Just out @ Bulletin of Geosciences Revision of Dendraena pinnatilobata Němejc from the Pennsylvanian of the Czech Republic Author(s) Frojdova J, Pšenička J, Bek J, Martinek K Abstract: Dendraena pinnatilobata Němejc is a Pennsylvanian true fern, which is known from the Stradonice locality (Czech Republic) only. All specimens of Dendraena pinnatilobata are preserved as three-dimensionally in volcaniclastic of Whestone Horizon (Radnice Member, Kladno Formation). Revision of this species includes detail

Heintzman, Lee Newsom, Nancy H. Bigelow, Matthew J. Wooller, Beth Shapiro, John W. Williams Abstract: Aim The Bering Land Bridge (BLB) connected Asia and North America during glacial periods, supported a diverse ecosystem of now-vanished megafauna, and is a proposed glacial refugium.

On the News | Antarctica was once green @Nerve.in

On the News @ Nerve.in Title:  Antarctica was once green Excerpt: “Nearly 300 million years ago, the frozen, inhospitable Antarctica was covered by lush subtropical forests, according to scientists. That Antarctica was once green is a matter of consensus among scientists, but still unknown to many people, Marcelo Leppe, a paleontologist who works with the Chilean Antarctic National Institute, told Efe news on Friday. Leppe, Chile’s representative to the international

Just out @ Rivista Italiana di Paleontologia e Stratigrafia Middle Triassic Amber Associated with Voltzialean Conifers from the Southern Alps of Italy Author(s) Guido Roghi, Evelyn Kustatscher, Eugenio Ragazzi, Luca Giusberti Abstract: Amber from the Carnian succession of the Dolomites and Julian Alps (northeastern Italy) represents one of the most ancient and quantitatively substantial Triassic fossil resin records in the world. So far, the Carnian appeared to be the only

Just out @ Historical Biology Small Celastraceae and Polygonaceae twigs from the Upper Cenozoic (Ituzaingó Formation) of the La Plata Basin, Argentina Author(s) María Jimena Franco Abstract: Two new wood types from the Late Cenozoic of the Ituzaingó Formation, La Plata Basin, Northeast Argentina add to our knowledge of South American Cenozoic plants. The materials were preserved by siliceous cellular permineralization, and they were prepared for microscopic examination by surface

Just out @ BMC Evolutionary Biology Eobowenia gen. nov. from the Early Cretaceous of Patagonia: indication for an early divergence of Bowenia? Author(s) Mario Coiro and Christian Pott Abstract: Background Even if they are considered the quintessential “living fossils”, the fossil record of the extant genera of the Cycadales is quite poor, and only extends as far back as the Cenozoic. This lack of data represents a huge hindrance for the

Just out @ BMC Evolutionary Biology Fossils matter: improved estimates of divergence times in Pinus reveal older diversification Author(s) Bianca Saladin, Andrew B. Leslie, Rafael O. Wüest, Glenn Litsios, Elena Conti, Nicolas Salamin and Niklaus E. Zimmermann Abstract: Background The taxonomy of pines (genus Pinus) is widely accepted and a robust gene tree based on entire plastome sequences exists. However, there is a large discrepancy in estimated divergence times of major

Just out @ Nature Scientific Reports The demographic response of a deciduous shrub (the Indigofera bungeana complex, Fabaceae) to the Pleistocene climate changes in East Asia Author(s) Xue-Li Zhao, Xin-Fen Gao, Zhang-Ming Zhu, Yun-Dong Gao & Bo Xu Abstract: East Asia harbors the highest level of floristic diversity among the world’s temperate regions. Despite the increase in phylogeographic studies of temperate plants in East Asia, far less attention has been paid

Just out @ Neues Jahrbuch für Geologie und Paläontologie Cedroxylon lesbium (Unger) Kraus from the Petrified Forest of Lesbos, lower Miocene of Greece and its possible relationship to Cedrus Author(s) Mantzouka, Dimitra; Karakitsios, Vasileios; Sakala, Jakub Abstract: The Petrified Forest of Lesbos has been the subject of the palaeobotanical research since the 19th century, but a number of inconsistencies still remain. One of them concerns the fossils described over 100 years ago
