2017-12-14 DP Platéosaure Et 10 Ans Galerie Des Dinosaures EN R “Ben the Plateosaurus” joins the Dinosaur Gallery on its tenth anniversary from 15 December 2017 • “Ben the Plateosaurus” joins the Dinosaur Gallery to mark its tenth anniversary. • It’s party time: Dino Family Day this Sunday 17/12/2017 • December 2017: the dinosaurs go into town! An event made possible thanks to various partners • A word from the Swiss Embassy in Belgium • Photo of Stan; the T. rex in the Dinosaur Gallery Press pack December 2017 Ben the Plateosaurus and the 10 th anniversary of the Dinosaur Gallery www.sciencesnaturelles.be Press release: “Ben the Plateosaurus” joins the Dinosaur Gallery to mark its tenth anniversary. With a floor area of 3000 m 2, our Dinosaur Gallery , which opened in 2007, is the largest room in Europe entirely devoted to the dinosaurs . It led to our Natural Sciences Museum being classed as one of the “world’s ten best dinosaur museums” by CNN in 2015. The new exhibition space, inaugurated exactly 10 years ago , has since welcomed over 3.2 million visitors. These ten years of success have motivated us constantly to increase our offer to our enthusiastic, knowledgeable and demanding public. To mark the anniversary, Ben the Plateosaurus, an exceptional fossil 210 million years old, discovered in Switzerland, will join the iguanodons, T. rex , Triceratops and other dinosaurs in our Gallery. Ben is exceptional because: o Our plateosaurus is an almost complete, authentic fossilised skeleton (at 80% complete?) . o It can, therefore, be exhibited without a glass case (but not without protection…), in a natural, attractive pose. o At 210 million years old, it is one of the very first large dinosaurs to inhabit the Earth . Before it, dinosaurs were no bigger than 1.5 m. Close to the origin of sauropods such as Diplodocus , it was also one of the first “long-necked” dinosaurs. We would like to take the opportunity to thank our partners, artists and Museum staff and above all the many crowdfunding donors (over 550!) who have enthusiastically helped to finance Ben’s installation. About Ben Press pack December 2017 Ben the Plateosaurus and the 10 th anniversary of the Dinosaur Gallery www.sciencesnaturelles.be Ben the Plateosaurus in figures 1 authentic fossilised skeleton (put together from two individual animals) No glass case for a true face to face experience! Approximately 6.5 m long, making it one of the first large dinosaurs 200 fossilised bones, prepared and assembled in the Museum by the Plateoteam 210 million years old …! Ben is an authentic skeleton from the village of Frick in Switzerland. It was named after the palaeontologist who discovered it – Ben Pabst. The Plateoteam, a team of palaeontologists and technicians at the Museum of Natural Sciences, worked for 18 months to extract the bones and reconstruct the skeleton. It is now on permanent display at the Museum of Natural Sciences in Brussels, to mark the 10th anniversary of the opening of the Dinosaur Gallery. Measuring around 6.50 m in length and living some 210 million years ago, it is one of the largest dinosaurs of the Triassic period (its predecessors did not exceed 1.5 m). Above all, it is also one of the first “long-necked” dinosaurs. It belonged to the line of prosauropods, precursors of the sauropods such as Diplodocus . It had a long tail and a relatively long neck. Its size enabled it to feed on a wide variety of plants (though it probably ate anything it came across: insects, small animals, carrion, etc.). As a biped, Plateosaurus could rear up when required and thus reach the leaves on higher branches. It lived in a herd and used its powerful front claws to defend itself. Where does our fossilised specimen come from? Our plateosaurus comes from Frick quarry in Switzerland. This specimen has not so far been found anywhere other than in Europe: to date examples have only been found in Germany, Switzerland and France. Frick quarry is an exceptional location for finds of dinosaurs from the end of the Triassic period (around 210 million years ago). More than 30 Plateosaurus skeletons in various stages of completeness have been unearthed there in the last 40 years. While the majority of initial discoveries were accidental, various systematic excavations have been planned and conducted since 1976. The rich finds made recently have given us a better understanding of the anatomy and way of life of the Plateosaurus . After Bernissart (near Mons in Belgium, site of discovery