Structural Interpretation of the Cherokee Arch, South
STRUCTURAL INTERPRETATION OF THE CHEROKEE ARCH, SOUTH CENTRAL WYOMING, USING 3-D SEISMIC DATA AND WELL LOGS by Joel Ysaccis B. ABSTRACT The purpose of this study is to use 3-D seismic data and well logs to map the structural evolution of the Cherokee Arch, a major east-west trending basement high along the Colorado-Wyoming state line. The Cherokee Arch lies along the Cheyenne lineament, a major discontinuity or suture zone in the basement. Recurrent, oblique-slip offset is interpreted to have occurred along faults that make up the arch. Gas fields along the Cherokee Arch produce from structural and structural-stratigraphic traps, mainly in Cretaceous rocks. Some of these fields, like the South Baggs – West Side Canal fields, have gas production from multiple pays. The tectonic evolution of the Cherokee Arch has not been previously studied in detail. About 315 mi2 (815 km2) of 3-D seismic data were analyzed in this study to better understand the kinematic evolution of the area. The interpretation involved mapping the Madison, Shinarump, Above Frontier, Mancos, Almond, Lance/Fox Hills and Fort Union horizons, as well as defining fault geometries. Structure maps on these horizons show the general tendency of the structure to dip towards the west. The Cherokee Arch is an asymmetrical anticline in the hanging wall, which is mainly transected by a south-dipping series of east-west striking thrust faults. The interpreted thrust faults generally terminate within the Mancos to Above Frontier interval, and their vertical offset increases in magnitude down to the basement. Post-Mancos iii intervals are dominated by near-vertical faults with apparent normal offset. -

Estesia Mongoliensis (Squamata: Anguimorpha) and the Evolution of Venom Grooves in Lizards
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by American Museum of Natural History Scientific Publications AMERICAN MUSEUM NOVITATES Number 3767, 31 pp. January 25, 2013 New materials of Estesia mongoliensis (Squamata: Anguimorpha) and the evolution of venom grooves in lizards HONG-YU YI1,2 AND MARK A. NORELL1,2 ABSTRACT New specimens of the fossil lizard Estesia mongoliensis are described from the Upper Cre- taceous of Mongolia. Phylogenetic analysis of 86 anguimorph taxa coded with 435 morphologi- cal characters and four genes confirms the placement of Estesia mongoliensis in a monophyletic Monstersauria. Extant monstersaurs, the genus Heloderma, are the only extant lizards bearing venom-transmitting teeth with a deep venom grove in the rostral carina. Compared to the crown group, stem monstersaurs are morphologically more variable in venom-delivery appa- ratus. This study has found that Estesia mongoliensis has two shallow grooves in the rostral and caudal carinae of its dentary teeth, demonstrating a primary venom-delivery apparatus. A sum- mary of venom-delivering tooth specialization in the Anguimorpha is provided, and related morphological characters are optimized on the strict consensus tree resulting from the com- bined morphological and molecular analysis of anguimorph phylogeny. The phylogeny supports a single origination of venom grooves in the Monstersauria, and indicates that grooved teeth are currently the only reliable venom-delivery apparatus to be recognized in fossil lizards. Key Words: Estesia mongoliensis, Monstersauria, venom groove, Anguimorpha INTRODUCTION Estesia mongoliensis is the oldest fossil squamate with dental grooves comparable to venom grooves in extant species. -

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. -
Theropod Teeth from the Upper Maastrichtian Hell Creek Formation “Sue” Quarry: New Morphotypes and Faunal Comparisons
Theropod teeth from the upper Maastrichtian Hell Creek Formation “Sue” Quarry: New morphotypes and faunal comparisons TERRY A. GATES, LINDSAY E. ZANNO, and PETER J. MAKOVICKY Gates, T.A., Zanno, L.E., and Makovicky, P.J. 2015. Theropod teeth from the upper Maastrichtian Hell Creek Formation “Sue” Quarry: New morphotypes and faunal comparisons. Acta Palaeontologica Polonica 60 (1): 131–139. Isolated teeth from vertebrate microfossil localities often provide unique information on the biodiversity of ancient ecosystems that might otherwise remain unrecognized. Microfossil sampling is a particularly valuable tool for doc- umenting taxa that are poorly represented in macrofossil surveys due to small body size, fragile skeletal structure, or relatively low ecosystem abundance. Because biodiversity patterns in the late Maastrichtian of North American are the primary data for a broad array of studies regarding non-avian dinosaur extinction in the terminal Cretaceous, intensive sampling on multiple scales is critical to understanding the nature of this event. We address theropod biodiversity in the Maastrichtian by examining teeth collected from the Hell Creek Formation locality that yielded FMNH PR 2081 (the Tyrannosaurus rex specimen “Sue”). Eight morphotypes (three previously undocumented) are identified in the sample, representing Tyrannosauridae, Dromaeosauridae, Troodontidae, and Avialae. Noticeably absent are teeth attributed to the morphotypes Richardoestesia and Paronychodon. Morphometric comparison to dromaeosaurid teeth from multiple Hell Creek and Lance formations microsites reveals two unique dromaeosaurid morphotypes bearing finer distal denticles than present on teeth of similar size, and also differences in crown shape in at least one of these. These findings suggest more dromaeosaurid taxa, and a higher Maastrichtian biodiversity, than previously appreciated. -

Diapsid Phylogeny and the Origin and Early Evolution of Squamates by Tiago Rodrigues Simões A thesis submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in SYSTEMATICS AND EVOLUTION Department of Biological Sciences University of Alberta © Tiago Rodrigues Simões, 2018 ABSTRACT Squamate reptiles comprise over 10,000 living species and hundreds of fossil species of lizards, snakes and amphisbaenians, with their origins dating back at least as far back as the Middle Jurassic. Despite this enormous diversity and a long evolutionary history, numerous fundamental questions remain to be answered regarding the early evolution and origin of this major clade of tetrapods. Such long-standing issues include identifying the oldest fossil squamate, when exactly did squamates originate, and why morphological and molecular analyses of squamate evolution have strong disagreements on fundamental aspects of the squamate tree of life. Additionally, despite much debate, there is no existing consensus over the composition of the Lepidosauromorpha (the clade that includes squamates and their sister taxon, the Rhynchocephalia), making the squamate origin problem part of a broader and more complex reptile phylogeny issue. In this thesis, I provide a series of taxonomic, phylogenetic, biogeographic and morpho-functional contributions to shed light on these problems. I describe a new taxon that overwhelms previous hypothesis of iguanian biogeography and evolution in Gondwana (Gueragama sulamericana). I re-describe and assess the functional morphology of some of the oldest known articulated lizards in the world (Eichstaettisaurus schroederi and Ardeosaurus digitatellus), providing clues to the ancestry of geckoes, and the early evolution of their scansorial behaviour. -
