Th is study was carried out in order to determine the species of the subfamily Opiinae in Turkey. Between 1991 and 2008, malaise and light traps and sweeping nets were used to obtain adult specimens from various habitats in Turkey. A total of 116 species from 7 genera and 28 subgenera of the Opiinae were determined, and 45 of these species were new records for the Turkish fauna. Th e distribution of the species was evaluated taking into consideration the zoogeographic regions and phytogeographic provinces of Turkey. © TÜBİTAK. Source


Based on the morphology of the aperture and internal plaits or folds, the Nerineoidea Zittel, 1873 are subdivided into seven families: the Pseudonerineidae Pchelintsev, 1965, Ceritellidae Wenz, 1940, Nerinellidae Pchelintsev, 1960, Eunerineidae n. fam. (new family that includes the Nerineidae Zittel, 1873 (pars) and the Diptyxidae Bouchet & Rocroi, 2005) the Ptygmatididae Pchelintsev, 1960, Nerineidae and Itieriidae Cossmann, 1896. The internal plaits of the Nerineoidea had different functions: the columellar plaits subdivided the columellar muscle into strands, which allowed portions of the foot to be moved individually. A tubelike space delimited by the parietal and palatal plaits is compared with the pallial caecum or posterior mantle chamber of heterobranchs and served the respiration. Waste from both mantle chambers was expelled through a subsutural notch, which is the common feature of the Nerineoidea. The Nerineoidea were shell draggers and probably deposit feeders with a semi- infaunal mode of life. The “Lower Heterobranchia” represented by the Streptacidoidea Knight, 1931, Nerineoidea and Acteonelloidea Akopjan, 1976 cluster outside the Euthyneura Knight, 1931. The Acteonelloidea, the second group of large Heterobranchia are related to the Nerineoidea and cannot be part of the Acteonoidea. The extinction of the Eunerineidae n. fam., the Ptygmatididae and Ceritellidae in the Late Cenomanian was caused by a general warming in low latitudes. The Acteonellidae genus Trochactaeon Meek, 1863 replaced the extinct Eunerineidae n. fam. ecologically in shallow marine soft-bottom environments and became extinct itself in the Lower Campanian due to the general cooling. In the Caribbean palaeobiological province, the endemic Nerineoidea genus Plesioptygmatis Boese, 1906 extended stratigraphically to the basal Late Maastrichtian. Acteonella d’Orbigny, 1842 and the endemic Acteonellidae genus Mexicotrochactaeon Akopjan, 1972 ranged upwards into the Late Maastrichtian. © Publications Scientifiques du Muséum national d’Histoire naturelle, Paris.

Presented here is the complete proboscidean assemblage from the vertebrate locality of Sandelzhausen (southern Germany), dated to the Early/Middle Miocene boundary, early middle MN5. The material is preserved as mostly isolated and disarticulated remains and is composed of about 200 dental remains (cheek teeth and tusks), cranial fragments, and postcrania. The main part of this assemblage is identified as belonging to Gomphotherium subtapiroideum (Schlesinger, 1917), and a few specimens are attributed to Zygolophodon turicensis (Schinz, 1824). Remarkable is the high percentage of remains of young individuals in this proboscidean assemblage and the lack of Prodeinotherium Éhik, 1930. The rich material of G. subtapiroideum enables the description of some tooth positions not known before for this taxon. Furthermore, morphological and metrical comparisons with material of more or less contemporaneous taxa from other European localities are provided, especially G. angustidens (Cuvier, 1817), G. sylvaticum Tassy, 1985, and "Trilophodon" ratisbonensis Rinnert, 1956. © Springer-Verlag 2010.

The segmented growth of the Markgrafneusiedl normal fault in the late Miocene clastic sediments of the central Vienna Basin (Austria) was investigated by construction of a detailed three-dimensional (3D) structural model. Using high resolution 3D seismic data, the fault surface and marker horizons in the hanging wall and the footwall of the Markgrafneusiedl Fault were mapped and orientation, displacement and morphology of the fault surface were quantified. Individual, fault segments were identified by direct mapping of the deflection of the marker horizons close to the fault surface. Correlating the size of the identified segments with the magnitude of fault drag and displacement distribution showed that fault evolution progressed in several stages. The proposed method allows the detection of segments that are not recorded by the magnitude of displacement or fault morphology. Most importantly, detailed mapping of marker deflections in the hanging wall could help to constrain equivalent structures in the footwall, which may represent potential hydrocarbon traps. © 2013 Elsevier Ltd.
