemoura Sinitshenkova are revised. Based on new material from the Middle Jurassic of Daohugou, China, two new species, D. juracapnia sp. nov. and K. manca sp. nov., are described and Karanemoura abrupta Sinitshenkova, 1987 is redescribed. K. desiliens Sinitshenkova, 1987 is excluded from Karanemoura; its position within the family Perlariopseidae remains uncertain. The placement of Dobbertiniopteryx in the modern family Capniidae is confirmed. The perfect state of preservation of the nearly complete adult stonefly remains from China made it possible to improve and extend the diagnoses of the Perlariopseidae and Dobbertiniopteryx. The geological background of the Daohugou deposits is briefly discussed. 相似文献

The extinct family Archisargidae, which was rich in the Mesozoic, has been found in China, Kazakhstan and Mongolia. By now, six genera and 14 species have been found in Inner Mongolia and Liaoning Province of China. In this paper, two new species of the genus Mesosolva Hong, 1983 and a new genus Brevisolva gen. nov., represented by a new species belonging to the Archisargidae, are described from the Middle Jurassic deposits of Daohugou, Inner Mongolia. A key to the species of Mesosolva is given. 相似文献

Hymenopterans Xyelula alexandri Rasnitsyn, sp. nov. (Sepulcidae) and Kotaphialtites frankmortoni Rasnitsyn, gen. et sp. nov. (Ephialtitidae) are described from the Lower or Middle Jurassic Kota Formation, Andhra Pradesh, India. These finds prove a considerable similarity between the Gondwanan and Laurasian hymenopteran faunas during the Jurassic, as well as during the Triassic and Cretaceous. 相似文献

Abstract Two new genera and six new species of Palaeontinidae are named and described: Liaocossus hui gen. et sp. nov., L. beipiaoensis gen. et sp. nov., L. exiguus gen. et sp. nov., L. fengningensis gen. et sp. nov., L. pingquanensis gen. et sp. nov., and Miracossus ingentius gen. et sp. nov., The entire body of these new fossils are perfectly preserved and enable us to fix accurately the body characteristics of primitive palaeontinids. All the specimens were collected from Late Jurassic Yixian Formation of Northern Hebei and Western Liaoning Provinces in China. 相似文献

Based on the study of more than 300 isophlebiid specimens from several Late Mesozoic sites in eastern Transbaikalia (Ukurei, Tergen’, Glushkovo, and Byankino formations), new genera and species are described: Xeta olovica, Dahurium draco, and Sinitsia sophiae. The insect-bearing deposits are dated Late Jurassic according to analysis of their odonatofauna. 相似文献

本文描述了我国冀北和鲁东上侏罗统摇蚊科化石3属、3种,其中,1新属和3新种。冀北大北沟组中不存在Chironomaptera gregaria种化石,以前被鉴定为幽蚊科的这个种实际上应为摇蚊科的1个新种。并对如何区分上侏罗统这两个科成虫化石作了简述。 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

Abstract: A systematic account of highly diverse cyrtocrinid faunules from Upper Jurassic strata of ?tramberk type (Oxfordian–Tithonian) in southern Poland (Polish Carpathians) is presented. Fourteen taxa (Phyllocrinus malbosianus, Ph. stellaris, Ph. sp., Psalidocrinus armatus, Sclerocrinus compressus, S. polonicus sp. nov., Hemicrinus aff. kabanovi, Ancepsicrinus parvus gen. et sp. nov., Tetracrinus baumilleri sp. nov., Eugeniacrinites alexandrowiczi, E. cf. moravicus, E. sp., Eudesicrinus gluchowskii sp. nov. and Hemibrachiocrinus tithonicus sp. nov. are described and illustrated. Representatives of the genus Eudesicrinus, previously recorded only from the Lower Jurassic, are here shown to extend into the uppermost Jurassic. Other cyrtocrinids considered are common in Jurassic/Cretaceous strata across Europe. In the present faunules, isocrinid (Isocrinida), comatulid (Comatulida) and roveacrinid (Roveacrinida sensu Rasmussen, inclusive of Saccocoma) crinoids are associated. 相似文献

A new dicynodont genus and species, Idelesaurus tataricus sp. nov. (Cryptodontidae), from the Semin Ovrag locality (Tatarstan, Tetyushinskii District; Upper Permian, Upper Tatarian Substage, Severodvinian Horizon) is described. The skull patterns of the East European and South African Cryptodontidae and Aulocephalodontidae are compared from the morphofunctional point of view. 相似文献

A new genus and species of pachyosteomorph arthrodire, Omalosteus krutoensis gen. et sp. nov. from shallow-water marine deposits of the Evlanovo Regional Stage (Upper Frasnian, Upper Devonian) of the Central Devonian Field is described. It is tentatively referred to the family Trematosteidae Gross, 1932, which was earlier believed to be endemic to central Europe. The new genus is characterized by a rounded, dorsoventrally compressed cross section of the pectoral region and smooth head shield and postcranial membrane bones. The centrale is elongated, forming a narrow lateral lobe. The praeorbitale, postorbitale, and centrale come in contact in the center of the orbital region. The mediodorsale is wide, its carinal process projects considerably posteriorly. The anterior margin of the anterior ventrolaterale lacks articular facets for the interlaterale. 相似文献

The new scleractinian coral genusHexasmiliopsis is described on the basis of material from the Early Aptian (Early Cretaceous) of Murcia (Spain). The new genus of the Heterocoeniidae
family is characterised by its solitary growth form, a very strong main septum and the presence of apophysal septa. It is
closely related to the generaHexasmilia (phaceloid growth form),Rodinosmilia andTiarasmilia (both without main septum). The genus is monospecific and represents only the type species,Hexasmiliopsis saldanai.
