Just out @ Nature Ecology and Evolution Molecular fossils from organically preserved Ediacara biota reveal cyanobacterial origin for Beltanelliformis Author(s) Ilya Bobrovskiy, Janet M. Hope, Anna Krasnova, Andrey Ivantsov & Jochen J. Brocks Abstract: The Ediacara biota (~575–541 million years ago) mark the emergence of large, complex organisms in the palaeontological record, preluding the radiation of modern animal phyla. However, their phylogenetic relationships, even at the domain level, remain controversial. We report the discovery of molecular

Bernor Abstract: Herein, the authors report on skulls, mandibles and postcranial specimens of two species of Chinese Sivalhippus, S. ptychodus and S. platyodus. We frame our description and analyses within the context of newly described characters of the cheek teeth of Hippotherium from the Pannonian

Just out @ Lethaia The Great Ordovician Biodiversification Event (GOBE): definition, concept and duration Author(s) Thomas Servais, David A.T. Harper Abstract: The Ordovician biodiversification has been recognized since the 1960s; the term ‘The Great Ordovician Biodiversification Event’, abbreviated by many as the ‘GOBE’, has been used for the past 20 years. The conceptual development and terminology applied to this crucial episode in marine life signify its considerable complexity. The GOBE includes

Just out @ Historical Biology A catalogue of teleosauroids (Crocodylomorpha: Thalattosuchia) from the Toarcian and Bajocian (Jurassic) of southern Luxembourg Author(s) Michela M. Johnson, Mark T. Young, Stephen L. Brusatte, Ben Thuy & Robert Weis Abstract: Teleosauroids were a clade of semi-marine crocodylomorphs that attained near-global distribution during the Jurassic Period. They were particularly common during the Toarcian (Early Jurassic) and are well documented throughout the UK and Germany. However, Toarcian teleosauroids

Just out @ Journal of Mammalian Evolution Morphology of the Middle Ear Ossicles in the Rodent Perimys (Neoepiblemidae) and a Comprehensive Anatomical and Morphometric Study of the Phylogenetic Transformations of these Structures in Caviomorphs Author(s) Leonardo Kerber, Marcelo R. Sánchez-Villagra Abstract: The extinct clade of caviomorph rodents Neoepiblemidae includes forms that lived in South America from the early Miocene to Pliocene. Among them is Perimys. The exceptional preservation of ear ossicles in this rodent is described and analyzed in

On the News | Mexico | Dinosaur Tail Sold in Mexico Auction Sparks Controversy @ I4U News

On the News @ I4U News Title:  Dinosaur Tail Sold in Mexico Auction Sparks Controversy EFE Excerpt: “Moroccan authorities have opened an urgent investigation into the apparent trafficking of a rare Moroccan dinosaur fossil. In January, a 160 million-year old Moroccan dinosaur tail was put up for auction in Mexico. The fossil was later sold to an anonymous buyer at around $95,000. Now, Moroccan authorities have opened an investigation to

Just out @ Marine Micropaleontology Variability in diatom and silicoflagellate assemblages during mid-Pliocene glacial-interglacial cycles determined in Hole U1361A of IODP Expedition 318, Antarctic Wilkes Land Margin Author(s) Linda H. Armbrecht, Vikki Lowe, Carlota Escutia, Masao Iwai, Robert McKay, Leanne K. Armanda Abstract: The Earth is currently experiencing climatic changes that will result in similar environmental conditions to those experienced during the mid-Pliocene (5.3–3.6 million years ago [Ma]), such as similar atmospheric CO2 concentrations, elevated sea surface

Just out @ Proceedings of the Royal Society B Lizards of the lost arcs: mid-Cenozoic diversification, persistence and ecological marginalization in the West Pacific Author(s) Paul M. Oliver, Rafe M. Brown, Fred Kraus, Eric Rittmeyer, Scott L. Travers, Cameron D. Siler Abstract: Regions with complex geological histories often have diverse and highly endemic biotas, yet inferring the ecological and historical processes shaping this relationship remains challenging. Here, in the context of the taxon cycle model

Just out @ Proceedings of the Royal Society B The evolution of tail weaponization in amniotes Author(s) Victoria M. Arbour, Lindsay E. Zanno Abstract: Weaponry, for the purpose of intraspecific combat or predator defence, is one of the most widespread animal adaptations, yet the selective pressures and constraints governing its phenotypic diversity and skeletal regionalization are not well understood. Here, we investigate the evolution of tail weaponry in amniotes, a rare
