Discovery of the genus Iasvia Zalessky, 1934 in the Upper Permian of France (Lodève basin) (Orthoptera, Ensifera, Oedischiidae)

New material attributed to the species Iasvia reticulata ZALESSKY, 1934 and to a new species in this genus is described from the Salagou Formation (Saxonian Group, Lodève basin). Preamble to the taxonomic section, the wing venation pattern of Orthoptera is discussed. The numerous described specimens yield decisive information about variability of wing venation within the genus, previously based on a single specimen from the Russian Permian. I. reticulata is the first species from the Lodève basin that is already known from another site. The biostratigraphic implications are discussed.     

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.     

Lodetiella magnifica nov. gen. and nov. sp. (Insecta: Palaeodictyoptera; Permian), an extreme situation in wing morphology of palaeopterous insects

Based on published data and review of Mecynoptera splendida Handlirsch, 1904, a wing venation ground plan applicable to most taxa of the Palaeozoic superorder Palaeodictyopteroidea is proposed, where each major vein system has a simple anterior sector, and, primitively, a dichotomously branched posterior sector. Lodetiella magnifica nov. gen. and sp. is described, based on an isolated hind wing from the Salagou Formation (Middle to Late Permian; Hérault, France). The venation of Lodetiella magnifica conforms to the predicted ground plan, but differs by its simple posterior cubitus sector. This character is diagnostic of the family Calvertiellidae (Palaeodictyoptera), whose diagnosis is updated. Wing movement in flight is inferred from the peculiar wing vein organization of Lodetiella magnifica. Some ecological preferences might explain the relative rarity of calvertiellids in the fossil record.     

Discovery of the genus Crinoedischia in the Middle Permian of France (Insecta: Orthoptera)

New orthopteran Crinoedischia lapeyriei sp. nov. is described and illustrated from the Middle Permian (Guadalupian) of Lodève Basin in southern France. The new species is separated from the Lower Permian (Artinskian) Crinoedischia species by differences in wing venation pattern such as long ScP with anterior branches, RA with prominent distal branches, and MA ending with three branches. The significance and parallels of entomofaunas between Salagou and Wellington formations (Lodève, Elmo, Midco) are briefly discussed.     

New Grylloblattids of the family Megakhosaridae (Insecta: Grylloblattida) from the Permian of Russia

New Megakhosaridae (Insecta: Grylloblattida) are described from the Permian of Russia: Ivakhosara pectinimedia gen. et sp. nov., Megakhosarina intricata sp. nov. and M. minuscula sp. nov. from the Lower Kazanian of Soyana (Arkhangelsk Region), M. magna sp. nov. from the Urzhumian of Chepanikha (Udmurtia), Kargalokhosara terraefossa gen. et sp. nov. from the Urzhumian of Kargala (Orenburg Region), and Alekhosara reticulata gen. et sp. nov. from the Severodvinian of Novo-Aleksandrovka (Orenburg Region).     

New grylloblattids of the family Lemmatophoridae (Insecta: Grylloblattida) from the Permian of Russia

New grylloblattids of the family Lemmatophoridae (Insecta: Grylloblattida), Artinska sojanensis sp. nov., Sylvaprisca colorata sp. nov., and Uraloprisca lisca gen. et sp. nov., from the Soyana locality (Lower Kazanian, Arkhangelsk Region) and Paraprisca solikamskensis sp. nov. from the Tyul’kino locality (Ufimian, Perm Region) are described. Two species are transferred from the genus Paraprisca to Uraloprisca gen. nov.: Uraloprisca uralica (G. Zalessky, 1952), comb. nov. and Uraloprisca causaria (Novokshonov, 2000), comb. nov. (both from the Kungurian of the Perm Region). The evolution of the family is discussed.     

New insects (Insecta: Mecoptera,Grylloblattida) from the Middle Permian Chepanikha locality,Udmurtia

New scorpionflies, Asiachorista europaea sp. nov. and Petromantis udmurtica sp. nov. (Mecoptera: Permochoristidae), and new grylloblattids, Tshepanichoptera lacera gen. et sp. nov. (Grylloblattida: Aliculidae) and Miralioma urzhumica sp. nov. (Liomopteridae), are described from the Urzhumian of Udmurtia (Chepanikha locality). Liomopterites novissimus Aristov, 2004 (Liomopteridae) is redescribed.     

New and poorly known Cenozoic clown beetle compressions from France (Insecta: Coleoptera: Histeridae)

Summary

Two French fossil Histeridae are described or revised, viz. Hister cerestensis n. sp. from the Oligocene of Céreste (Lubéron) and Plegaderus pitoni (Theobald, 1935), n. comb. from the Pliocene of Chambon Lake (Puy-de-Dôme). Morphometric data are used to compare fossil and extant taxa, with multivariate statistics. A list of the fossil Histeridae is given.     

