New representatives of the family Melagathiceratidae (Ammonoidea) from the Lower Triassic of South Primorye

A new ammonoid genus, Ussurijuvenites (Melagathiceratidae), is described from the early Olenekian of South Primorye, represented by two new species (U. popovi sp. nov. and U. artyomensis sp. nov.); data on the inner shell structure of melagathiceratid ammonoids (based on U. artyomensis sp. nov.) are presented for the first time.     

Evolution of the Permian family Spirolegoceratidae (Goniatitida,Ammonoidea)

The evolution of the Permian ammonoid family Spirolegoceratidae is discussed and a new phylogenetic reconstruction is proposed based on new data. Two subfamilies are recognized within the family Spirolegoceratidae: Spirolegoceratinae Nassichuk and Sverdrupitinae subfam. nov. A new genus, Archboldiceras, is proposed to accommodate the Australian species Uraloceras lobulatum and U. whitehousei. Species of the genus Sverdrupites Nassichuk, 1970 are described based on new material from the Volga-Urals Region. The new species S. bogoslovskayae from the Gerkinskaya Formation of Novaya Zemlya previously identified by M.F. Bogoslovskaya as S. amundseni is described.     

A new species of trilobites from Sakmarian Reefs of Bashkortostan

The new trilobite species Cummingella (Cummingella) boikoi sp. nov. is described from the Lower Permian reef facies (Sakmarian Stage) of Bashkiria (Bashkortostan). The new findings extend the known range of the Permian genus Cummingella Reed, 1942 and provide the first record of trilobites in Sakmarian deposits of Bashkiria.     

New ammonoid taxa from the Lower Cretaceous Giumal Formation of the Tethyan Himalaya (Northern India)

Knowledge of the Early Cretaceous ammonoids of the NW‐Himalayas was poor until recent discoveries. Intense sampling from the Giumal Formation exposed near the village of Chikkim (Spiti Valley, Himachal Pradesh, India) led to the recognition of a new Early Cretaceous ammonoid fauna. The succession consists of arenitic sandstone interbedded with shale that was deposited by turbidity currents on an unstable shelf in the Early Cretaceous. Ammonoids have been obtained only from sandstone beds in the lower one‐third and close to the top of the c. 350‐m‐thick section. Eight new ammonoid taxa (1 genus and 7 species) are described: Sinzovia franki sp. nov. (rare), Giumaliceras giumaliense gen. et sp. nov. (abundant), Giumaliceras bhargavai gen. et sp. nov. (rare), Neocomites (Eristavites) platycostatiformis sp. nov. (rare), Cleoniceras oberhauseri sp. nov. (abundant), Australiceras himalayense sp. nov. (rare) and Deshayesites fuchsi sp. nov. (rare). Sinzovia and Deshayesites are reported for the first time from the Tethyan Himalaya. According to the biostratigraphic relevance of some ammonoid taxa described here, the age of the Giumal Formation can be constrained from Berriasian (Giumaliceras assemblage) to Aptian (Cleoniceras assemblage). The discovery of the new fauna substantiates the significance of the Giumal Formation around Chikkim and facilitates comparison with faunal assemblages from other regions in the Tethys Ocean and beyond.     

A new ammonoid fauna from the Carnian (Upper Triassic) Kasimlar Formation of the Taurus Mountains (Anatolia,Turkey)

