Better molecular preservation of organic matter in an oxic than in a sulfidic depositional environment: Evidence from Thalassiphora pelagica (Dinoflagellata, Eocene) cysts

Anoxic sediments, as compared to oxic settings, encompass a much higher proportion of relatively labile and thus more reactive organic matter, naturally giving rise to structural changes of the organic molecules themselves, as well as cross-linking between them (e.g., through reactive sulfur species). Both processes transform the original...

Strong climate coupling of terrestrial and marine environments in the Miocene of northwest Europe

A palynological and organic geochemical record from a shallow marine paleoenvironmental setting in SE Netherlands documents the coupled marine and terrestrial climate evolution from the late Burdigalian (∼ 17 Ma) through the early Zanclean (∼ 4.5 Ma). Proxy climate records show several coeval variations in both relative sea surface (deduced from...

Neogene stratigraphy of the Langenboom locality (Noord-Brabant, the Netherlands)

The locality of Langenboom (eastern Noord-Brabant, the Netherlands), also known as Mill, is famous for its Neogene molluscs, shark teeth, teleost remains, birds and marine mammals. The stratigraphic context of the fossils, which have been collected from sand suppletions, was hitherto poorly understood. Here we report on a section which has been...

Eustatic variations during the Paleocene-Eocene greenhouse world

We reconstruct eustatic variations during the latest Paleocene and earliest Eocene (∼58-52 Ma). Dinoflagellate cysts, grain size fractions, and organic biomarkers in marine sections at four sites from three continents indicate an increased distance to the coast during the Paleocene-Eocene thermal maximum (PETM). The same trend is recognized in...

Diatoms (Bacillariophyceae) and dinoflagellate cysts (dinophyceae) from Rookery Bay, Florida, U.S.A

This paper is a report, on the diatoms and dinoflagellate cysts identified in a sediment core and a water sample recovered from Rookery Bay, a subtropical estuarine system located on the west coast of Florida. Eighty-eight diatom taxa representing 48 genera, many of which have been rarely observed, and 14 dinoflagellate cyst genera with 20 taxa...

The Early Pleistocene Praetiglian and Ludhamian pollen stages in the North Sea Basin and their relationship to the marine isotope record

In this paper, the currently accepted correlation of the Early Pleistocene Ludhamian stage of England with the Tiglian-A sub-stage of the Netherlands is challenged. Recent investigations of Early Pleistocene marine North Sea deposits from a borehole near Noordwijk (the Netherlands) yielded evidence from molluscs, dinoflagellate cysts and...

Chronostratigraphy of Late Neogene sediments in the southern North Sea Basin and paleoenvironmental interpretations

A chronostratigraphic framework has been established for Upper Neogene sediments from the northern Netherlands offshore sector, southern North Sea. Data of dinoflagellate cysts, pollen and foraminifers from eight boreholes are integrated and the resulting biostratigraphic events are connected to an additionally retrieved paleomagnetic record....

Integrated chronostratigraphy of the Pliocene-Pleistocene interval and its relation to the regional stratigraphical stages in the southern North Sea region

Time-stratigraphic interpretations of Late Pliocene to Early Pleistocene sediments from onshore locations and from marginal marine settings of the North Sea Basin often refer to the subdivision of the Dutch and British 'Quaternary' regional stratigraphic stages. Since age control for these stages and their stage boundaries are based on relative...