La migration de la plate-forme urgonienne entre le Jura plissé et les Chaînes subalpines septentrionales (France, Suisse)

The stratigraphic study of the Urgonian carbonate platform presented here was carried out on a directed transversal NW-SE and passing by Geneva. This transversal extends on 100 km length; it lies between the face of the “folded Jura” (Champagnole, the Jura) and the septentrional subalpine chains (Aravis, Haute-Savoie). Essentially based on the biostratigraphy (ammonites, orbitolinids, echinids) and on sequence stratigraphy, this study illustrates the progradation of the Urgonian platform from the “folded Jura” (top of the Lower Hauterivian) to the Aravais chain (lowermost Barremian).     

A new family of the order Grylloblattida (Insecta) from the Middle Permian of Russia

A new family, Ivapteridae fam. nov. (Insecta; Grylloblattida), is described from the Middle Permian locality of Soyana (Arkhangelsk Region; Kazanian Stage). It is most similar to Sojanoraphidiidae O. Martynova, 1952, differing from it in the subcostal field being traversed in the basal half of the wing by long, curved, and strongly oblique crossveins that form a double row of cells, the base of CuA being free, and CuA₁ thin compared to CuA₂. The new family is represented by a single species, Ivaptera sharovi, gen. et sp. nov. An overview of the modern system of the order Grylloblattida is included.     

The first agetopanorpine mecopteroid insect from Middle Permian of China (Insecta: Mecoptera: Permochoristidae)

Sinoagetopanorpa permiana n. gen., n. sp., first Chinese Permian Agetopanorpinae, is described and compared to the other genera of this group.     

New latest Permian foraminifers from Laren (Guangxi Province, South China): Palaeobiogeographic implications

Microfacies analyses performed on the latest Permian Wujiaping Formation at Laren (Guangxi Province, South China) show that the bioclastic-rich limestones of Late Permian age contain a rich and well-diversified foraminiferal fauna. This fauna is here revised in order to be compared with time-equivalent levels of southern Iran and southern Turkey. Some new and unexpected phylogenetic trends are highlighted among the biseriamminoids. The new or poorly known genera Retroseptellina, Septoglobivalvulina, Paraglobivalvulinoides, Dagmarita?, Bidagmarita nov. gen., Louisettita, Paradagmaritopsis nov. gen. and Paradagmarita? are concerned. Nevertheless, these newly appeared biseriamminoids are subordinate to abundant Tetrataxis and Climacammina, ultimate survivors of the families Palaeotextulariidae and Tetrataxidae, appeared as old as the Early Carboniferous (“Mississippian”). Algae, miliolids, and nodosarioids are poorly represented. Two genera and four species are here newly described: Globivalvulina curiosa nov. sp., Louisettita ultima nov. sp., Bidagmarita nov. gen., Bidagmarita sinica nov. gen. nov. sp., Paradagmaritopsis nov. gen., Paradagmaritopsis kobayashii nov. gen. nov. sp. The palaeogeographic distribution of these foraminifers is interpreted to be typically of Neo-Tethyan regions, ranging from southern Turkey (Hazro) to South China (Laren) and up to Japan for some species (i.e., Paradagmaritopsis). At Laren, Late Permian strata are generally characterized by Reichelina ex gr. simplex Sheng. Isolated samples of packstones, collected in Tsoteng region (Guangxi Province, South China), contain Sphaerulina sp. together with various smaller foraminifers and numerous representatives of the new species G. curiosa nov. sp. In this study we demonstrate that the regions of Zagros (Iran), Taurus (Turkey), South China and even Japan shared similar foraminiferal assemblages and represented intermittently connected palaeobiogeographic provinces during Late Permian times.     

<Emphasis Type="Italic">Mongousia</Emphasis>: A new productid genus (Brachiopoda) from the Permian of northeastern Mongolia

A new linoproductid genus is described from the provincial Terrakea arguta Zone (lower part of the Upper Kazanian Substage) of the key section of the Tsagan-Temete Horizon (Kazanian Stage-Lower Tatarian Substage) of northeastern Mongolia. The type species of the new genus was found in the middle layers of the Lower Uldza Subformation, which contains numerous diverse productids from the genus Terrakea.     

Synthèse sur la flore des nodules du Lagerstätte de Montceau-les-Mines (Carbonifère supérieur,France)

The flora from the Montceau-les-Mines Lagerstätte (Late Pennsylvanian, Stephanian, France) is preserved in small sideritic nodules and was studied in three locations in the (1) Saint-Louis, (2) Saint-François, and (3) Sainte-Hélène opencast mines. Qualitative and quantitative analyses of plant diversity and floristic composition in about 7000 nodules indicate substantial variations in the floral composition of these opencast mines. More than 50 taxa are recognized and belong to groups typical of the Late Carboniferous flora (lycopsids, sphenopsids, tree ferns, and pteridosperms). Arborescent sphenopsids and tree ferns were the major components at Saint-Louis, whereas the flora from Saint-François consisted mainly of pteridosperms; the one from Sainte-Hélène has a more balanced composition. Taphonomic and sedimentological data show that the flora contained in the nodules was hypoautochthonous to parautochthonous. The Montceau Basin displayed a mosaic of paleoenvironments (e.g., deltaic lacustrine, paludal to fluvial) which favored colonization by plants and animals.     

