TL;DR: The effects of the Cenomanian-Turonian Oceanic Anoxic Event (OAE) in the Chalk Sea of NW Europe have been investigated using published macrofossil records combined with new detailed sedimentological, foraminiferal, ostracod, calcareous nannofossil, dinoflagellate cyst and stable-isotope data from Dover, England as mentioned in this paper.

TL;DR: Most of the forms that have been encountered in the Weald Clay Group of southeast England and the Wessex and Vectis Formations on the Isle of Wight are described and/or illustrated in this paper.

TL;DR: Findings contradict the widely held opinion that dinoflagellates did not occupy freshwater habitats until the beginning of the Cenozoic Era and indicate fresh-water origins.

TL;DR: In this article, the Kimmeridgian-Albian Fossil Bluff Formation of eastern Alexander Island is elevated to Group status (Fossil bluff Group) and four formations are recognized within the group (which in ascending order are the Ablation Point, Himalia Ridge, Spartan Glacier and Pluto Glacier Formations), characterised by slumped strata, conglomerates, mudstones and sandstones, respectively.

TL;DR: The analysis of a sedimentary succession on the northern side of the western High Atlas, from Essaouira to Amizmiz, has enabled us to identify, and describe, thirteen formations ranging in age from Tithonian to Clansayesian.

TL;DR: The new material supports a Gondwanan origin of the Trematochampsidae and agrees with a new phylogenetic hypothesis which considers trematochampsids to be the ancestral group of certain lineages of ziphodont mesosuschian crocodiles.

TL;DR: The Dakota Formation of Kansas, USA yielded a diverse assemblage of dispersed plant fossils, consisting of megaspores, seed cuticles, algal cysts, and other small plant fragments as discussed by the authors.

TL;DR: In this paper, seven local biostratigraphic zones have been distinguished in the Albian and Cenomanian sediments of the Pieniny Klippen Belt: Hedbergella assemblage (Assemblage Zone, AZ), R. ticinensis- P. buxtorfi- R. appenninica (CRZ).

TL;DR: The Neogyroporella as mentioned in this paper is a genus of benthiques, which se caracterise par un seul ordre de ramifications disposees en verticille et de type vesiculifere.

TL;DR: In this article, a faune d'ostracodes recueillie dans le forage 95 de la campagne JOIDES 10, comprend des especes Albiennes et Senoniennes, certaines deja connues din le sud-est des Etats Unis: Cytherella aff.

TL;DR: In this article, the type section of the marly Daliyya Formation was examined for planktonic foraminifera and ostracods, and the coexisting assemblages of the upper part of the Helvetoglobotruncana helvetica total range zone and of the Cythereis rawashensis kenaanensis assemblage zone indicate that this succession is middle Turonian in age.

TL;DR: Krassilov et al. as mentioned in this paper developed a framework for future studies of the Cretaceous Volcanogenic deposits that occur in a broad belt along the Pacific margin.
