Latest Maastrichtian foraminiferal assemblages from the Husów region (Skole Nappe, Outer Carpathians, Poland)

Late Maastrichtian benthic foraminiferal response to palaeoenvironmental changes: a case study from the AbTalkh Formation, west of Kopeh-Dagh Basin, Iran

Benthic foraminiferal assemblages from Maastrichtian strata, Gansserina gansseri-Abathamphalus mayaroensis Planktonic Foraminiferal Zone, of the AbTalkh Formation at Aitamir section (west of the Kopeh-Dagh basin) were investigated in order to evaluate the palaeoenvironmental changes (organic matter flux and bottom-water oxygenation). Maastrichtian faunal assemblages are well preserved and diver...

Spatial niche partitioning in dinosaurs from the latest cretaceous (Maastrichtian) of North America.

We examine patterns of occurrence of associated dinosaur specimens (n = 343) from the North American Upper Cretaceous Hell Creek Formation and equivalent beds, by comparing their relative abundance in sandstone and mudstone. Ceratopsians preferentially occur in mudstone, whereas hadrosaurs and the small ornithopod Thescelosaurus show a strong association with sandstone. By contrast, the giant c...

Abyssal hills: Influence of topography on benthic foraminiferal assemblages

Sedimentary facies and foraminiferal assemblages from [i]Posidonia oceanica[i] meadows of western Mediterranean Sea

Sedimentary facies and foraminiferal assemblages of sediments sampled into seven Posidonia oceanica meadows from Western Mediterranean Sea were investigated. Six sampling sites are localised in Italy (Maratea, Ponza Island, Santa Marinella, Giglio Island, Osalla and Alghero), and one in France (Argentella, Crovani Bay, Corsica). The role of P. oceanica meadows in the sedimentary processes was i...

The shell morphology of the latest Cretaceous (Maastrichtian) trionychid turtle Helopanoplia distincta

Background Helopanoplia distincta is an extinct soft-shelled turtle (Pan-Trionychidae) for which the type specimen is a fragmentary costal and the inguinal notch portion of the left hypoplastron from the Late Cretaceous (Maastrichtian) Lance Formation of Wyoming, USA that bear a distinct surface sculpture pattern consisting of raised tubercles. Over the course of the past few decades, a number ...