We describe a new ammonoid fauna from the Taurus Mountains of southern Turkey. The Carnian ammonoid fauna from A?a?iyaylabel is presented for the first time. Ammonoids were obtained from limestone to marl beds of an approximately 35‐m‐thick section, which presents the rare opportunity to investigate ammonoid faunas across the Lower–Upper Carnian boundary. Intense sampling near the village of A?a?iyaylabel led to the recognition of a new Lower Carnian (Julian 2) to Upper Carnian (Tuvalian 1) ammonoid fauna from the Kasimlar Formation. The genus Kasimlarceltites gen. nov. is reported for the first time from the Taurus Mountains, which represents the main faunal element and occurs as huge mass occurrence (n ? 1 million). Kasimlarceltites krystyni gen. et sp. nov., Klipsteinia disciformis sp. nov. and Anasirenites crassicrenulatus sp. nov. occur within the Lower Carnian Carbonate member (Units A–B) of the Kasimlar Formation from the Taurus Platform Units. Ammonoids described from the marls of the Tuvalian Marlstone member were deposited during a major, Tethyan‐wide climate crisis – the so‐called Carnian crisis – characterized by a demise of carbonate platforms. Based on the biostratigraphic relevance of certain ammonoid taxa described herein, the age of the analysed parts of the Kasimlar Formation is Julian 2 to Tuvalian 1. The discovery of the new ammonoid assemblages from A?a?iyaylabel substantiates the significance of Upper Triassic faunas within the Taurus Mountains and facilitates the correlation with faunal assemblages from other regions in the Tethyan Realm. The ammonoid fauna and facies indicate a general deepening from open‐platform margins, over deeper shelf settings down to an open marine‐influenced basinal environment. The tentative habitat for Kasimlarceltites gen. nov. is a shallow platform environment to upper mid‐ramp.     

Permian ammonoids of the Kolyma-Omolon Region: Ogonerian association

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.     

The latest record of mayflies of the family protereismatidae sellards (Ephemerida = Ephemeroptera) and a new species of the family misthodotidae in the Upper Permian of Europe

A new mayfly genus and species, Alexandrinia gigantea gen. et sp. nov., is described in the family Protereismatidae from the Upper Permian locality of Isady (Severodvinian Stage, Poldarsa Formation). Protereisma directum Carpenter, 1979, known from the Early Permian of Oklahoma, United States, is transferred to this new genus. Another new species, Misthodotes tshernovae sp. nov., is described in the family Misthodotidae.     

New species of sap beetles (Coleoptera: Nitidulidae: Nitidulini) from the Baltic and Bitterfeld ambers

A new genus, Microsoronia, gen. nov., and new species of this genus, M. hoffeinsorum, sp. nov. from the Bitterfeld amber and M. kerneggeri sp. nov., M. nigerrima sp. nov., and M. interfax, sp. nov. from the Baltic amber, are described. The earliest known member of the genus Phenolia, P. (Lasiodites) angustitibialis, sp. nov., is described from the Baltic amber. The systematic position of these two genera, their possible evolution, as well as the possible ecology and bionomics of their members are discussed. It is shown that “Phenolia” incapax Scudder, 1890 should be included in the family Peltidae, rather than Nitidulidae.     

New stoneflies (Insecta: Perlida = Plecoptera) from Eocene Rovno amber,Ukraine

A new genus, Rovnocapnia gen. nov., with new species R. atra sp. nov. and R. ambita sp. nov., from the family Capniidae, and a new genus and species Palaeoleuctra acuta gen. sp. nov., from the family Leuctridae, of the suborder Nemourina (Euholognatha), are described from Late Eocene Rovno amber. Familial assignment of one additional specimen (suborder Perlina, infraorder Perlomorpha (Systelognatha)), represented by a nymphal skin, is obscure due to its incomplete preservation.     

A new Permian ammonoid fauna of the Kobylka River (North Urals)

A new ammonoid fauna from the Artinskian-Kungurian boundary beds is described from the Kobylka River basin (North Urals). Two new species, Sakmarites tardus sp. nov. and Paragastrioceras kobylkense sp. nov., are described.     

Ammonites of Tethyan origin in the Ryazanian stage of the Russian platform: Genus <Emphasis Type="Italic">Riasanella</Emphasis> gen. nov.

