  1. 6. Tooth Replacement of Euhelopus zdanskyi (Dinosauria: Sauropoda) and the Evolution of Titanosaurian Tooth Morphology

    University essay from Uppsala universitet/Paleobiologi

    Author : Seela Salakka; [2014]
    Keywords : Euhelopus; Sauropoda; tooth replacement; tooth morphology; evolution; Titanosauria;

    Abstract : Sauropod tooth morphologies and tooth replacement patterns bear important information on feeding habits and sauropod evolution. Euhelopus zdanskyi is an Early Cretaceous neosauropod, and belongs to the group Euhelopodidae, which is the sister group of Titanosauria. READ MORE

  3. 7. Paleoecology and sedimentology of the Upper Cretaceous (Campanian), marine strata at Åsen, Kristianstad Basin, Southern Sweden, Scania

    University essay from Lunds universitet/Geologiska institutionen

    Author : Faisal Javed Iqbal; [2013]
    Keywords : Campanian; Belemnellocamax mammilatus Zone; Belemnellocamax balsvikensis Zone; Brachiopods; Bivalves; Belemnites; Bryozoans; Barnacle; Sea urchin; corals; coprolites; shark teeth; vertebrate fossils; XRF; Sr Ca; Steinkern; Earth and Environmental Sciences;

    Abstract : The Campanian marine strata from Åsen, north east part of the Kristianstad Basin (southern Sweden) contain a most diverse vertebrate and invertebrate marine fossil assemblages. A diverse fossil fauna was collected from Campanian deposits from a ca. 4.15m thick section during June-August 2010-2012. READ MORE

  4. 8. Mapping of Lower Cretaceous (Knurr Sandstone) turbidite lobes using Seismic Stratigraphy and prospectivity along the southern Loppa High Margin, Hammerfest Basin, Barents Sea, Norway

    University essay from Geofysik

    Author : Nauman Sattar; [2008]
    Keywords : ;

    Abstract : The Hammerfest Basin was formed through downfaulting in Late Jurassic-Early Cretaceous times, allowing the deposition and preservation of Jurassic sediments which later were covered by thick Cretaceous sequences filling in the basin. This study has been conducted along the southern margin of the Loppa High to develop a complete sequence stratigraphic framework and to map Early Cretaceous Knurr Formation turbidite lobes along the slope of the High.

  5. 9. 40Ar/39Ar datering av basalter i Skåne, S Sverige : bevis för två pulser vid 191-178 Ma och vid 110 Ma, samt deras relation till uppsprickning av Pangea

    University essay from Lunds universitet/Geologiska institutionen

    Author : Ingemar Bergelin; [2006]
    Keywords : Skåne; basalt; jura; krita; geokronologi; 40Ar 39Ar; geokemi; Scania; Jurassic; Cretaceous; geochronology; geochemistry; Earth and Environmental Sciences;

    Abstract : Under karbon och perm sammansmälte huvuddelen av jordens kontinenter till en gigantisk landmassa som fått namnet Pangea. Denna blev efterhand instabil och började mot slutet av trias, men framför allt under Jura, att fragmentera i ett antal mindre kontinentala plattor. Detta skedde under omfattande och ibland våldsam vulkanism. READ MORE

  6. 10. Correlation between diagenesis and sedimentary facies of the Bentheim Sandstone, the Schoonebeek field, The Netherlands

    University essay from Lunds universitet/Geologiska institutionen

    Author : Pär Malmborg; [2002]
    Keywords : Bentheim Sandstone; sedimentary facies; diagenesis; petroleum reservoir; Lower Cretaceous; Valanginian; Lower Saxony Basin; Schoonebeek; Gildehaus; Earth and Environmental Sciences;

    Abstract : The Valanginian (Lower Cretaceous) Bentheim succession of the Schoonebeek field is deposited in a shallow-marine environment along the southern and southwestern coast of the Lower Saxony Basin in eastern Netherlands. Three cores from Schoonebeek field, selected by NAM (Nederlandse Aardolie Maatschappij), and a number of samples from an outcrop in the Bentheim Sandstone at Gildehaus were studied. READ MORE
