The Central Iran Basin is a region with unique environmental characteristics in which the Late Paleogene–Early Neogene benthic foraminifera display distinctive distributions and abundances that can assist identifying intervals best reservoir potential. Lipidocyclinid miogypsinid zonal marker taxa this be correlated those SBZ23 (European Basin), indicating an Oligocene (Chattian) age. With sedim...
Forty two Paleocene benthic foraminiferal species of the Midway Formation in the Gulf Coastal Plain of Texas, USA were firstly investigated by Plummer (1927), and its paleogeographic distribution in some other countries in the Tethyan province were recorded: North America (USA, Mexico), South America (Argentina), Europe (North Sea Basin, Spain, France, Italy, Czech Republic, Bulgaria), North Af...
Integrated sedimentological, palynological, and palynofacies analyses of the Arrifes section in central Algarve Basin (southern Portugal) provided new information on age environments this Lower Cretaceous sequence. The sedimentary succession at consists fossiliferous interbedded limestones, marly marls, dated as latest Hauterivian to late Barremian (Lower Cretaceous) based key dinoflagellate ta...
The Cretaceous breakup of Gondwana strongly modified the global distribution of shallow tropical seas reshaping the geographic configuration of marine basins. However, the links between tropical reef availability, plate tectonic processes and marine biodiversity distribution patterns are still unknown. Here, we show that a spatial diversification model constrained by absolute plate motions for ...
Crittenden Springs in northeastern Nevada yields M. gracilitatis Zone ammonoids renowned for the finely detailed, exquisite preservation of the test, which sometimes even displays relict color patterns. Evidence reveals most of the fossiliferous Lower Triassic beds in the Crittenden Springs area are overturned and this conclusion places the Meekoceras gracilitatis Zone portion of the section an...
The present-day tectonic setting of the Western Mediterranean region, from Pyrénées to Betics and Alps Atlas, results a complex 3-D geodynamic evolution involving interactions between Africa, Eurasia Iberia plates asthenospheric mantle dynamics underneath. In this paper, we review main events recorded in region since Early Cretaceous discuss respective effects far-field near-field contributions...
