We conclude that these fossil remains represent a bipedal heterodontosaurid but lack diagnostic characters to identify them at the species level, although they probably represent remains of Manidens condorensis, known from the same locality. Histological features suggest a subadult ontogenetic stage for the individual. A cluster analysis based on pedal measurements identifies similarities of this specimen with heterodontosaurid taxa and the inclusion of the new material in a phylogenetic analysis with expanded character sampling on pedal remains confirms the described specimen as a heterodontosaurid. Finally, uncommon features of the digits (length proportions among nonungual phalanges of digit III, and claw features) are also quantitatively compared to several ornithischians, theropods, and birds, suggesting that this may represent a bipedal cursorial heterodontosaurid with gracile and grasping feet and long digits.

    Petrologische und Geochemische Untersuchungen an ultramafischen und mafischen Gesteinen der Shackleton Range, Ost-Antarktis Zeugen des Zusammenschlusses Gondwanas und letzte Relikte eines einstigen Ozeans? Der Naturwissenschaftlichen Fakultät/ Dem Fachbereich Geographie und Geowissenschaften der Friedrich-Alexander-Universität Erlangen-Nürnberg zur Erlangung des Doktorgrades Dr. rer. Nat. vorgelegt von Tanja Romer aus Illertissen i Als Dissertation genehmigt von der Naturwissenschaftlichen Fakultät/ vom Fachbereich Geographie und Geowissenschaften der Friedrich-Alexander-Universität Erlangen-Nürnberg Tag der mündlichen Prüfung: 01.06.2017 Vorsitzende/r des Promotionsorgans: Prof. Dr. Georg Kreimer Gutachter/in: Prof. Dr. Esther Schmädicke Prof. Dr. Reiner Klemd ii Zusammenfassung Im östlichen Teil der Antarktis liegt die Shackleton Range. Es handelt sich hierbei um ein Kollisionsorogen, das nach heutigen Erkenntnissen der panafrikanischen Orogenese zugeordnet wird. Hinweise darauf finden sich im nördlichen Bereich (z.B. Haskard Highlands) der Shackleton Range. Hier treten granatführende, ultramafische Gesteine als Linsen, eingeschlossen in hochgradig metamorphen Gneisen auf. Die Linsen setzen sich hauptsächlich aus granat- und/oder spinell-führenden Pyroxeniten und untergeordnet auch Peridotiten zusammen. Die nähere Umgebung der Linsen wird vor allem durch Amphibolite dominiert. Die Pyroxenite enthalten teilweise eine Verwachsung von Granat und Olivin und sind damit ein eindeutiger Indikator für eine eklogitfazielle Metamorphose in diesem Bereich. Weiterhin zeugen sie als ultramafische Gesteine von einer möglichen Suturzone. In dieser Forschungsarbeit konnte mittels Mikrosondenanalytik an Granat, Ortho- und Klinopyroxen, Spinell, Olivin und Amphibol für die ultramafischen Gesteine ein Teil des im Uhrzeigersinn verlaufenden P-T-Pfads rekonstruiert werden. Thermobarometrische Berechnungen ergaben maximale Metamorphosetemperaturen von 800 bis 850 °C. Die maximal erreichten Drücke dürften zwischen 20 bis 23 kbar gelegen haben.

  • A Phylogenetic Analysis of the Basal Ornithischia (Reptilia, Dinosauria)
    A PHYLOGENETIC ANALYSIS OF THE BASAL ORNITHISCHIA (REPTILIA, DINOSAURIA) Marc Richard Spencer A Thesis Submitted to the Graduate College of Bowling Green State University in partial fulfillment of the requirements of the degree of MASTER OF SCIENCE December 2007 Committee: Margaret M. Yacobucci, Advisor Don C. Steinker Daniel M. Pavuk © 2007 Marc Richard Spencer All Rights Reserved iii ABSTRACT Margaret M. Yacobucci, Advisor The placement of Lesothosaurus diagnosticus and the Heterodontosauridae within the Ornithischia has been problematic. Historically, Lesothosaurus has been regarded as a basal ornithischian dinosaur, the sister taxon to the Genasauria. Recent phylogenetic analyses, however, have placed Lesothosaurus as a more derived ornithischian within the Genasauria. The Fabrosauridae, of which Lesothosaurus was considered a member, has never been phylogenetically corroborated and has been considered a paraphyletic assemblage. Prior to recent phylogenetic analyses, the problematic Heterodontosauridae was placed within the Ornithopoda as the sister taxon to the Euornithopoda. The heterodontosaurids have also been considered as the basal member of the Cerapoda (Ornithopoda + Marginocephalia), the sister taxon to the Marginocephalia, and as the sister taxon to the Genasauria. To reevaluate the placement of these taxa, along with other basal ornithischians and more derived subclades, a phylogenetic analysis of 19 taxonomic units, including two outgroup taxa, was performed. Analysis of 97 characters and their associated character states culled, modified, and/or rescored from published literature based on published descriptions, produced four most parsimonious trees. Consistency and retention indices were calculated and a bootstrap analysis was performed to determine the relative support for the resultant phylogeny. The Ornithischia was recovered with Pisanosaurus as its basalmost member.

