The extent of the Oligocene sands and wedge unit and the Utsira and Skade formations is according to Rundberg & Eidvin (2005). The extent of the Molo Formation is according to Bullimore et al. (2005). The extent of the North Sea Oligocene play (NOL-1) is according to the Norwegian Petroleum Directorate web page (www.npd.no). The provenance study is after Olivarius (2009) and the topographic map is after Olesen et al. (2010). The extent of the Hutton sand (Oligocene-Upper Pliocene, informal) is modied Mapafter Gregersen & Johannessen 1 (2007). In the British sector, the Lower Miocene part of the Hutton sand probably corresponds to the Skade Formation in the Norwegian sector and the Upper Miocene-Lower Pliocene part of the Hutton sand probably corresponds to the Utsira Formation in the Norwegian sector.

The so-called ‘river dolphins’ are now recognized as independent lineages that converged on similar morphological specializations (e.g., longirostry). In South America, the two endemic ‘river dolphin’ lineages form a clade (Inioidea), with closely related fossil inioids from marine rock units in the South Pacific and North Atlantic oceans. Here we describe a new genus and species of fossil inioid, Isthminia panamensis, gen. et sp. nov. from the late Miocene of Panama. The type and only known specimen consists of a partial skull, mandibles, isolated teeth, a right scapula, and carpal elements recovered from Submitted 27 April 2015 the Pina˜ Facies of the Chagres Formation, along the Caribbean coast of Panama.

The specimens are all referred to the taxon Psephophorus polygonus and constitute the northernmost occurrence of this taxon in the geological record. Additionally, they indicate that leatherback turtles were a common constituent of the marine fauna of the Late Miocene North Sea Basin.

  • Palaeogeography and Facies Distnbution in the Tertiary of Denmark and Surrounding Areas
    Palaeogeography and Facies Distnbution in the Tertiary of Denmark and Surrounding Areas NILS SPJELDNÆS Spjeldnæs, N. 1975: Palaegeography and facies distribution in the Tertiary of Denmark and surrounding areas. Norges geol. Unders. 316, 289-311. A short review of the stratigraphical terminology and nomenclature of the Danish Tertiary is presented. The Lower Paleocene (Danian) is lithologically similar to the Upper Cretaceous but has a more variable facies distribution, and is mainly restricted to the area north of the Fyn-Ringkøbing ridge. The Upper Paleocene (Selandian) is also variable in facies and consists mostly of glauconitic clays and maris. In the Eocene, volcanic ash, diatomites and extremely fine-grained clays were deposited. One of the still incompletely understood palaeogeographical peculiarities in the area during the Cretaceous to Oligocene is the predominance of sediments and faunas of open oceanic, and partly deep water type close to the Fennoscandian (Baltic) Shield. Possible explanations for this anomaly are discussed. In the Upper Oligocene terrigenous clastic sand begins to appear in quantity, and the Miocene is dominated by an alternation between terrestrial/limnic sands with lignite, and marine, glauconitic and micaceous clays and sands. A Miocene drainage system from the east and north-east can be discerned, and it appears to be shifted towards the south during the Pliocene, possibly reflecting the uplift of the Atlantic margin of the Fennoscandian Shield. The mechanism and and timing of this tectonic event is not completely understood, but it must have been of major importance for the palaeogeographical development of the region, and for the formation of the sedimentary basins.

    Dinoflagellate cyst stratigraphy of the Miocene Hodde and Gram Formations, Denmark STEFAN PIASECKI Piasecki, S.: Dinoflagellate cyst stratigraphy of the Miocene Hodde and Gram Formations, Denmark. DGF Bull. geol. Soc, Denmark, vol. 29, pp. 53-76, Copenhagen, June 10th, 1980. A dinoflagellate cyst stratigraphy is proposed for the Hodde and Gram Formations in western Jylland, Denmark. Four biozones are defined and the formations are dated by dinoflagellate cysts to be of Middle and Upper Miocene age, which supports previous dating by molluscs. One new genus and four new species are described: Labyrinthodinium truncatum gen. nov. sp. nov., Dinopterygium verriculum sp. nov., Ap- teodinium tectatum sp. nov. and Nematosphaeropsis aquaeducta sp. nov.
