11Th EAVP Meeting – Villers-Sur-Mer France 11Th – 15 Th June 2013 11th EAVP Meeting – Villers-sur-Mer France 11th – 15 th June 2013 « Accéder à la science, c’est, spirituellement rajeunir ; c’est accepter une mutation brusque qui doit contredire un passé. » Gaston Bachelard, 1938. Avec la création du Paléospace, Musée de France, il y a deux ans, la ville de Villers-sur-Mer en partenariat avec la Communauté de Communes Cœur Côte Fleurie concrétisait un projet qui lui tenait à cœur depuis plus de 18 ans et qui était sous-jacent depuis le 20e siècle, avec la sauvegarde et la conservation de collections locales et privées de paléontologie. Collectionneurs, amateurs de fossiles puis scientifiques, ont enrichi ce fonds grâce à leurs dons et leurs connaissances et ce, avec le même objectif : comprendre… La construction d’un musée n’est pas une finalité en soi. La vocation du Paléospace est d’une part de faire vivre les collections, les porter à la connaissance du plus grand nombre par le biais des expositions permanentes et temporaires, d’actions d’éducation, de l’ouverture des réserves, de la diffusion culturelle et scientifique et d’autre part d’apporter nos compétences et notre soutien aux progrès des connaissances et de la recherche. C’est pourquoi nous nous réjouissons d’offrir ce moment privilégié pour le propos scientifique et d’accueillir le 11e congrès de l’European Association of Vertebrate Palaeontologists, permettant de mettre en lumière les travaux des paléontologues. Nous espérons que le cadre de Villers-sur-Mer sera idéal pour ce congrès, que nous souhaitons convivial et riche en échanges. Nous pourrons alors nous féliciter d’avoir contribué à notre mesure, aux efforts de la recherche scientifique. Bienvenue à Villers-sur-Mer, nous vous souhaitons un excellent congrès !

  • Biostratigraphy and Paleoecology of Continental Tertiary Vertebrate Faunas in the Lower Rhine Embayment (NW-Germany)

Mors Naturhistoriska Riksmuseet/Swedish Museum of Natural History, Department of Palaeozoology, P.O. Box 50007, SE-104 05 Stockholm, Sweden; e-mail: [email protected] Manuscript received: October 2000; accepted: January 2002 ^ Abstract This paper discusses the faunal content, the mammal biostratigraphy, and the environmental ecology of three important con­ tinental Tertiary vertebrate faunas from the Lower Rhine Embayment. The sites investigated are Rott (MP 30, Late Oligocene), Hambach 6C (MN 5, Middle Miocene), Frechen and Hambach 11 (both MN 16, Late Pliocene). Comparative analysis of the entire faunas shows the assemblages to exhibit many conformities in their general composition, presumably re­ sulting from their preference for wet lowlands. It appears that very similar environmental conditions for vertebrates reoc- curred during at least 20 Ma although the sites are located in a tectonically active region with high subsidence rates. Differ­ ences in the faunal composition are partly due to local differences in the depositional environment of the sites: lake deposits at the margin of the embayment (Rott), coal swamp and estuarine conditions in the centre of the embayment (Hambach 6C), and flood plain environments with small rivulets (Frechen and Hambach 1 l).The composition of the faunal assemblages (di­ versity and taxonomy) also documents faunal turnovers with extinctions and immigrations (Oligocene/Miocene and post- Middle Miocene), as a result of changing climate conditions. Additional vertebrate faunal data were retrieved from two new assemblages collected from younger strata at the Hambach mine (Hambach 11C and 14).

  • Estimating the Evolutionary Rates in Mosasauroids and Plesiosaurs: Discussion of Niche Occupation in Late Cretaceous Seas
    Estimating the evolutionary rates in mosasauroids and plesiosaurs: discussion of niche occupation in Late Cretaceous seas Daniel Madzia1 and Andrea Cau2 1 Department of Evolutionary Paleobiology, Institute of Paleobiology, Polish Academy of Sciences, Warsaw, Poland 2 Independent, Parma, Italy ABSTRACT Observations of temporal overlap of niche occupation among Late Cretaceous marine amniotes suggest that the rise and diversification of mosasauroid squamates might have been influenced by competition with or disappearance of some plesiosaur taxa. We discuss that hypothesis through comparisons of the rates of morphological evolution of mosasauroids throughout their evolutionary history with those inferred for contemporary plesiosaur clades. We used expanded versions of two species- level phylogenetic datasets of both these groups, updated them with stratigraphic information, and analyzed using the Bayesian inference to estimate the rates of divergence for each clade. The oscillations in evolutionary rates of the mosasauroid and plesiosaur lineages that overlapped in time and space were then used as a baseline for discussion and comparisons of traits that can affect the shape of the niche structures of aquatic amniotes, such as tooth morphologies, body size, swimming abilities, metabolism, and reproduction. Only two groups of plesiosaurs are considered to be possible niche competitors of mosasauroids: the brachauchenine pliosaurids and the polycotylid leptocleidians. However, direct evidence for interactions between mosasauroids and plesiosaurs is scarce and limited only to large mosasauroids as the Submitted 31 July 2019 predators/scavengers and polycotylids as their prey. The first mosasauroids differed Accepted 18 March 2020 from contemporary plesiosaurs in certain aspects of all discussed traits and no evidence Published 13 April 2020 suggests that early representatives of Mosasauroidea diversified after competitions with Corresponding author plesiosaurs.

