Principal component analysis of the data suggests that the smaller footprints from the Valtos Sandstone and Kilmaluag formations are indistinguishable from the footprints of the Sundance Formation. The single footprint from the Lealt Shale Formation is similar to the larger footprints from the Valtos Sandstone Formation. The footprints from the Duntulm and Gypsum Springs formations form distinct groupings from all other footprints. Four different groupings of dinosaur footprints can be recognized from the principal component analysis that may represent at least four different types of dinosaur. -

Records from the Aalenian–Bajocian of Patagonia (Argentina): an Overview

FERNÁNDEZ † & MARIANELLA TALEVI‡ ∗ División Palaeontología Vertebrados, Museo de La Plata, Paseo del Bosque s/n, 1900 La Plata, Argentina. CONICET ‡Instituto de Investigación en Paleobiología y Geología, Universidad Nacional de Río Negro, 8332 General Roca, Río Negro, Argentina. CONICET (Received 12 September 2012; accepted 11 January 2013) Abstract – The oldest ophthalmosaurian records worldwide have been recovered from the Aalenian– Bajocian boundary of the Neuquén Basin in Central-West Argentina (Mendoza and Neuquén provinces). Although scarce, they document a poorly known period in the evolutionary history of parvipelvian ichthyosaurs. In this contribution we present updated information on these fossils, including a phylogenetic analysis, and a redescription of ‘Stenopterygius grandis’ Cabrera, 1939. Patagonian ichthyosaur occurrences indicate that during the Bajocian the Neuquén Basin palaeogulf, on the southern margins of the Palaeopacific Ocean, was inhabited by at least three morphologically discrete taxa: the slender Stenopterygius cayi, robust ophthalmosaurian Mollesaurus periallus and another indeterminate ichthyosaurian. Rib bone tissue structure indicates that rib cages of Bajocian ichthyosaurs included forms with dense rib microstructure (Mollesaurus) and forms with an ‘osteoporotic-like’ pattern (Stenopterygius cayi). Keywords: Mollesaurus,‘Stenopterygius grandis’, Middle Jurassic, Neuquén Basin, Argentina. 1. Introduction all Callovian and post-Callovian ichthyosaurs, two different Early Jurassic taxa have been proposed as Ichthyosaurs were one of the main predators in the ophthalmosaurian sister taxa: Stenopterygius (Maisch oceans all over the world during most of the Mesozoic & Matzke, 2000; Sander, 2000; Druckenmiller & (Massare, 1987). -

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. -

Email: [email protected] Manuscriptreceived:2June2014,accepted:6January2015 Abstract Stable oxygen isotope values of inoceramid marine bivalve shells recovered from Bentiaba, Angola, are utilised as a proxy for paleotemperatures during the Late Cretaceous development of the African margin of the South Atlantic Ocean. The d18O values derived from inoceramids show a long-term increase from –3.2‰ in the Late Turonian to values between –0.8 and –1.8‰ in the Late Campanian. Assuming a constant oceanic d18Ovalue,an∼2‰ increase may reflect cooling of the shallow marine environment at Bentiaba by approximately 10°. Bentiaba values are offset by about +1‰ from published records for bathyal Inoceramus at Walvis Ridge. This offset in d18O values suggests a temperature difference of ∼5° between coastal and deeper water offshore Angola. -

Preliminary Report on Ichthyopterygian Elements from the Early Triassic (Spathian) of Spitsbergen
NORWEGIAN JOURNAL OF GEOLOGY Vol 98 Nr. 2 https://dx.doi.org/10.17850/njg98-2-07 Preliminary report on ichthyopterygian elements from the Early Triassic (Spathian) of Spitsbergen Christina Pokriefke Ekeheien1, Lene Liebe Delsett1, Aubrey Jane Roberts2 & Jørn Harald Hurum1 1Natural History Museum, University of Oslo, Pb.1172 Blindern, N–0318 Oslo, Norway. 2Natural History Museum, London, United Kingdom. E-mail corresponding author (Lene Liebe Delsett): [email protected] Jaw elements of Omphalosaurus sp. are described from the Early Triassic (Spathian) of Marmierfjellet, Spitsbergen. The elements are from the Grippia and the Lower Saurian niveaus in the Vendomdalen Member of the Vikinghøgda Formation. In the Grippia niveau a bonebed was excavated in 2014–15 and a large number of ichthyopterygian elements were recovered. Together with the omphalosaurian jaw elements a collection of large vertebral centra were recognized as different from the smaller Grippia centra and more than 200 large vertebral centra are referred to Ichthyopterygia indet. and tentatively assigned to regions of the vertebral column. We refrain from further assignment due to the systematic position and the difficulty of defining criteria for recognizing postcranial elements of Omphalosaurus.
