The sedimentary strata were sampled in the lesser Himalayas to probe paleoenvironmental changes across Cretaceous-Paleogene (K-Pg) boundary eastern Tethys. study provides an integrated lithologic and bio-sequence stratigraphic analysis, leading paleoecology interpretations. planktic foraminiferal limestone of late Cretaceous is overlain by lateritic sandstones sandy limestones, latter being Pal...
An isolated dinosaur vertebra from the marine deposits of the Maastrichtian type area, near the city of Maastricht (The Netherlands), collected during the 19th century and kept in the palaeontological collection of the Museum für Naturkunde in Berlin, is described as a caudal vertebra of a hadrosaurid ornithopod. Although it cannot be identified with greater accuracy, this specimen is an additi...
An upper Campanian to Oligocene stratigraphic succession has been examined from six deep exploration wells in the Palmyrides area of Syria. Most sedimentary contains rich and well moderately preserved planktonic foraminiferal assemblages that enable successful age determination. The Maastrichtian fauna is highly diverse with domination warm water taxa such as Globotruncana aegyptiaca, Gansserin...
Pre-Mesozoic exotic crystalline blocks within the Outer Carpathian flysch have potential to unravel nature of their eroded basement source(s) and reconstruct Paleozoic–Precambrian history Protocarpathians. Strongly tectonized Campanian–Maastrichtian grey marls in Subsilesian Nappe Western Carpathians Poland contain a variety different lithology types, including granitoids andesites. Petrologica...
