Accepted 6 July 2014 The main purpose of the study is to compare the ages of the Danish succession suggested by the biostratigraphic Available online 18 July 2014 zonation on dinoflagellate cysts (Dybkjær and Piasecki, 2010) with the ages based on analyses of the 87Sr/86Sr composition of marine calcareous fossils in the same succession. Keywords: Strontium isotope stratigraphy Analyses of samples from the Danish Brejning, Vejle Fjord, Klintinghoved, Arnum, Odderup, Hodde, Ørnhøj and Danish Upper Oligocene–Miocene succession Gram formations gave ages between 25.7 My (late Oligocene) and 10.3 My (late Miocene). The Sr isotope ages from the lower part of the succession, i.e. Brejning to Odderup formations, agree with the age estimates based on biostratigraphy. However, the 87Sr/86Sr ratios of fossil carbonates from the middle–upper Miocene, Hodde to Gram succession consistently indicate ages older than those recorded by biostratigraphy. Post-depositional process- es as an explanation for this offset are inconsistent with good preservation of shell material and little reworking. A palaeoenvironmental cause for the observed mismatch is therefore indicated. Search for geological events that could explain the older ages obtained by Sr isotope compositions have not led to any conclusions and we had recognised the same problem in earlier reports and communications. We conclude that this is a general and possibly global, middle–late Miocene problem that has to be reconsidered and explained geologically. © 2014 The Authors. Published by Elsevier B.V.

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.

  • 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.
