Oceanic anoxic event 1d (OAE 1d) has been well studied at northern low latitudes (i.e., in Tethys and the North Atlantic); however, paleoenvironmental response to this high not documented triggering mechanism remains unknown. Here, we address both of these shortcomings by presenting first detailed sedimentary multi-proxy geochemical record OAE southern (60–62°S), obtained from sediments using S...

The Poigny borehole near Provins (Seine-et-Marne) provides the most complete single pristine section through Upper Cretaceous Chalk of Paris Basin. A well preserved and diverse palynoflora including 236 species subspecies organic-walled dinoflagellate cysts (dinocysts) is documented from borehole, together with a high-resolution carbon-isotope curve (δ 13 C carb ) for Coniacian–Campanian interv...

Detailed description of spatio-temporal framework fossil-bearing strata is fundamental significance for understanding the evolution organisms and regional tectonics. The Qujing Haikou formations are two lithological units exposed in eastern Yunnan, southwestern China, both bear rich fossils indicative a Middle Devonian age, while their relationship or lateral correlation remains unclear. Based ...

Bagh Vang Section is located at about 45 km to the Northwest of Tabas and South of Shirgesht areas. In Bagh Vang Section, the Permian deposits of the Jamal Formation with a thickness of 270 m are underlain by the Sardar Formation disconformably. The formation is also transitionally and conformably overlain by Lower Triassic deposits of Sorkh Shale Formation. A total of 124 rock samples have bee...

Microproblematica are microfossils whose suprageneric taxonomic status is unknown. Many microproblematica display an encrusting way of life and can therefore be included in the group of “micro-encrusters” that during the Upper Jurassic were conspicuous components of microbial carbonate crusts (e.g. LEINFELDER et al., 1993; SCHMID, 1996; DUPRAZ & STRASSER, 1999, 2002). These forms are widespread...
