The Late Cretaceous-Early Paleocene Shiranish and Aliji formations have been studied in three selected wells Jambur Oil Field (Ja-50, Ja-53, Ja-67) Kirkuk, Northeastern Iraq. This study included lithostratigraphy biostratigraphy. Campanian-Maastrichtian Formation consist mainly of thin marly chalky limestone beds overlain by marl beds, with some representing an outer shelf basinal environment, ...

I sland faunas are natural laboratories of evolutionary change and have long fascinated biologists. The peculiar ecological conditions on islands have frequently led to the evolution of endemic taxa that differ dramatically in body size and/or morphology from their mainland relatives. Many large animals tend to become smaller on islands, and small ones generally become larger—a phenomenon known...

The northern Oman margin is a key area for understanding the emplacement of Semail Ophiolite and obduction processes in general. This study uses grid 2D-multichannel seismic lines tied to well data characterize offshore domain reappraises post-obduction history margin. West Muscat, Sohar basin, late Cretaceous Paleogene tectonic mega-sequence records syn- late-obduction stages deposition erosio...

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...

The Maastrichtian Javelina Formation of southwestern Texas comprises a thick sequence stream channel and floodplain deposits accumulated in broad southeast-trending valley, several hundred kilometers inland from the Late Cretaceous shoreline. Three pterosaur species are found here. Remains Quetzalcoatlus lawsoni, sp. nov., concentrated shallow alkaline lakes that developed abandoned reaches cha...

Well-sampled dinosaur communities from the Jurassic through early Late Cretaceous show greater taxonomic diversity among larger (>50 kg) theropod taxa than of Campano-Maastrichtian, particularly to those eastern/central Asia and Laramidia. The large carnivore guilds in Asiamerican assemblages are monopolized by tyrannosaurids, with adult medium-sized (50–500 predators rare or absent. In cont...