A framework of ichthyofaunal ecostrati- graphy of the Oligocene–Early Miocene strata of the Polish Outer Carpathian basin. Annales Societatis Geologorum Poloniae, 76: 1–111. Abstract: The paper presents the results of an analysis of ichthyofaunal variability throughout the section of the Menilite-Krosno Series (MKS) in the Outer Carpathians of Poland. The studied tanathocoenoses were formed at the bottom of a more than 2,000 m deep northern basin of the Tethys, being largely represented by the continental rise and bottoms of its narrow furrows, and – to a lesser degree – the continental slope and slopes of a submarine high. Lateral variability of statististically representative assemblages of tanathocoenoses hosted in thin, isochro- nous horizons is interpreted as a result of both local changes of ichthyocoenoses and the influence of post-mortem relocation of fishes that mainly dwelled the shelf and upper continental slope. Vertical variability, in turn, is considered as a resulting from changeable conditions of the ecological environment, the input and outflow of taxa whose evolution proceeded in the Indo-Pacific area, and the species extinction. Changeability of ichthyofauna within a ca.

A review of studies of sexual dimorphism in the vertebrate fossil record revealed methods that were selected for use in ceratopsids. Mountain goats, bison, and pronghorn were selected as exemplar taxa for a proof of principle study that tested the selected methods, and informed and guided the investigation of sexual dimorphism in dinosaurs. Skulls of these exemplar taxa were measured in museum collections, and methods of analysing morphological variation were tested for their ability to demonstrate sexual dimorphism in their horns and horncores.

COATES1 and DONALD L. J. QUICKE2 1 The Department of Organismal Biology and Anatomy, The University of Chicago, 1027 East 57th Street, Chicago, IL 60637-1508, USA ([email protected]; [email protected]) 2 Department of Biology, Imperial College at Silwood Park, Ascot, Berkshire SL57PY, UK and Department of Entomology, The Natural History Museum, Cromwell Road, London SW75BD, UK ([email protected]) (Received 29 November 2001; revised 28 August 2002; accepted 2 September 2002) ABSTRACT In an attempt to investigate differences between the most widely discussed hypotheses of early tetrapod relation- ships, we assembled a new data matrix including 90 taxa coded for 319 cranial and postcranial characters. We have incorporated, where possible, original observations of numerous taxa spread throughout the major tetrapod clades. A stem-based (total-group) definition of Tetrapoda is preferred over apomorphy- and node-based (crown-group) definitions. This definition is operational, since it is based on a formal character analysis. A PAUP* search using a recently implemented version of the parsimony ratchet method yields 64 shortest trees. Differ- ences between these trees concern: (1) the internal relationships of aı¨stopods, the three selected species of which form a trichotomy; (2) the internal relationships of embolomeres, with Archeria

    IJREISS Volume 2, Issue 8 (August 2012) ISSN: 2250-0588 FOSSIL MAMMALS (RHINOCEROTIDS, GIRAFFIDS, BOVIDS) FROM THE MIOCENE ROCKS OF DHOK BUN AMEER KHATOON, DISTRICT CHAKWAL, PUNJAB, PAKISTAN 1Khizar Samiullah* 1Muhammad Akhtar, 2Muhammad A. Khan and 3Abdul Ghaffar 1Zoology department, Quaid-e-Azam campus, Punjab University, Lahore, Punjab, Pakistan 2Zoology Department, GC University, Faisalabad, Punjab, Pakistan 3Department of Meteorology, COMSATS Institute of Information Technology (CIIT), Islamabad ABSTRACT Fossil site Dhok Bun Ameer Khatoon (32o 47' 26.4" N, 72° 55' 35.7" E) yielded a significant amount of mammalian assemblage including two families of even-toed fossil mammal (Giraffidae, and Bovidae) and one family of odd-toed (Rhinocerotidae) of the Late Miocene (Samiullah, 2011). This newly discovered site has well exposed Chinji and Nagri formation and has dated approximately 14.2-9.5 Ma. This age agrees with the divergence of different mammalian genera. Sedimentological evidence of the site supports that this is deposited in locustrine or fluvial environment, as Chinji formation is composed primarily of mud-stone while the Nagri formation is sand dominated. Palaeoenvironmental data indicates that Miocene climate of Pakistan was probably be monsoonal as there is now a days. Mostly the genera recovered from this site resemble with the overlying younger Dhok Pathan formation of the Siwaliks while the size variation in dentition is taxonomically important for vertebrate evolutionary point of view and this is the main reason to conduct this study at this specific site to add additional information in the field of Palaeontology. A detailed study of fossils mammals found in Miocene rocks exposed at Dhok Bun Ameer Khatoon was carried out.