of the Iguanodons in 1878), Frick is one of the richest locations in Europe in terms of the concentration of articulated dinosaur skeletons. These dinosaurs were probably engulfed in the mud of the huge marshlands that covered the region at the end of the Triassic period. Press pack December 2017 Ben the Plateosaurus and the 10 th anniversary of the Dinosaur Gallery www.sciencesnaturelles.be The Frick Dinosaur Museum offered our Institute the permanent loan of a Plateosaurus specimen. Too many unprepared fossils are accumulating in their storerooms and they cannot prepare them all. Consequently, they prefer to send them abroad: the host institution must prepare the skeleton that is on loan and then display it in its exhibition room. “Ben preparing in the wings” November 2017 © Th.Hubin @Museum Press pack December 2017 Ben the Plateosaurus and the 10 th anniversary of the Dinosaur Gallery www.sciencesnaturelles.be About the Dinosaur Gallery © Th.Hubin@Muséum “The Dinosaur Gallery” The Dinosaur Gallery in figures 39 different species (= types) of dinosaur on display, including real specimens and casts.

    v^ Official Journal of the Biology Unit of the American Topical Association 10 Vol. 40(4) DINOSAURS ON STAMPS by Michael K. Brett-Surman Ph.D. Dinosaurs are the most popular animals of all time, and the most misunderstood. Dinosaurs did not fly in the air and did not live in the oceans, nor on lake bottoms. Not all large "prehistoric monsters" are dinosaurs. The most famous NON-dinosaurs are plesiosaurs, moso- saurs, pelycosaurs, pterodactyls and ichthyosaurs. Any name ending in 'saurus' is not automatically a dinosaur, for' example, Mastodonto- saurus is neither a mastodon nor a dinosaur - it is an amphibian! Dinosaurs are defined by a combination of skeletal features that cannot readily be seen when the animal is fully restored in a flesh reconstruction. Because of the confusion, this compilation is offered as a checklist for the collector. This topical list compiles all the dinosaurs on stamps where the actual bones are pictured or whole restorations are used. It excludes footprints (as used in the Lesotho stamps), cartoons (as in the 1984 issue from Gambia), silhouettes (Ascension Island # 305) and unoffi- cial issues such as the famous Sinclair Dinosaur stamps. The name "Brontosaurus", which appears on many stamps, is used with quotation marks to denote it as a popular name in contrast to its correct scientific name, Apatosaurus. For those interested in a detailed encyclopedic work about all fossils on stamps, the reader is referred to the forthcoming book, 'Paleontology - a Guide to the Postal Materials Depicting Prehistoric Lifeforms' by Fran Adams et. al. The best book currently in print is a book titled 'Dinosaur Stamps of the World' by Baldwin & Halstead.

    VoL. 6, 1920 PALAEONTOLOGY: OSBORN AND MOOK IS RECONSTRUCTION OF THE SKELETON OF THE SAUROPOD DINOSAUR CAMARASA URUS COPE (MOROSA URUS MARSH) By HENRY FAIRFIELD OSBORN AND CHARLES CRAIG MOOK AMERICAN MusEUM or NATURAL HISTORY, NEW YORK CITY Read before the Academy, November 11, 1919 The principles of modern research in vertebrate palaeontology are illustrated in the fifteen years' work resulting in the restoration of the massive sauropod dinosaur known as Camarasaurus, the "chambered saurian.." The animal was found near Canyon City, Colorado, in March, 1877. The first bones were described by Cope, August 23, 1877. The first at- tempted restoration was by Ryder, December 21, 1877. The bones analyzed by this research were found probably to belong to six individuals of Camarasaurus mingled with the remains of some carnivorous dinosaurs, all from the summit of the Morrison formation, now regarded as of Jurassic- Cretaceous age. In these two quarries Cope named nine new genera and fourteen new species of dinosaurs, none of which have found their way into. palaeontologic literature, excepting Camarasaurus. Out of these twenty-three names we unravel three genera, namely: One species of Camarasaurus, identical with Morosaurus Marsh. One species of Amphicaclias, close to Diplodocus Marsh. One species of Epanterias, close to Allosaurus Marsh. The working out of the Camarasaurus skeleton results in both the artica ulated restoration and the restoration of the musculature. The following are the principal characters: The neck is very flexible; anterior vertebrae of the back also freely movable; the division between the latter and the relatively rigid posterior dorsals is sharp.

