  • Late Triassic) Conodont and Ammonoid
    LATE CARNIAN (LATE TRIASSIC) CONODONT AND AMMONOID PALEONTOLOGY OF WRANGELLIA by Emily Kathryn Hopkin B.Sc., State University of New York College at Cortland, 2004 A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE in THE FACULTY OF GRADUATE STUDIES (Geological Sciences) THE UNIVERSITY OF BRITISH COLUMBIA (Vancouver) November 2009 © Emily Kathryn Hopkin, 2009 Abstract The development of conodont biochronology for the Triassic Period is hindered by the lack of understanding of the genus Metapolygnathus Hayashi, 1968a and, to a lesser extent, Carniepigondolella Kozur, 2003. Specimens of these genera collected at Klaskino Inlet, British Columbia are described as species populations of M. polygnathiformis s.l., M. carpathicus , and M. nodosus and variations within these species populations are identified. The morphological variations on platform shape, relative strength of anterior platform nodes, the “communisti trend,” fused carinal nodes and an extra carinal node are shared between all species populations. Although it is beneficial to fully document the generic variability within Metapolygnathus , these variations should not be included in the genus description. Not all variations occur in all species of the genus and only three species were looked at in this thesis. The secondary focus of this thesis addresses the uncertain position of the allochthonous terrane Wrangellia in the Late Carnian. Using paleobiogeographic techniques, data on ammonoid genera occurrences were compiled for cratonic North America, Wrangellia, and the western Pacific, and then compared using the Dice coefficient. It is concluded that ammonoid similarity levels are too low to assess significance levels. Based on the collected data, however, it appears that the Wrangellian fauna is most similar to the fauna of the middle paleolatitude of the North American craton.

[email protected] Received: 26/02/06 / Accepted: 09/10/06 Abstract Sephardiellinae (nov. subfam.) encompasses a Middle Triassic Gondolleloid lineage that originated in the Sephardic realm, west- ernmost shallow Neotethys, from where, in the course of the Ladinian and earliest Carnian, some of its species spread to the world oceans, before extinction as a result of the Carnian salinity crisis. It is composed of two genera, Sephardiella and Pseudofurnishius. Differential criteria in its septimembrate apparatus are the basal cavity structure of P1 element and morphological variations in the P2 and S3 elements. Keywords: Conodonts, Middle Triassic, Sephardiellinae, Sephardic Realm, Neotethys. Resumen La nueva subfamilia Sephardiellinae está comprendida dentro del linaje de Gondolellidae del Triásico Medio y se originó en el Dominio Sefardí, la parte más occidental del Neotetis. Durante el Ladiniense-Carniense Inferior, algunas de sus especies irradian y se distribuyen por todos los océanos. Su extinción está relacionada con la crisis de salinidad que tuvo lugar en el Carniense. La nueva subfamilia está constituida por dos géneros, Sephardiella y Pseudofurnishius las diferencias morfológicas de su aparato sep- timembrado, como son la estructura de la cavidad basal del elemento P1 y las variaciones morfológicas de los elementos P2 y S3, constituyen el criterio utilizado.

[email protected] 2 Department of Geosciences, University of Padova, Via Giotto 1, Padova, I-35137. Pizzo Mondello (Sicani Mountains, Western Sicily, Italy) is one of the best sites for the study of the Carnian/Norian boundary and of Upper Triassic conodonts phylogenesis as well. Pizzo Mondello section is a 450 m thick continuous succession of pelagic-hemipelagic limestones (Calcari con selce or Halobia Limestone auctorum; Cherty Limestone, MUTTONI et al, 2001; 2004) consisting in evenly-bedded to nodular clacilutites (mostly mudstones/wackestones with radiolarians) rich in bivalves (Halobia) and ammonoids, with cherty lists and nodules (GUAIUMI et al., 2007; NICORA et al., 2007). Conodonts are very abundant giving the opportunity to observe and to point out clear relationships among the four most widespread Upper Carnian/Lower Norian conodont genera (Paragondolella, Carnepigondolella, Metapolygnathus and Epigondolella) and to identify trends of the genera turnovers. Genera have been classified and separated following the original diagnosis given by the Authors, regarding also as discriminating for the genera taxonomy the following morphological elements: position of the pit, with respect both to the platform and to the keel; shape of the keel end; length of the platform and occurrence of nodes and/or denticles on the platform margins.

