A Late Miocene Terrestrial Temperature History for the Northeastern Tibetan Plateau's Period of Tectonic Expansion

Geophysical Research Letters, 2019
During the Late Miocene, the climate patterns and ecosystems of continental land masses experienced crucial transitions, but whether the principal driver was regional tectonic forcing or a decline in CO2 concentrations remains debated.

Solenostomus snuffleupagus sp. nov., a hairy ghost pipefish (Teleostei: Solenostomidae) from the Southwest Pacific, with an integrative comparison to S. paegnius

Journal of Fish Biology, EarlyView.
Abstract A new species of ghost pipefish, Solenostomus snuffleupagus sp. nov., is described from the Coral Sea based on specimens (18–34 mm SL) collected from coral reef habitats in Queensland, Australia. The species is diagnosed by the following combination of characters: abundant elongate integumentary filaments imparting a conspicuously shaggy ...

Tooth morphology of deep‐water catsharks of the genus Apristurus (Chondrichthyes: Pentanchidae) in the North Atlantic Ocean

Journal of Fish Biology, EarlyView.
Abstract The deep‐water catshark family (Pentanchidae) is the most species‐rich family among extant shark lineages. Within this family, the genus Apristurus is the largest, comprising small, deep‐sea species characterised by elongated bodies and dorso‐ventrally compressed snouts. Five Apristurus species are currently recognised from the North Atlantic,

The late Miocene ¹⁰Be anomaly and the possibility of a supernova

Astronomy & Astrophysics
Recent measurements of cosmogenic 10Be in deep-ocean ferromanganese crusts from the central and northern Pacific have revealed an anomalous concentration between 11.5 and 9.0 Myr ago, peaking at 10.1 Myr. One possible explanation is a nearby supernova (SN) event.

Cryptic diversity and recent diversification in the Pyrrhulina australis species complex (Characiformes, Lebiasinidae) revealed by mitochondrial DNA

Journal of Fish Biology, EarlyView.
Abstract Pyrrhulina australis Eigenmann & Kennedy, 1903, is widely distributed across the main hydrographic basins of South America. The taxonomic integrity of this species is nevertheless challenged by the lack of clear diagnostic characters, its marked geographic variation and the morphological overlap with its congeners. In this context, the present

Rhododendron diversity patterns provide new insights for conserving China's montane flora

Journal of Integrative Plant Biology, EarlyView.
Integrating distribution, phylogenetic, and functional trait data for 603 Rhododendron species in China identified significant conservation hotspots of multidimensional diversity, particularly in the Hengduan Mountains. Climate seasonality and topographic heterogeneity jointly influenced these patterns; however, notable conservation gaps remained ...

Postcranial anatomy of the Miocene hippopotamoids of Toros‐Menalla, Chad

Journal of Anatomy, EarlyView.
We establish a framework for the identification of postcranial remains in hippopotamoids by describing and comparing for the first time two late Miocene hippopotamoids from Toros‐Menalla, Chad (Hexaprotodon garyam, an early hippopotamid, and Libycosaurus bahri, the last African anthracothere) with the common hippopotamus.

Late Miocene magnetostratigraphy in the Mediterranean

, 1984
Reversals of the geomagnetic field In the geological past are recorded globally in the natural remanent magnetization (NRM) of igneous and sedimentary rock sequences. The accurate and rei iable reconstruction of this record is the basis of magnetostratigraphy.

Computed tomography reveals the endocranial anatomy of Crocodylia: Implications for phylogenetic relationships and ecomorphological convergence across Crocodylomorpha

Journal of Anatomy, EarlyView.
The evaluation of the endocranial anatomy of 43 crocodylian species reveals several differences, including variation in the curvature of the encephalic endocast, the size of the endosseous labyrinth and paratympanic sinuses, and the presence of additional snout sinuses.

Eustatic and tectonic change effects in the reversion of the transcontinental Amazon River drainage system

Brazilian Journal of Geology
: The development of the transcontinental Amazon River System involved geological events in the Andes Chain; Vaupés, Purus and Gurupá arches; sedimentary basins of the region and sea level changes. The origin and age of this river have been discussed for
