Two new opilionid species from suborder Cyphophthalmi, family Sironidae, Siro franzi Karaman & Raspotnig sp. nov. and ozimeci nov., Austria Croatia respectively, are described illustrated. Both show a close relation to two other relict sironid the southern eastern parts of Alps, valleorum crassus. All four treated here as monophyletic, alpine group genus Siro, opposed remaining European...

The Quintanilla la Ojada section (Basque-Cantabrian Region, northern Spain) has yielded two assemblages of Late Cretaceous vertebrates, deposited during the Maastrichtian in coastal environments and related to a transgressive lag at base Valdenoceda Formation. Numerous teeth Elasmobranchii Actinopterygii are most prevailing fossil material, although scarce marine reptiles (Mosasauridae) dinosau...

Three-dimensional numerical ocean circulation model experiments that were designed to evaluate the circulation characteristics for the mid-Cretaceous ( approximately 100 million years ago) show that the primary direction of flow through the Tethys Ocean was eastward; in contrast, a westward flowing circumglobal Tethys current has been a consistent feature of earlier reconstructions of Cretaceou...

The deep ocean conditions and circulation during the Cretaceous have been characterized mainly by the sediments from the Tethys Sea and the proto-Atlantic Ocean, because sedimentological data from the Pacific basin from that period have been quite limited. Here we present new geochemical measurements from sediments that we collected from two sites in Hokkaido, Japan, that were presumably deposi...

In order to understand the potential controls on Asian tectonics during the subduction of the Tethys and Indian lithospheres, we reconstruct the coupled subduction-continent deformation history using tomographic imaging, kinematics constraints and numerical modeling. The global P-waves tomographic images of the mantle below the India-Asia collision zone provide constraints on the deep structure...

A detailed study of calcareous nannofossil assemblages from twelve uppermost lower Barremian–lower Aptian sections in the Subbetic Domain Betic Cordillera was performed. Seven new species (Crucibiscutum bastetanum, Crucibiscutum gracile, Chiastozygus lamprostauros, Cyclagelosphaera platyaspis, Lithraphidites aichmoides, pugio, and Rhagodiscus sicutclipeus) are described, one is emended (Lithrap...

The prevailing idea for the geologic evolution of the western Mediterranean in the Cenozoic is based on north dipping subduction near the gulf of Lyon undergoing vigorous rollback since ∼30 Ma as a consequence of slow Africa–Eurasia convergence across the ∼130 My old Alpine Tethys oceanic lithosphere (Lonergan and White, 1997; Malinverno and Ryan, 1986; Royden, 1993). As rollback propagated sou...

A new gastropod fauna of Burdigalian (early Miocene) age is described from the Iranian part of Makran. The fauna comprises 19 species and represents three distinct assemblages from turbid water coral reef, shallow subtidal soft-bottom and mangrove-fringed mudflat environments in the northern Indian Ocean. Especially the reef-associated assemblage comprises largely new species. This is explained...