  • The Anatomy and Phylogenetic Relationships of Antetonitrus Ingenipes (Sauropodiformes, Dinosauria): Implications for the Origins of Sauropoda
    THE ANATOMY AND PHYLOGENETIC RELATIONSHIPS OF ANTETONITRUS INGENIPES (SAUROPODIFORMES, DINOSAURIA): IMPLICATIONS FOR THE ORIGINS OF SAUROPODA Blair McPhee A dissertation submitted to the Faculty of Science, University of the Witwatersrand, in partial fulfilment of the requirements for the degree of Master of Science. Johannesburg, 2013 i ii ABSTRACT A thorough description and cladistic analysis of the Antetonitrus ingenipes type material sheds further light on the stepwise acquisition of sauropodan traits just prior to the Triassic/Jurassic boundary. Although the forelimb of Antetonitrus and other closely related sauropododomorph taxa retains the plesiomorphic morphology typical of a mobile grasping structure, the changes in the weight-bearing dynamics of both the musculature and the architecture of the hindlimb document the progressive shift towards a sauropodan form of graviportal locomotion. Nonetheless, the presence of hypertrophied muscle attachment sites in Antetonitrus suggests the retention of an intermediary form of facultative bipedality. The term Sauropodiformes is adopted here and given a novel definition intended to capture those transitional sauropodomorph taxa occupying a contiguous position on the pectinate line towards Sauropoda. The early record of sauropod diversification and evolution is re- examined in light of the paraphyletic consensus that has emerged regarding the ‘Prosauropoda’ in recent years. iii ACKNOWLEDGEMENTS First, I would like to express sincere gratitude to Adam Yates for providing me with the opportunity to do ‘real’ palaeontology, and also for gladly sharing his considerable knowledge on sauropodomorph osteology and phylogenetics. This project would not have been possible without the continued (and continual) support (both emotionally and financially) of my parents, Alf and Glenda McPhee – Thank you.

  • Re-Description of the Sauropod Dinosaur Amanzia (“Ornithopsis
    Schwarz et al. Swiss J Geosci (2020) 113:2 https://doi.org/10.1186/s00015-020-00355-5 Swiss Journal of Geosciences ORIGINAL PAPER Open Access Re-description of the sauropod dinosaur Amanzia (“Ornithopsis/Cetiosauriscus”) greppini n. gen. and other vertebrate remains from the Kimmeridgian (Late Jurassic) Reuchenette Formation of Moutier, Switzerland Daniela Schwarz1* , Philip D. Mannion2 , Oliver Wings3 and Christian A. Meyer4 Abstract Dinosaur remains were discovered in the 1860’s in the Kimmeridgian (Late Jurassic) Reuchenette Formation of Moutier, northwestern Switzerland. In the 1920’s, these were identifed as a new species of sauropod, Ornithopsis greppini, before being reclassifed as a species of Cetiosauriscus (C. greppini), otherwise known from the type species (C. stewarti) from the late Middle Jurassic (Callovian) of the UK. The syntype of “C. greppini” consists of skeletal elements from all body regions, and at least four individuals of diferent sizes can be distinguished. Here we fully re-describe this material, and re-evaluate its taxonomy and systematic placement. The Moutier locality also yielded a theropod tooth, and fragmen- tary cranial and vertebral remains of a crocodylomorph, also re-described here. “C.” greppini is a small-sized (not more than 10 m long) non-neosauropod eusauropod. Cetiosauriscus stewarti and “C.” greppini difer from each other in: (1) size; (2) the neural spine morphology and diapophyseal laminae of the anterior caudal vertebrae; (3) the length-to-height proportion in the middle caudal vertebrae; (4) the presence or absence of ridges and crests on the middle caudal cen- tra; and (5) the shape and proportions of the coracoid, humerus, and femur.

