Fossil-wood carbon-isotope data are presented for the Wessex Formation, a non-marine unit within the Lower Cretaceous (Valanginian–Barremian) Wealden Group of the Isle of Wight and Dorset, southern England. The carbon-isotope values have a range ( C c. 26.6 to 19.8‰) that is consistent with that expected for Mesozoic C3 plants. Consideration of the Isle of Wight fossil-wood carbon-isotope data ...

Jurassic and Lower Cretaceous successions of the Manin Unit Central Western Carpathians are exposed in Butkov Quarry Middle Vah Region, Slovakia. A significant part macrofauna belonging to neocomitid ammonites, formerly classified under genus Teschenites Thieuloy, 1971, occurs deposits spanning Valanginian/Hauterivian boundary. The original definition was accompanied by uncertainties taxonomic ...

A Valanginian to Barremian bathyal foraminiferal assemblage (118 taxa belonging to 51 genera) is documented from ODP Site 766, drilled near the foot of the Exmouth Plateau off northwest Australia. The majority of taxa are cosmopolitan species previously described from the boreal assemblages of northern Europe and the northern margins of the Tethys, but 32 taxa could not be assigned to previousl...

Benthic foraminifera at Ocean Drilling Program (ODP) Hole 692B were studied to understand variations in oxygen and organic-matter fluxes bottom waters during the Early Cretaceous. The upper Berriasian lower Barremian black shales, characterized by high concentrations of total organic carbon (TOC) ranging between 1.3 18%, deposited an outer neritic-upper bathyal environment (~200–500 m) accordin...

Herein are presented the results of detailed bio- (calcareous dinocysts, calpionellids, foraminifers, saccocomids) and chemostratigraphic (δ13C) studies combined with high-resolution microfacies, rock magnetic and gamma-ray spectrometry (GRS) investigations performed on upper Kimmeridgian–upper Valanginian carbonates of Giewont succession (Tatricum, Maly sections, Western Tatra Mountains, Polan...
