a succession of late campanian- early maastrichtian is analyzed from gurpi formation with regard to the calcareous nannofossils. correlation matrix was applied for the first time to the entire nannofossil assemblage to reconstruct environmental conditions. a detailed quantitative calcareous nannofossil analyses is performed on samples in order to further investigate the climate events, and inte...

The biostratigraphy of the Outer Carpathians is based mainly on ranges agglutinated foraminifera. Species acmes provide opportunity to enhance and support existing biozonations. Assemblages foraminifera from Campanian Eocene various tectonic-structural units were analyzed in terms their qualitative quantitative occurrence. In this stratigraphic interval, 19 species display significantly increas...

Three drivers of subsidence are recognized in the Western Interior Basin: Mesozoic–early Cenozoic flexure adjacent to thin-skinned, eastward propagating Sevier Orogeny, Late Cretaceous–Eocene associated with thick-skinned Laramide Uplifts and Cretaceous dynamic subsidence. This study combines outcrop lithofacies, palaeocurrent measurements, detrital zircon geochronology, biostratigraphy, strati...

BACKGROUND Rhabdodontid ornithopod dinosaurs are characteristic elements of Late Cretaceous European vertebrate faunas and were previously collected from lower Campanian to Maastrichtian continental deposits. Phylogenetic analyses have placed rhabdodontids among basal ornithopods as the sister taxon to the clade consisting of Tenontosaurus, Dryosaurus, Camptosaurus, and Iguanodon. Recent studie...

This paper gives a detailed overview of biotic assemblages recovered from the Deccan trap intercalated sedimentary sequences (infraand intertrappean beds) of peninsular India as a result of extensive research done during the last 20 years. The infraand intertrappean beds contain remnants of Gondwanan forms such as myobatrachinae frogs, pelomedusid turtles, dinosaurs (i.e. titanosaurids and abel...
