The deposits corresponding to the Upper Cretaceous Neuquén and San Jorge Gulf basins from northern central Patagonia have provided two of most complete sequences terrestrial vertebrate faunas all Gondwanan landmasses. Among carnivorous components, carcharodontosaurid theropods appeared as common elements during Early earliest Late in Patagonia. Although recorded mostly lower Turonian, isolated ...

Hadrosauriformes is a group of ornithopod dinosaurs with rich and extensive Cretaceous track record. However, their rear foot (pes) anatomy rather conservative. Thus, distinguishing different putative producers from morphological differences often impeded unless identification corroborated by stratigraphic geographic distribution. On the contrary, forefoot (manus) hadrosauriform taxa reflects d...

The Cenomanian to early Santonian interval is usually considered a time of postrifting tectonic quiescence around the northern margins Iberia that preceded onset Pyrenean convergence by crustal thrusting in latest Santonian. However, plate kinematic models Mesozoic evolution poorly constrain Turonian-Santonian position relative Eurasia. This study reconstructs changes sedimentary facies and arc...

Three well - known source rocks of the Zagros basin and the Persian Gulf are Mesozoic in age.The Jurassic Sargelu, Albian Kazhdumi and Neocomian-Coniacian Garau formations have charged the Cretaceous reservoirs of this area. The northwest part of the Persian Gulf is strongly influenced by two major N-S trending paleohighs (Hendijan- Bahregansar-Regesafid-Izeh and Kharge- Mish) and surrounding p...

We investigated the environmental conditions that prevailed in continental ecosystems recorded sedimentary deposits of Japan during Cretaceous through analysis oxygen and carbon isotope compositions phosphate (?18Op) apatite-bound carbonate (?18Oc ?13Cc) vertebrate teeth bones. Local surface water ?18Ow values were calculated using known phosphate-water fractionation equations. Anomalously low ...