A new ammonite genus Riasanella is described from the Ryazanian Stage of the Russian Platform (type species R. rausingi sp. nov.). The new species R. plana sp. nov., R. olorizi sp. nov., and R. riasanitoides sp. nov. are described. These species come from the lower, strongly condensed beds of the Riasanites rjasanensis Zone of the Moscow Region. The upper subzone of this zone in the Ryazan Region contains specimens of Riasanella, identified in open nomenclature. The new genus is assigned to the family Himalayitidae; one of its species is a possible ancestor of Riasanites Spath.     

New species of Dzhulfian (Late Permian) ammonoids from the Hambast Formation of Central Iran

New ammonoid species of the genus Araxoceras (A. abarquense sp. nov. and A. iranense sp. nov.) are described from the Early Dzhulfian (Early Wuchiapingian) beds of the Hambast Formation of Central Iran (Abade). The data on the distribution of Paraceltites (Paraceltites sp.) and Vedioceras (V. umbonovarum Ruzhencev), for the first time discovered in the Dzhulfian beds of Abade, and of Eoaraxoceras are provided. The correlation of the Late Permian assemblages of ammonoids of Iran and Transcaucasia is amended.     

New stoneflies (Insecta: Perlida = Plecoptera) from the late Mesozoic locality Khasurty,Transbaikalia

From the Lower Cretaceous locality Khasurty, western Transbaikalia, a new genus and species, Rasnitsyrina culonga, gen. et sp. nov. are described in the family Perlariopseidae. R. desiliens (Sinitshenkova, 1987), originally described in the genus Karanemoura Sinitshenkova, 1987, is transferred to the new genus. Two new species belonging to recent families are described: Dimoula khasurtensis sp. nov. (Nemouridae) and Jurataenionema rohdendorfi sp. nov. (Taeniopterygidae). All new species are described from fossils of adults.     

New fossil insects (Diaphanopterodea: Martynoviidae) from the Lower Permian of the Boskovice Basin, southern Moravia

Two new genera and new species assigned to the family Martynoviidae (Diaphanopterodea), Boskovicia celtai nov. gen., nov. sp. and Moravoptera hladilovae nov. gen., nov. sp. are described and illustrated from the Lower Permian (Artinskian/Sakmarian) locality of Obora, southern Moravia (Czech Republic). Discovery of the species Martynovia insignis Tillyard, originally described from the Lower Permian of Kansas (USA), supports close relationship of both faunas across Euramerica.     

Biostratigraphy and important biotic events in the Western Verkhoyansk Region around the Sakmarian–Artinskian boundary

A diverse marine invertebrate fauna was found in the Echij Formation (Sakmarian–Artinskian) at the Arkachan, Chelge, and Nizhnyaya Dielendzha sections, all Western Verkhoyansk Region, North-East of Russia. The biostratigraphic sequence of ammonoid, brachiopod, bivalve, and foraminiferal assemblages in the Echij Formation of the Western Verkhoyansk Region is studied. Five ammonoids units are identified in the Echian Regional Stage (“Horizon”): Uraloceras subsimense, Uraloceras omolonense, Neoshumardites triceps hyperboreus, Eotumaroceras endybalense, and Eotumaroceras subyakutorum beds. The first two divisions contain ammonoids of the Arkachanian association, and the last three contain the Endybalian association. The boundary between the Sakmarian and Artinskian stages is established at the base of Neoshumardites triceps hyperboreus beds. In the Sakmarian interval of the Echij Regional Stage of the Verkhoyansk Region, a brachiopod biostratigraphic sequence similar to that of the Kolyma–Omolon Region is observed: Jakutoproductus insignis, Jakutoproductus terechovi, and Jakutoproductus rugosus zones. In the lower part of the Artinskian stage, Uraloproductus stuckenbergianus beds are identified, which are characterized by a rich brachiopod assemblage (Peregoedov et al., 2009), not typical for Verkhoyansk Region. The bivalves, identified in the Lower Echij Subformation, presumably belong to the Merismopteria permiana, Cypricardinia eopermica, and Cypricardinia borealica zones of the Ogonerian Horizon of the Kolyma–Omolon Region. Bivalves of the Middle and Upper subformations are characteristic of the Edmondia gigantea and Aphanaia lima zones of the Koargychanian Regional Stage (“Horizon”). The foraminifera complex identified in the Echij Formation is compared with the complex of the lower part of the Sandy Foraminifera horizon of the northeast of the Siberian platform, to which the Tustakh Formation belongs. The beginning of the wide distribution of the Early Permian foraminifera in the Western Verkhoyansk Region was recorded at the base of the Artinskian. The Sakmarian–Artinskian boundary interval in the Verkhoyansk Region is characterized by three significant biotic events: the replacement of the brachiopod Jakutoproductus by Inoceramus-like bivalves, the first appearance of the Endybalian ammonoid association, and biotic invasions from the Uralian and North American regions. An important factor of the Late Sakmarian–Early Artinskian events was a large sea level rise (the Echian transgression), which significantly changed the environmental conditions for East Siberian marine invertebrates, and contributed to the spread of new faunas.     

