EXHIBITION BY LUIS V. REY & GONDWANA STUDIOS HORNS, SPIKES, QUILLS AND FEATHERS. THE SECRET IS IN THE SKIN! Not long ago, our knowledge of dinosaurs was based almost completely on the assumptions we made from their internal body structure. Bones and possible muscle and tendon attachments were what scientists used mostly for reconstructing their anatomy. The rest, including the colours, were left to the imagination… and needless to say the skins were lizard-like and the colours grey, green and brown prevailed. We are breaking the mould with this Dinosaur runners, massive horned faces and Revolution! tank-like monsters had to live with and defend themselves against the teeth and claws of the Thanks to a vast web of new research, that this Feathery Menace... a menace that sometimes time emphasises also skin and ornaments, we reached gigantic proportions in the shape of are now able to get a glimpse of the true, bizarre Tyrannosaurus… or in the shape of outlandish, and complex nature of the evolution of the massive ornithomimids with gigantic claws Dinosauria. like the newly re-discovered Deinocheirus, reconstructed here for the first time in full.

D Inosaur Paleobiology
Topics in Paleobiology The study of dinosaurs has been experiencing a remarkable renaissance over the past few decades. Scientifi c understanding of dinosaur anatomy, biology, and evolution has advanced to such a degree that paleontologists often know more about 100-million-year-old dinosaurs than many species of living organisms. This book provides a contemporary review of dinosaur science intended for students, researchers, and dinosaur enthusiasts. It reviews the latest knowledge on dinosaur anatomy and phylogeny, Brusatte how dinosaurs functioned as living animals, and the grand narrative of dinosaur evolution across the Mesozoic. A particular focus is on the fossil evidence and explicit methods that allow paleontologists to study dinosaurs in rigorous detail. Scientifi c knowledge of dinosaur biology and evolution is shifting fast, Dinosaur and this book aims to summarize current understanding of dinosaur science in a technical, but accessible, style, supplemented with vivid photographs and illustrations. Paleobiology Dinosaur The Topics in Paleobiology Series is published in collaboration with the Palaeontological Association, Paleobiology and is edited by Professor Mike Benton, University of Bristol. Stephen Brusatte is a vertebrate paleontologist and PhD student at Columbia University and the American Museum of Natural History. His research focuses on the anatomy, systematics, and evolution of fossil vertebrates, especially theropod dinosaurs. He is particularly interested in the origin of major groups such Stephen L. Brusatte as dinosaurs, birds, and mammals. Steve is the author of over 40 research papers and three books, and his work has been profi led in The New York Times, on BBC Television and NPR, and in many other press outlets. -
Late Jurassic Theropod Dinosaur Bones from the Langenberg Quarry
Late Jurassic theropod dinosaur bones from the Langenberg Quarry (Lower Saxony, Germany) provide evidence for several theropod lineages in the central European archipelago Serjoscha W. Evers1 and Oliver Wings2 1 Department of Geosciences, University of Fribourg, Fribourg, Switzerland 2 Zentralmagazin Naturwissenschaftlicher Sammlungen, Martin-Luther-Universität Halle-Wittenberg, Halle (Saale), Germany ABSTRACT Marine limestones and marls in the Langenberg Quarry provide unique insights into a Late Jurassic island ecosystem in central Europe. The beds yield a varied assemblage of terrestrial vertebrates including extremely rare bones of theropod from theropod dinosaurs, which we describe here for the first time. All of the theropod bones belong to relatively small individuals but represent a wide taxonomic range. The material comprises an allosauroid small pedal ungual and pedal phalanx, a ceratosaurian anterior chevron, a left fibula of a megalosauroid, and a distal caudal vertebra of a tetanuran. Additionally, a small pedal phalanx III-1 and the proximal part of a small right fibula can be assigned to indeterminate theropods. The ontogenetic stages of the material are currently unknown, although the assignment of some of the bones to juvenile individuals is plausible. The finds confirm the presence of several taxa of theropod dinosaurs in the archipelago and add to our growing understanding of theropod diversity and evolution during the Late Jurassic of Europe.

An Ankylosaurid Dinosaur from Mongolia with in Situ Armour and Keratinous Scale Impressions
An ankylosaurid dinosaur from Mongolia with in situ armour and keratinous scale impressions VICTORIA M. ARBOUR, NICOLAI L. LECH−HERNES, TOM E. GULDBERG, JØRN H. HURUM, and PHILIP J. CURRIE Arbour, V.M., Lech−Hernes, N.L., Guldberg, T.E., Hurum, J.H., and Currie P.J. 2013. An ankylosaurid dinosaur from Mongolia with in situ armour and keratinous scale impressions. Acta Palaeontologica Polonica 58 (1): 55–64. A Mongolian ankylosaurid specimen identified as Tarchia gigantea is an articulated skeleton including dorsal ribs, the sacrum, a nearly complete caudal series, and in situ osteoderms. The tail is the longest complete tail of any known ankylosaurid. Remarkably, the specimen is also the first Mongolian ankylosaurid that preserves impressions of the keratinous scales overlying the bony osteoderms. This specimen provides new information on the shape, texture, and ar− rangement of osteoderms. Large flat, keeled osteoderms are found over the pelvis, and osteoderms along the tail include large keeled osteoderms, elongate osteoderms lacking distinct apices, and medium−sized, oval osteoderms. The specimen differs in some respects from other Tarchia gigantea specimens, including the morphology of the neural spines of the tail club handle and several of the largest osteoderms.

