On the Barents Shelf, northernmost and least explored hydrocarbon province of Norwegian Continental Upper Jurassic organic-rich shales have traditionally been given most attention as these represent prolific source rock unit region. However, in western frontier areas is too deeply buried. By combining high-resolution 2D seismic data, well logs, digitalized Rock-Eval this study documents lateral...

BACKGROUND AND AIMS The mid-Cretaceous is a period of sudden turnover from gymnosperm to angiosperm-dominated floras. The aim was to investigate the fossil plant ecology in order to follow the spread of angiosperm taxa. METHODS Floristic lists and localities from the latest Albian-Cenomanian of Europe are analysed with Wagner's Parsimony Method, a clustering method currently used in phylogeny...

The deep ocean conditions and circulation during the Cretaceous have been characterized mainly by the sediments from the Tethys Sea and the proto-Atlantic Ocean, because sedimentological data from the Pacific basin from that period have been quite limited. Here we present new geochemical measurements from sediments that we collected from two sites in Hokkaido, Japan, that were presumably deposi...

Mammals of metatherian-eutherian grade are represented in a collection recovered from a Wise County, Texas, locality of Lower Cretaceous (Albian) age. The form, or forms, are distinctly primitive as evidenced by the very small low protocones, large stylar cusps, and wide stylar shelf. The presence of well-developed and separate metacones at such an early date would seem to place Deltatheridium ...

Brachyuran specimens collected from the Albian (Early Cretaceous) age Shell Creek Shale in Montana and Wyoming provide the basis for description of two new species, Zygastrocarcinus waagei and Componocancer roberti. The former represents only the fourth species of a genus that is endemic to the Cretaceous of mid-continental North America. The latter species is assigned to a new superfamily, Com...

Lower Cretaceous fossils from central Niger document the succession of sauropod dinosaurs on Africa as it drifted into geographic isolation. A new broad-toothed genus of Neocomian age ( approximately 135 million years ago) shows few of the specializations of other Cretaceous sauropods. A new small-bodied sauropod of Aptian-Albian age ( approximately 110 million years ago), in contrast, reveals ...

A new fossil caridean shrimp, Kellnerius jamacaruensis n. gen. n. sp., of the early Cretaceous (Albian) from the Romualdo Formation, Araripe Basin, northeastern Brazil is described and illustrated. The new species is compared to known fossil palaemonids found in Brazil. Kellnerius jamacaruensis n. gen. n. sp. is easily differentiated from the other palaemonids by a rostrum with 5 spines, an enl...
