Abstract Geological studies in the northern sector of Chaco foreland Basin, Bolivia, yielded new fossils coming from late Oligocene-late Miocene Petaca Formation. Few fossil mammals were known Subandean Region Bolivia. We report a partially complete mandible hegetotheriid Hegetotheriinae (Notoungulata, Typotheria) Abapo (Rio Grande River). The specimen (YPFB-LIT-PAL-005) is very close size and ...

Rodents of the extant family Gliridae, commonly called dormice, are common in European faunas since early Eocene. Here we study for first time specimens from St-Martin-de-Castillon C (France, Oligocene) previously reported as Gliravus aff. majori and Pseudodryomys fugax. We now refer them to Butseloglis tenuis Microdyromys misonnei. Besides French material, new Montalbán 1D (Spain, studied. The...

The diversification of crown cetacean lineages (i.e., crown Odontoceti and crown Mysticeti) occurred throughout the Oligocene, but it remains an ongoing challenge to resolve the phylogenetic pattern of their origins, especially with respect to stem lineages. One extant monotypic lineage, Platanista gangetica (the Ganges and Indus river dolphin), is the sole surviving member of the broader group...

Abstract Extensive canyons, excavated into the margins of Levant Basin during Oligocene–Miocene, are interesting case-studies for canyon fills in carbonate settings. The Pattish Formation, developed along pre-evaporitic Messinian Beer Sheva Canyon Israel, was investigated using both onshore seismic imaging and field data. has three main facies fill (1) Subparallel reflections mimicking canyon´s...

The subsurface and surface structural geometries of the United Arab Emirates (UAE) fold-and-thrust belt (FTB) foreland basins are interpreted from seismic, well data, geology. Twelve horizons ranging in age Miocene to Lower Jurassic were mapped. Additionally, we outlined extent Sumeini Hawasina allochthonous nappes. tectonic subsidence curves suggest that final major passive margin rifting even...

Molecular data have converged on a consensus about the genus-level phylogeny of extant platyrrhine monkeys, but for most extinct taxa and certainly for those older than the Pleistocene we must rely upon morphological evidence from fossils. This raises the question as to how well anatomical data mirror molecular phylogenies and how best to deal with discrepancies between the molecular and morpho...

Hyptia deansi sp. nov. represents the first record of Evaniidae (Hymenoptera) from Lower Miocene to Upper Oligocene Mexican amber, Simojovel, Chiapas, Mexico and is described based on a well preserved female specimen. Phylogenetically relevant morphological characters are discussed with reference to fossil and extant genera of Evaniidae. The new fossil is placed in the extant New World genus Hy...

The E-vergent Northern Apennines formed by Oligocene-Miocene convergence and westward subduction of Adria beneath Europe. Extension ensued in the Mid-Late Miocene reflecting lower plate roll-back causing opening back-arc Tyrrhenian Sea. Post-orogenic extension is commonly advocated as main driver exhumation belt's inner domain high-pressure/low-temperature (HP-LT) rock units. Acquadolce Subunit...

Magnetic and gravimetric data from the central Alboran Sea allow identification of two axes of crustal thinning, which were probably active during the Oligocene—Early Miocene. The western Alboran basin axis is subparallel and may be related in origin to the Gibraltar Arc. The ENE—WSW trending Alboran Channel axis is probably intruded by basic igneous rocks and may represent the western end of t...
