Just out @ PLOS one From body scale ontogeny to species ontogeny: Histological and morphological assessment of the Late Devonian acanthodian Triazeugacanthus affinis from Miguasha, Canada Author(s) Marion Chevrinais, Jean-Yves Sire, Richard Cloutier Abstract: Growth series of Palaeozoic fishes are rare because of the fragility of larval and juvenile specimens owing to their weak mineralisation and the scarcity of articulated specimens. This rarity makes it difficult to describe early vertebrate growth patterns

On the News @ Montana Standard Title:  “About the size of a cow” New prehistoric sea creature discovered after Montana hunter finds exposed fossils Excerpt: “A fossil found by an elk hunter in Montana nearly seven years ago has led to the discovery of a new species of prehistoric sea creature that lived about 70 million years ago in the inland sea that flowed east of the Rocky Mountains. The

Just out @ Contributions from the Museum of Paleontology, University of Michigan Moabosaurus Utahensis, N. gen., N. SP., A New Sauropod From The Early Cretaceous (Aptian) of North America Author(s) Britt, Brooks B.; Scheets, Rodney D.; Whiting, Michael F.; Wilhite, D. Ray Abstract: The Early Cretaceous was a time of dramatic change for sauropod dinosaurs in North America. Between the Late Jurassic-aged Morrison Formation and overlying Early Cretaceous strata, there was

Just out @ PeerJ Rates of morphological evolution in Captorhinidae: an adaptive radiation of Permian herbivores Author(s) Neil Brocklehurst Abstract: The evolution of herbivory in early tetrapods was crucial in the establishment of terrestrial ecosystems, although it is so far unclear what effect this innovation had on the macro-evolutionary patterns observed within this clade. The clades that entered this under-filled region of ecospace might be expected to have experienced an

On the News @ Ecns.cn Title:  Fossils of world’s most pricey pet fish discovered Excerpt: “Scientists have discovered early fossil remains tracing the ancestry of one of the world’s most expensive aquarium fish – the endangered Asian arowana. The discoveries in Central China’s Hunan and Hubei provinces are helping scientists understand how this prized fish spread throughout the world, read the latest edition of Vertebrata Palasiatica. The species, Scleropages sinensis,

On the News @ The Conversation Title:  Dragon-like fossil discovery could change our view of dinosaur origins Excerpt: “What did the ancestors of dinosaurs look like? For decades, our knowledge of close dinosaur relatives has been based largely on animals like the Triassic Period reptile Marasuchus, a tiny, squirrel-sized critter that moved rapidly on two legs. Dinosaur ancestors, according to the conventional story, looked much like dinosaurs, just shrunken down to

Just out | Morphological and histological evidence for the oldest known softshell turtles from Japan @ Journal of Vertebrate Paleontology

Just out @ Journal of Vertebrate Paleontology Morphological and histological evidence for the oldest known softshell turtles from Japan Author(s) Yasuhisa Nakajima, Igor G. Danilov, Ren Hirayama, Teppei Sonoda & Torsten M. Scheyer Abstract: Herein we report morphologically and histologically diagnostic trionychid specimens from the Barremian–Aptian (129.4–113.0 Ma) of Japan. One specimen (FPDM-V9487) is an associated skeleton that consists of a scapula, a humerus, an ischium, and hypoplastra. The limb and

Author(s) Stephen J. Godfrey, Lawrence G. Barnes & Olivier Lambert Abstract: On the basis of an assigned specimen (USNM 526604, from the Plum Point Member of the Calvert Formation, Early Miocene, Maryland, U.S.A.), Araeodelphis natator Kellogg, is referred to the Platanistidae. A phylogenetic analysis identifies A. natator

Just out @ Journal of Vertebrate Paleontology A new elasmosaurid (Sauropterygia, Plesiosauria) from the Bearpaw Shale (Late Cretaceous, Maastrichtian) of Montana demonstrates multiple evolutionary reductions of neck length within Elasmosauridae Author(s) Danielle J. Serratos, Patrick Druckenmiller & Roger B. J. Benson Abstract: Plesiosauria is a diverse clade of marine reptiles that have been studied since the early 19th century. However, phylogenetic relationships within the group have been contentious due to limited