  • Preservation of Pliocene Age Surfaces Beneath the WAIS: Insights from Emergent Nunataks in the Ohio Range
    Preservation of Pliocene age surfaces beneath the WAIS: Insights from emergent nunataks in the Ohio Range Robert P. Ackert Jr., Sujoy Mukhopadhyay Department of Earth and Planetary Science, Harvard University, Cambridge, MA 02138 Harold W. Borns, Aaron E. Putnam Climate Change Institute, University of Maine, Orono, ME, 04469 The granitic bedrock forming the Ohio Range Escarpment and adjacent Bennett and Tuning Nunataks is typically cavernously weathered with pits ranging from a few cm to > 100 cm. The rock remaining between pits often forms delicate structures only several cm thick (tafoni). Cosmogenic 21Ne and 10Be concentrations indicate that the weathered bedrock surfaces are at least 4 million years old with average erosion rates of 15-35 cm /Ma on surfaces between pits. However, exposure ages of erratics on the escarpment 125 m above the present WAIS surface (~1500 m) indicates that the nunataks were buried by the WAIS 10,000 years ago (Ackert et al., 2007). Ice temperatures at these relatively shallow depths would be well below freezing, and the WAIS remained cold-based. Consequently, glacial erosion has been minimal, generally restricted to breakage of only the most delicate weathering structures. Tuning Nunatak is located in an area with higher ice velocities as indicated by crevasses and steeper surface slopes. There, limited quarrying of horizontally jointed bedrock has locally removed up to 1 m of rock and produced a few glacial scratches. Paired 21Ne and 10Be data indicate that the duration of ice cover was limited. Samples of bedrock from three nunataks fall within the zone of simple exposure on 21Ne/10Be vs.10Be plots indicating that unsupported decay of 10Be (half life = 1.5 Myr) was minimal, and no recent burial event exceeded 50, 000 years.

  • Alaska Range
    Alaska Range Introduction The heavily glacierized Alaska Range consists of a number of adjacent and discrete mountain ranges that extend in an arc more than 750 km long (figs. 1, 381). From east to west, named ranges include the Nutzotin, Mentas- ta, Amphitheater, Clearwater, Tokosha, Kichatna, Teocalli, Tordrillo, Terra Cotta, and Revelation Mountains. This arcuate mountain massif spans the area from the White River, just east of the Canadian Border, to Merrill Pass on the western side of Cook Inlet southwest of Anchorage. Many of the indi- Figure 381.—Index map of vidual ranges support glaciers.

Roland', Martin Olcsch2 and Wolfgang Schubert' Summary: During the GEISHA expedition (Geologische Expedition in die during apre-Ross metarnorphic event or orogeny. The Ross Orogeny at about Shackleton Range 1987/88), the Pioneers Escarpment was visited and sampled 500 Ma probably just led to the weak greensehrst facies overprint that is evi­ extensively for the first time. Most of the rock types eneountered represent dent in the rocks of the Pioneers Group. amphibolite faeies metamorphics, but evidence for granulite facies conditions was found in cores of garnet. These conelitions must have been at least partly Finally, sedimentation resumed in the area of the present Shacklcton Range, or reached during the peak of metamorphism. at least in the eastern part of the Pioneers Escarpment, probably when detritus from erosion of the basement (Read Group and Pioneers Group) was deposi­ For the Pioneers Escarpment a varicolored succession of sedimentary anel bi­ ted, forming sandstones and greywackes of possibly Jurassie age.
