For the lithostratigraphy and microbiostratigraphical studies, a stratigraphical section (named Dareh-Goshayesh) has selected and is located in southeast of Maragheh city, south of eastern Azerbaijan province in the northwest of Iran. The thickness of successions in the selected stratigraphic section is measured about 223.6 m. The mentioned studied stratigraphic section is composed of two clast...

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...

For the microbiostratigraphical studies, a stratigraphical section (named Dareh-Goshayesh) has been selected in southeast of Maragheh, Northwestern Iran. The thickness of successions in the selected stratigraphic section is measured about 223.6 m. The mentioned studied stratigraphic section is composed of two clastic and carbonate units. This succession unconformably overlies the Lar Formation ...

This paper discusses the lithostratigraphy of the Xinminbao Group in the Mazongshan area of Gansu Province, northwestern China, and the correlation of its biota. The Xinminbao Group was deposited in a fluviolacustrine setting in Mesozoic graben basins under a semi-arid, subtropical climate. The fossil sites concentrated in the lower part of the group have yielded dinosaurs, mammals and other ve...

The sauropod of El Oterillo II is a specimen that was excavated from the Castrillo de la Reina Formation (Burgos, Spain), late Barremian-early Aptian, in the 2000s but initially remained undescribed. A tooth and elements of the axial skeleton, and the scapular and pelvic girdle, represent it. It is one of the most complete titanosauriform sauropods from the Early Cretaceous of Europe and presen...

The Mesozoic, mid-Cretaceous (Barremian to Cenomanian) deposits of southern Croatia comprise a succession of shallow tropical-water, inner-platform deposits that formed on a Bahama-type isolated Adriatic carbonate platform in the Dinarides. This succession is dominated by benthic foraminifers and dasycladalean algae, and is exposed in a nearly continuous outcrop section on the islands and along...

The majority of environments are dominated by flowering plants today, but it is uncertain how this dominance originated. This increase in angiosperm diversity happened during the Cretaceous period (ca. 145-65 Ma) and led to replacement and often extinction of gymnosperms and ferns. We propose a scenario for the rise to dominance of the angiosperms from the Barremian (ca. 130 Ma) to the Campania...

Abstract A combined micropalaeontological, taphonomical and sedimentological study was carried out in the non-marine Barremian of Maestrat Basin (E Iberian Chain) to elucidate palaeoecology charophytes. Understanding fossil charophytes is prime importance for accurate application charophyte biozonations, since most species used as biostratigraphic markers and/or biozone index are restricted fac...

Abstract The Jebel Oust region (north-eastern Tunisia) recorded two levels of marine black shale in the Lower Cretaceous marly series. Geodynamic evolution, biostratigraphic and Rock–Eval analysies allow classifying those shales as unconventional oil resource systems that were deposited during oceanic anoxic events: Middel Barremian Event "MBE" Early Aptian "OAE1a". Paleogeographic evolution hi...