Termite coprolites (Insecta: Isoptera) from the Cretaceous of western France: A palaeoecological insight

This paper presents fossil faecal pellets - also named coprolites or frass - attributed to termites, which were found in amber and lignitic clay from the Wealden (Hauterivian-Barremian?), Late Albian and Early Cenomanian of south-western France. These coprolites have a characteristic subcylindrical shape and hexagonal transverse section and are assignable to Microcarpolithes hexagonalis Vangerow. The termite families that possibly produced these coprolites are discussed. The noticeable lack of termite attacks on the fossil wood associated with amber and lignitic clay is taphonomically analyzed in relation with the palaeoflora and palaeoclimate of these amber forests. The different medium where coprolites were found (amber, wood, sediments) suggests that primitive Cretaceous termites had already developed various biologies, such as wood or cryptic foraging, but probably not yet soil-feeding.     

A primitive anomodont therapsid from the base of the Beaufort Group (Upper Permian) of South Africa

Patranomodon nyaphulii , known from a nearly complete skull, lower jaw and partial postcranial skeleton, is morphologically the most primitive anomodont therapsid yet discovered. It is from the Eodicynodon Assemblage Zone, the lowest biozone of the Beaufort Group of South Africa, which has a primitive therapsid fauna comparable with that of the Russian Zone I. Patranaomodon is primitive with respect to other anomodonts in having short palatal exposure of the premaxilla, an unreduced tabular, a slit-like interpterygoidal vacuity, a screw-shaped jaw articulation (which precludes fore-aft sliding of the lower jaw), and only three sacral vertebrae. The poorly-known Galechirus and Galepus from the younger Cistecephalus Assemblage Zone appear to be at a comparably primitive evolutionary grade, and the three genera are tentatively united in the family Galechiridae. The taxon Dromasauria is shown to be paraphyletic and therefore should be discarded.     

New taxa of Mesorthopteridae (Insecta: Grylloblattida) from the Permian of Russia

New taxa of grylloblattids of the family Mesorthopteridae are described from the Permian of Russia: Parastenaropodites aquilonius sp. nov. from the Soyana locality (Middle Permian); P. circumhumatus sp. nov. from the Kul’chumovo locality; and Tshermyaninus biforis gen. et sp. nov., Permorthopteron foliaceus gen. et sp. nov., Parastenaropodites pannea sp. nov., P. exossis sp. nov., Mesoidelia procera sp. nov., and M. riphaea sp. nov. from the Isady locality (Upper Permian). Two species of the genus Khosaridelia Storozhenko, 1992 (family Permotermopsidae) and one species of the genus Megakhosarina Storozhenko, 1993 (family Megakhosaridae) are transferred to the genus Parastenaropodites Storozhenko, 1996 (family Mesorthopteridae); one species of the genus Parastenaropodites is transferred to the genus Austroidelia Riek, 1954; as a result, four new combinations are established: Khosaridelia rigida Aristov, 2005 =Parastenaropodites rigidus (Aristov, 2005), comb. nov. (Vorkuta locality, Lower Permian of Russia); Khosaridelia vyatica Aristov, 2009 =Parastenaropodites vyaticus (Aristov, 2009), comb. nov. (Karaungir locality, Middle Permian of Kazakhstan); Megakhosarina intricata Aristov, 2008 =Parastenaropodites intricatus (Aristov, 2008), comb. nov. (Soyana locality, Middle Permian of Russia); and Parastenaropodites nervosa Storozhenko, 1996 =Austroidelia nervosa (Storozhenko, 1996), comb. nov. (Madygen locality, Middle Triassic of Kyrgyzstan). An identification key to species of the genus Parastenaropodites is given.     

Le « Mégalosaure » (Dinosauria,Sauropoda) de Saint-Agnant (Charente-Maritime,France) : description et origine stratigraphique

The “Megalosaur” remains from Saint-Agnant (Charente-Maritime, France), reported as early as 1881 by Boissellier, are here described and figured for the first time. These bones, as well as a few additional specimens from the nearby locality of Soubise, belong in fact to an indeterminate sauropod. The stratigraphical position of these remains unambiguously indicates an infra-Cenomanian age. However, the presence in this area of continental deposits with Purbeckian and Wealden facies does not allow to decide between an earliest or late Early Cretaceous age.     

An ammonite–fish association from the Kimmeridgian (Upper Jurassic) of La Rochelle, western France

A partially disarticulated actinopterygian fish preserved in a large three-dimensional ammonite body chamber is described from the Kimmeridgian of western France. Taphonomic observations on the degree of preservation of the fish and the development of epibiont organisms on the inner wall of the shell indicate a rather long time interval before sediment totally filled the body chamber. The fish, referred to an indeterminate Macrosemiidae, probably used this empty ammonite ( Rasenioides , Aulacostephanidae) shell as a refuge, or possibly for spawning and/or brooding. It can be assumed that ammonite shells may have constituted common shelters for demersal fishes living in an open-marine shelf environment, near to a muddy bottom devoid of rocks.