www.nature.com/scientificreports OPEN New Australian sauropods shed light on Cretaceous dinosaur palaeobiogeography Received: 15 April 2016 Stephen F. Poropat1,2,*,, Philip D. Mannion3,*, Paul Upchurch4,*, Scott A. Hocknull5, Accepted: 13 September 2016 Benjamin P. Kear1,6, Martin Kundrát7,8, Travis R. Tischler2, Trish Sloan2, George H. K. Sinapius2, Published: 20 October 2016 Judy A. Elliott2 & David A. Elliott2 Australian dinosaurs have played a rare but controversial role in the debate surrounding the effect of Gondwanan break-up on Cretaceous dinosaur distribution. Major spatiotemporal gaps in the Gondwanan Cretaceous fossil record, coupled with taxon incompleteness, have hindered research on this effect, especially in Australia. Here we report on two new sauropod specimens from the early Late Cretaceous of Queensland, Australia, that have important implications for Cretaceous dinosaur palaeobiogeography. Savannasaurus elliottorum gen. et sp. nov. comprises one of the most complete Cretaceous sauropod skeletons ever found in Australia, whereas a new specimen of Diamantinasaurus matildae includes the first ever cranial remains of an Australian sauropod. The results of a new phylogenetic analysis, in which both Savannasaurus and Diamantinasaurus are recovered within Titanosauria, were used as the basis for a quantitative palaeobiogeographical analysis of macronarian sauropods. Titanosaurs achieved a worldwide distribution by at least 125 million years ago, suggesting that mid-Cretaceous Australian sauropods represent remnants of clades which were widespread during the Early Cretaceous. These lineages would have entered Australasia via dispersal from South America, presumably across Antarctica. High latitude sauropod dispersal might have been facilitated by Albian–Turonian warming that lifted a palaeoclimatic dispersal barrier between Antarctica and South America. -

Was Dinosaurian Physiology Inherited by Birds? Reconciling Slow Growth in Archaeopteryx

It is believed that the growth and energetic physiology of basalmost birds such as Archaeopteryx were inherited in their entirety from non-avialan dinosaurs. This hypothesis predicts that the long bones in these birds formed using rapidly growing, well-vascularized woven tissue typical of non-avialan dinosaurs. Methodology/Principal Findings: We report that Archaeopteryx long bones are composed of nearly avascular parallel- fibered bone. This is among the slowest growing osseous tissues and is common in ectothermic reptiles. These findings dispute the hypothesis that non-avialan dinosaur growth and physiology were inherited in totality by the first birds. Examining these findings in a phylogenetic context required intensive sampling of outgroup dinosaurs and basalmost birds. Our results demonstrate the presence of a scale-dependent maniraptoran histological continuum that Archaeopteryx and other basalmost birds follow. -
A New Caenagnathid Dinosaur from the Upper Cretaceous Wangshi

Here we report a new oviraptorosaur, Anomalipes zhaoi gen. et sp. nov., based on a recently collected specimen comprising a partial left hindlimb from the Kugou Locality in Zhucheng. This specimen’s systematic position was assessed by three numerical cladistic analyses based on recently published theropod phylogenetic datasets, with the inclusion of several new characters. Anomalipes zhaoi difers from other known caenagnathids in having a unique combination of features: femoral head anteroposteriorly narrow and with signifcant posterior orientation; accessory trochanter low and confuent with lesser trochanter; lateral ridge present on femoral lateral surface; weak fourth trochanter present; metatarsal III with triangular proximal articular surface, prominent anterior fange near proximal end, highly asymmetrical hemicondyles, and longitudinal groove on distal articular surface; and ungual of pedal digit II with lateral collateral groove deeper and more dorsally located than medial groove. The holotype of Anomalipes zhaoi is smaller than is typical for Caenagnathidae but larger than is typical for the other major oviraptorosaurian subclade, Oviraptoridae. Size comparisons among oviraptorisaurians show that the Caenagnathidae vary much more widely in size than the Oviraptoridae. Oviraptorosauria is a clade of maniraptoran theropod dinosaurs characterized by a short, high skull, long neck and short tail. -

Current address: Department of Geology, University of Kansas, 1475 Jayhawk Blvd., Room 120, Lawrence, Kansas, 66045-7613, USA. Keywords: Falcarius utahensis, Cedar Mountain Formation, vertebrate paleontology, rare earth element, bone fossilization ABSTRACT The Crystal Geyser Dinosaur Quarry contains a large monospecific accumulation of bones from a basal therizinosaur, Falcarius utahensis. The quarry is located approximately 16 km south of Green River, Utah, at the base of the early Cretaceous (Barremian) Yellow Cat Member of the Cedar Mountain Formation. Fossil bones in the quarry occur in three units that have distinct taphonomic, lithologic, and geochemical characteristics. Rare earth element compositions of fossils suggest that bones from each unit were drawn from different reservoirs or sources having distinctly different compositions, and fossils were not reworked between units. Compositions of bones differ greatly within Units 1 and 2, even within the same 1-m2 quarry grid. These chemical differences and taphonomic characteristics, such as current orientation, hydraulic sorting, and occasional extensive abrasion, suggest that bones from these two units are allochthonous and were fossilized at other localities, possibly over an area of several kilometers, and were then eroded, transported, and concentrated in a spring-influenced fluvial environment. Bones in Unit 3 have very similar rare earth element signatures, suggesting that they were probably fossilized in situ at a separate time from bones in Units 1 and 2.