Kozur &. H. Mostler SUMMARY The Permian-Triassic boundary is studied in Dolpo area (Tibetan Zone, Nepal) of the lower Himalaya Range. The microfauna dissolved from limestone with acetic acid, is rich on well preserved conodonts only, in the Upper Permian strata they are ill pre- served. The highest part of the Thini-Chu-Formation, strata with a typical micro- fauna of Permian age (Dorasham substage of Dzhulfa stage) are overlain by a sequence of Lower Triassic limestone, shale, sandy shale and marl 17 m to 30 m thick. The conodont fauna of this sequence is described and the stratigraphical range of them is discussed; they belong to the higher Brahmanian stage (Gandarian substage) Jakutian and Olenekian stage. A classification of Conodont-Zone s (partly Assemblage Zones) of the Lo- wer Triassic is prepared and an attempt of correlation with Ammonoid Zones is done. A new genus and species is established, the genus Platyvillosus is revised. Diese Arbeit wurde vom Fonds der wissenschaftlichen Forschung in Österreich unterstützt. Anschrift der Verfasser: Dipl.

Conodont biostratigraphy of a Carnian-Rhaetian succession at Csovár,˝ Hungary Viktor Karádi Department of Paleontology, Eötvös Loránd University, Budapest, Hungary ([email protected]) The global biozonation of Upper Triassic conodonts is a question still under debate. The GSSPs of the Carnian- Norian and Norian-Rhaetian boundaries are not yet defined, thus every new data contributes to the solution. In north-central Hungary the Csovár˝ borehole exposed a nearly 600 m thick Carnian-Rhaetian succession of cherty limestones and dolomites that represent toe-of-slope and basinal facies. The aim of this study was to give a detailed biostratigraphical analysis of the borehole material based on conodonts. Although the amount of the material was quite low (half kg/sample) a rich conodont fauna was found, 37 species of 9 genera could be identified. The iden- tified conodont zones and their main features are as follows: - Misikella ultima Zone (upper Rhaetian): appearance of M. ultima; - Misikella posthernsteini Zone (lower Rhaetian): appearance of M. posthernsteini, decrease in number of M. hern- steini; - Misikella hernsteini-Parvigondolella andrusovi Zone (upper Sevatian): appearance of Oncodella paucidentata and P. andrusovi, presence of M. hernsteini; - Mockina bidentata Zone (lower Sevatian): appearance of M. bidentata, diversification of genus Mockina, appear- ance of M. hernsteini; - Epigondolella triangularis-Norigondolella hallstattensis Zone (upper Lacian): appearance of advanced forms of E. triangularis, presence of E. uniformis; - Epigondolella rigoi Zone (middle Lacian): increase in number of E. rigoi, presence of advanced forms of E.

We propose new regional correlations of the Mersin mélanges with other mélange-like units or similar series, located both in southern Turkey and adjacent regions. The palaeotectonic implications of the correlations are also discussed. The main results may be summarized as follows: the infra-ophiolitic mélange is subdivided into two units, the Upper Cretaceous Sorgun ophiolitic mélange and the Ladinian−Carnian Hacialanı mélange. The Mersin mélanges, together with the Antalya and Mamonia domains, are represented by a series of exotic units now found south of the main Taurus range, and are characteristic of the South-Taurides Exotic Units.

  • Beiträge Zur Paläoökologie Der Triasconodonten
    Beiträge zur Paläoökologie der Triasconodonten von H. Kozur+) Zusammenfassung Salinitätsgehalt, Tiefe, Temperatur, aber auch der Energieindex und der Sauerstoffgehalt des Wassers spielen neben dem Substrat eine große Rolle für das Auftreten der triassischen Conodonten. Conodonten fehlen in extrem flachem Wasser, z.B. intertidalen Kalken, sie sind sehr selten in Dasycladaceen-reichen Kalken, fehlen in Riffkalken und anderen Hartbodensedimenten. Sehr viele Conodontenwurden in kalkigen euhalinen marinen Weichbodensedi­ menten mit Ausnahme von psychrosphärischen Tiefwassersedimenten gefunden. Die meisten triassischen Conodonten sind stenohalin, einige Arten euryhalin. Eine Reihe davon ist stenotherm wie z.B. Gladigondolella, andere wiederum eurytherm wie z.B. die vielen Gondolella-Arten. In Flachwassersedimenten mit starker Turbu­ lenz (hoher Wellenenergie)gibt es nur robuste Conodonten. Die Conodonten leben . in Wasser mit einern relativ .geringen Sauerstoffgehalt, aber sie benötigen stets einen höheren Sauerstoffgehalt als die Scolecodonten. Es konnten nie. mehr als drei bis vier natürliche Conodonten-Vergesellschaftungen (natür• liche Arten) in einern Environment bzw. an einem Platz gefunden werden. In einern Environment, das nicht besonders geeignet für Conodonten ist, sind es höchsten ein bis zwei natürliche Conodon­ tenarten. Dieses Untersuchungsergebnis ist von enormer Bedeutung für die Multielementtaxonomie. Die paläoökologischen Untersuchungen der triassischen Conodonten zeigen folgendes auf: 1) Die Conodonten-führenden Organismen