  • MANUS, SACRUM, and CAUDALS of by HENRY FAIRFIELD
    Article XIV.- MANUS, SACRUM, AND CAUDALS OF SAUROPODA. By HENRY FAIRFIELD OSBORN. DINOSAUR CONTRIBUTION No. 7. The following notes on new materials from the Bone Cabin Quarry in the American Museum were prepared for the U. S. Geological Survey monograph on the Sauropoda, and partly correct previous papers. I am indebted to Mr. Walter Granger, who has charge of the Bone Cabin collection, for several valuable observations, and to Director Charles D. Walcott of the Survey for permission to publish in this form. I. STRUCTURE OF THE MANUS. - My previous figures and descriptions of the manus are all incorrect. The single Claw on Digit I. - From two specimens in the Field Columbian Museum, from the correctly described (Hatcher) and figured manus of Brontosaurus in the Carnegie Museum, and from eight specimens in the American Museum, it appears as if in the manus of Diplodocus, Brontosaurus, and possibly of Morosaurus, there was but one claw, and that a small one, on the pollex. Two specimens only in the American Museum (Nos. 276, 332) exhibit two claws, but both are of very doubtful association. The oblique direction or partial retroversion of this pollex claw (D. I.) is a feature to which Dr. E. S. Riggs especially di- rected my attention; the inferior facet of Mtc. I, and the two facets of the proximal phalanx are bevelled in such a manner as to give an oblique outward and slightly backward angle to the terminal or claw phalanx; the retroversion, however, is much less marked than in the manus of the Theropoda. Phalanges reduced.

  • A New Diplodocoid Sauropod Dinosaur from the Upper Jurassic Morrison Formation of Montana, USA
    A new diplodocoid sauropod dinosaur from the Upper Jurassic Morrison Formation of Montana, USA JERALD D. HARRIS and PETER DODSON Harris, J.D. and Dodson, P. 2004. A new diplodocoid sauropod dinosaur from the Upper Jurassic Morrison Formation of Montana, USA. Acta Palaeontologica Polonica 49 (2): 197–210. A partial skeleton of a new sauropod dinosaur from the Upper Jurassic Morrison Formation (?Tithonian) of Montana is described. Suuwassea emilieae gen. et sp. nov. is diagnosed by numerous cranial, axial, and appendicular autapo− morphies. The holotype consists of a premaxilla, partial maxilla, quadrate, braincase with partial skull roof, several partial and complete cranial and middle cervical, cranial dorsal, and caudal vertebrae, ribs, complete scapulocoracoid, humerus, partial tibia, complete fibula, calcaneus, and partial pes. It displays numerous synapomorphies of the Diplodocoidea, in− cluding characters of both the Diplodocidae (Apatosaurus +(Diplodocus + Barosaurus)) and Dicraeosauridae (Dicraeo− saurus + Amargasaurus). Preliminary phylogenetic analysis indicates that Suuwassea is a diplodocoid more derived than rebbachisaurids but in a trichotomy with both the Diplodocidae and Dicraeosauridae. Suuwassea represents the first well−supported, North American, non−diplodocid representative of the Diplodocoidea and provides new insight into the origins of both the Diplodocidae and Dicraeosauridae.
