Just out @ Alcheringa A new diminutive euphyllophyte from the Middle Devonian of West Junggar, Xinjiang, China and its evolutionary implications Author(s) Hong-He Xu, Yao Wang, Peng Tang & Yi Wang Abstract: A diminutive euphyllophyte, Douaphyton levigata gen. et sp. nov., is described from the upper Middle Devonian (Givetian) Hujiersite Formation of West Junggar, Xinjiang, China. The plant consists of more than three orders of axis branching, each axis being less

Just out @ Palaeogeography, Palaeoclimatology, Palaeoecology Conodont diversity across the late Eifelian Kačák Episode of the southern Alpine realm (central Carnic Alps, Austria/Italy) Author(s) Thomas J. Suttner, Erika Kido, Carlo Corradini, Stanislava Vodrážková, Monica Pondrelli, Luca Simonetto Abstract: The polyphased Kačák Episode near the Eifelian-Givetian boundary (Middle Devonian), well documented globally, resembles other global biotic extinction events driven by climate change. High-resolution conodont biodiversity patterns from shallow marine, slope and

Just out | First report of Devonian bactritids (Cephalopoda) from South America: paleobiogeographic and biostratigraphic implications @ Journal of Paleontology

Just out @ Journal of Paleontology First report of Devonian bactritids (Cephalopoda) from South America: paleobiogeographic and biostratigraphic implications Author(s) Marcela Cichowolski, Juan J. Rustán Abstract: Devonian bactritids are described for the first time from South America. They come from siliciclastic rocks of the Talacasto Formation in the Precordillera Basin, west-central Argentina. The host strata span the Lochkovian–Emsian and contain other non-ammonoid cephalopods as well, thus refuting the alleged virtual absence

Andrew Beard, Andrew M. Bush, Anjali M. Fernandes, Patrick R. Getty, Michael T. Hren Abstract: Two pulses of extinction in the late Frasnian (Late Devonian), the Lower and Upper Kellwasser (LKW and UKW) events, coincided with the deposition of organic-rich strata in many parts of the world, including

Just out @ Lethaia An integrative ichnological and taphonomic approach in a transgressive–regressive cycle: a case study from Devonian of Paraná Basin, Brazil Author(s) Daniel Sedorko, Elvio P. Bosetti, Renata G. Netto Abstract: The palaeoenvironmental context of a section of the Devonian Ponta Grossa Formation (Paraná Basin) was examined using an integrated ichnological and taphonomic approach. Three taphofacies (T-A, T-B and T-C) and six ichnofabrics are recognized. T-A is mainly

Just out | A Lower Devonian hexacrinitid crinoid (Camerata, Monobathrida) from south-west England @ PalZ

Just out @ PalZ A Lower Devonian hexacrinitid crinoid (Camerata, Monobathrida) from south-west England Author(s) Stephen K. Donovan, Fiona E. Fearnhead Abstract: The most species-rich and widespread crinoid clade in the type area of the Devonian of south-west England is the monobathrid camerate family Hexacrinitidae Wachsmuth and Springer. These crinoids occur either as thecae (Middle Devonian) or pluricolumnals and columnals (Lower to Upper Devonian). The first new, nominal species of hexacrinitid, probably Oehlerticrinus Le Menn, to

The new whiplash dinosaur from Wyoming | New Species Reported This Week

It was Galeamopus pabsti’s week. The new whiplash dinosaur, a sauropod from the Upper Jurassic of the northern Bighorn Basin in Wyoming (USA), reported in the beginning of this week in Peer J, made headlines all over the world. The identification of this new species was based on the reexamination of a previously found specimen, currently on display at the Aathal Dinosaur Museum, outside Zurich, Switzerland. The researchers took a good look at the museum mainstay and realized it was a previously undescribed species with often-subtle differences from G. hayi, a sauropod they had studied before.

Basinger & Jinzhuang Xue Abstract: Sphenophyllum was an important and long-surviving sphenopsid genus in the Paleozoic floras, with a worldwide distribution. A new species, Sphenophyllum changxingense sp. nov., is described from the Upper Devonian Wutong Formation of Changxing County, Zhejiang

Just out @ Palaeogeography, Palaeoclimatology, Palaeoecology Behavioural asymmetry in Devonian trilobites Author(s) Rui-wen Zong , Yiming Gong Abstract: The cephalon of the trilobite Phacopidae was usually separated from the thorax during moulting, and abandoned near the trunk. We statistically evaluated the distribution pattern of the cephala of Omegops cornelius, and found that near 70% of the total cephala were displaced on the right side, from the Upper Devonian deposits of the
