detailed organic petrography analysis were conducted on drill core and cutting samples from the nahr umr (middle albian), burgan (lower albian) and ratawi (hauterivian) formations on the soroosh and nowrooz fields, nw part of the iranian sector of the persian gulf. the thermal maturity of the middle albian nahr umr formation appears to have reached the top of the oil window. the underlying burg...

Abstract A new locality near Tarda on the northern margin of Tafilalt, south eastern Morocco exposes extensive sequences Ifezouane and Aoufous formations fluvial Kem Group (Cretaceous, ?Albian-Cenomanian) western flank Ikfh n’Oufza escarpment Hamada du Meski. The stratigraphic sequence here differs significantly from better known exposures in southern includes a heterolithic alternating grey mu...

Detrital zircon U-Pb ages for 30 Late Jurassic and Cretaceous sandstones from the Eastern Province of eastern New Zealand, combined with previously-published geochronological and palaeontological data, constrain the time of deposition in the Pahau and Waioeka terranes of the Cretaceous accretionary margin of Zealandia, and their adjacent cover strata. The zircon age patterns also constrain poss...

Although rare, dinosaurs are well preserved in calcareous nodules of the Santana Formation (Early Cretaceous, ?Albian) of the Araripe Basin, in northeastern Brazil. So far, including only a spinosauroid and three coelurosaurs, the dinosaur fauna appears depauperate. High theropod diversity in assemblages where other dinosaurs are rare or absent is not unique to the Santana Formation. It is seen...

The external and internal features the microstructure of asymmetric rhynchonellides from Albian–Cenomanian (Cretaceous) transition Alicante Province (Eastern Prebetic, Southeastern Spain) have been herein studied. Previous authors placed these in Cyclothyris difformis , consequently attributing an unquestionable Cenomanian age (Upper Cretaceous) to deposits which they appear. long dorsall...

The Santos Basin, offshore Brazil contains a complex set of salt-tectonic structures, the origins which are debated, that is, Albian Gap and São Paulo Plateau (SPP). is ca. 450 km long, 60 wide feature characterized by post-Albian, counter-regional rollover overlying depleted Aptian salt, in largely absent. SPP, located immediately downdip, defined pre-salt structural high overlain 2.5 thick sa...

A tectonically-controlled forced regression occurred on the western margin of French subalpine basin around Aptian–Albian boundary. It nearly emptied part Vocontian Trough during early and middle Albian. compressional pulse associated with vertical movements along Cevennes fault row its satellites is inferred. This correlated an inverse transgressive trend, both in Paris Basin northern chains. ...

New material of the wasp family Maimetshidae (Apocrita) is presented from four Cretaceous amber deposits - the Neocomian of Lebanon, the Early Albian of Spain, the latest Albian/earliest Cenomanian of France, and the Campanian of Canada. The new record from Canadian Cretaceous amber extends the temporal and paleogeographical range of the family. New material from France is assignable to Guyotem...

Trace fossils provide the only records of Early Cretaceous birds from many parts of the world. The identification of traces from large avian track-makers is made difficult given their overall similarity in size and tridactyly in comparison with traces of small non-avian theropods. Reanalysis of Wupus agilis from the Early Cretaceous (Aptian-Albian) Jiaguan Formation, one of a small but growing ...
