Atolls are faithful recorders helping us understand eustatic variations, the evolution of carbonate production through time, and changes in magmatic hotspots activity. Several early Cretaceous Mid-Pacific atolls were previously investigated ocean drilling, but due to low quality vintage seismic data available, few spatial constraints exist on their stratigraphic large-scale diagenesis. Here, we...

The paleoenvironmental impact of the early Aptian Ocean Anoxic Event 1a (OAE 1a, ca. 121 Ma) has been investigated in detail Cismon Core (Lombardy Basin, western Tethys) by using different geochemical and micropaleontological proxies. We provide first high-resolution data benthic foraminiferal assemblages through upper Barremian - lower stratigraphic interval. Benthic foraminifera are integrate...

The Mannar Basin extends over 45,000 km2 off the western coast of Sri Lanka. It has evolved due to multiphase rifting between Indo-Lanka landmasses during Barremian-Paleocene time. sediment thickness basin ranges from about 4 10 km. northern part is a targeted area for hydrocarbon exploration in Though two natural gas discoveries were made 2011, remains frontier lack well penetration and 3D sei...

A 3D numerical modelling workflow was applied to the Barremian—Aptian source rock interval in a shelfal lower slope area of northern Orange Basin, offshore western South Africa. The main objective investigate timing hydrocarbon generation and migration. Hydrocarbon migration has previously been investigated south basin by relating gas escape features with structural elements as seen on seismic ...

The Lower Cretaceous Tuxen (lower Hauterivian – upper Barremian) and Sola (upper Barremian Albian) Formations in the Danish Central Graben (North Sea) constitute one of oldest chalk successions recorded globally, but have received little attention with regards to sedimentary facies depositional processes. This study presents first comprehensive carbonate analysis succession, retrieved from seve...

BACKGROUND The Yellow Cat Member of the Cedar Mountain Formation (Early Cretaceous, Barremian?--Aptian) of Utah has yielded a rich theropod fauna, including the coelurosaur Nedcolbertia justinhofmanni, the therizinosauroid Falcarius utahensis, the troodontid Geminiraptor suarezarum, and the dromaeosaurid Utahraptor ostrommaysorum. Recent excavation has uncovered three new dromaeosaurid specimen...

Abstract This work provides the detailed investigation (taxonomy, biostratigraphy, and paleoecology) of a nonmarine ostracod fauna from Shinekhudag Formation in Gobi–Altai area, southwest Mongolia. The samples two sections (Tsagaan Tsuvarga Oshih Hollow East) yielded various ostracods assigned to nine species belonging six genera: Cypridea verrucata Neustrueva, 1974, C. ihsienensis Hou, 1958, u...

A new genus and species of non-hadrosaurid hadrosauriform dinosaur, Brighstoneus simmondsi gen. et sp. nov., is described from the Lower Cretaceous Wessex Formation Isle Wight. The taxon has two autapomorphies, a nasal having modest bulla with convex sides, primary accessory ridges on lingual aspect maxillary crown. dentary at least 28 alveolar positions, which highest number recorded in an orn...

The mid-Cretaceous histories (origin, growth, death) of algal-rudist-stromatoporoid reef communities located on many Pacific Basin guyots are complex and controversial. These shallow water, tropical communities originated on volcanic edifices extruded during the Barremian-Albian, grew upward during edifice subsidenceftransgression throughout the Aptian, Albian and Cenomanian and several of them...