<Emphasis Type="Italic">Orientosirenites</Emphasis>, a New Ammonoid Genus (Sirenitidae; Ammonoidea) from the Upper Carnian of the Boreal Realm

The ammonoid family Sirenitidae from the Upper Carnian yakutensis Zone of northern Middle Siberia and Northeastern Asia is revised. A new genus Orientosirenites gen. nov. with the type species O. bytschkovi sp. nov. is established based on the study of the main morphological characters of the shell. The new genus and the species O. bytschkovi are described and the species O. yakutensis (Kiparisova) is redescribed. The new data allow the taxonomic composition and the distribution of the Carnian ammonoids of the Boreal Realm to be updated.     

Review of grylloblattid insects (Insecta: Grylloblattida) from the Solikamsk deposits of the Perm Region

The Solikamsk faunas of the Vorkuta series of the Pechora Basin and the Solikamsk Formation of the Perm Region of Russia are reviewed. New taxa are described from Tyul’kino locality (Solikamsk District): Artinska ufimica sp. nov., Sylvaprisca tyulkinensis sp. nov., Ufimoprisca gen. nov. (the type species Sylvaprisca alba Aristov, 2005), U. mica sp. nov., U. kamensis sp. nov. (family Lemmatophoridae), Sylvaella ovalis sp. nov. (family Liomopteridae), Ivakhosara prima sp. nov., and Megakhosarella prisca sp. nov. (family Megakhosaridae). Additionally, Uralioma sp. is described from Shchugor locality (Cherdyn’ District). Two species, Paraprisca solikamskensis Aristov, 2009 (family Lemmatophoridae) from Tyul’kino and Kolvidelia curta G. Zalessky, 1950 (family Ideliidae) from Pokcha locality (Cherdyn’ District)), are redescribed.     

New members of the family flemingitidae (Ammonoidea) from the Lower Triassic of South Primorye

New species of flemingitid ammonoids (Flemingites trikamnyaensis sp. nov., F. alexanderi sp. nov., Rohillites? ambiguus sp. nov., Euflemingites extremus sp. nov.) from the Olenekian of South Primorye are described. The shell interior of flemingitid ammonoids is studied for the first time based on Ussuriflemingites abrekensis Shigeta et Zakharov. The usefulness of the early-ontogenetic morphological test (EMT) for substantiation of ammonoid taxa at the family level is discussed.     

The first discovery of apartidae (ammonoidea) in the Carnian of northeastern Asia

A new genus Siberioklipsteinia (with the type species S. dagysi sp. nov.) and a new species Arctoarpadites nelgesensis are described from the Carnian of the Kharaulakh Range and Yana Upland (eastern Yakutia). The new data allow refinement of the taxonomy of Carnian ammonoids of northeastern Asia and emendation of some details of their geographical differentiation. The new ammonoid taxa belong to the family Arpaditidae, which was not previously recorded from the eastern Boreal Realm.
