Abstract The Second International Symposium on Cretaceous stage boundaries held in Brussels from September 8-14 1995 reached a preliminary agreement on the definition of the base of the Cenomanian stage as the first occurrence of the planktonic foraminiferan Rotalipora globotruncanoides Sigal, with a section at Mont Risou near Rosans, Drome, SE France as the global reference section, Sigal, with a section at Mont Risou near Rosans, Drome, SE France as the global reference section, where the first occurrence of R. globotruncanoides lies 36 m below the top of the Marnes Bleues as defined by a zero datum limestone at the base of the succeeding unit. The succession yields ammonites, inoceramid bivalves, nannofossils and planktonic foraminifera that provide a series of marker levels across the boundary, while an ornate δ 1 3 C curve provides a geochemical marker that can also be recognized in NE England and Italy. Proxies for R. globotruncanoides are: the first appearance of Mantelliceras mantelli and other ammonites of the mantelli Zone at -30 m, the first occurrence of the nannofossil Calculites anfractus , the first occurrence of the planktonic foraminiferan Rotalipora gandolfii and the last occurrence of the planktonic foraminiferan Rotalipora ticinensis at -40 m, and the last occurrence of the nannofossil Staurolithites glabra at -12 m. Ammonite, inoceramid, nannofossil and planktonic foraminiferan occurrences are documented, a systematic account of the ammonites, and full range data and nomenclature of the nannofossils provided. Previous alternative definitions of, and boundary stratotypes proposed for the base of the Cenomanian are critically reviewed and compared with the Risou section.

Abstract The Early–Late Cretaceous transition (late Albian–early Cenomanian; ∼100 Ma) witnessed marked environmental changes and a deep reorganization of the marine fauna. The impact of these environmental and biotic changes on Tethyan marine vertebrates is poorly understood, due to a fragmentary fossil record. Here we report upper Albian marine vertebrate remains, including a partially articulated plesiosaurian skeleton, from a fossiliferous glauconite-rich bed in the Alpes de Haute-Provence, F...

Abstract A Neo-Tethyan upper Albian–Turonian (hemi-)pelagic carbonate succession (Sarvak Formation), accessible in outcrop in the Zagros, SW Iran, was investigated using sedimentology, microfacies analysis, planktonic foraminifera biostratigraphy, and carbon-isotope stratigraphy. The succession contains six biozones including Thalmaninella (Th.) appenninica , Th. globotruncanoides , Rotalipora cushmani, Whiteinella archaeocretacea, Helvetoglobotruncana Helvetica , and Marginotruncana schneegansi...

Abstract A comprehensive taxonomic account of fourteen ammonite species from the upper Albian succession of the Cauvery Basin, south India is presented. They belong to the genera/subgenera Gaudryceras , Anagaudryceras , Tetragonites , Puzosia ( Puzosia ), Puzosia ( Bhimaites ), Desmoceras ( Desmoceras ), Desmoceras ( Pseudouhligella ), Stoliczkaia ( Stoliczkaia ) and the heteromorphs Anisoceras and Mariella . Most of these ammonite species are cosmopolitan and well-known, especially from the wes...

Abstract The transition of post-obduction Neotethyan contraction to Eo-Alpine (“Austroalpine”) nappe stacking that took place during the Early Cretaceous is an important event in the Cretaceous history of the Alpine-Carpathian-Dinaridic orogenic system. The Transdanubian Range (TR) in Hungary has been shown to have been impacted by both events. Dating of this transition has proved to be difficult; several interpretations were published during the last decades. Uniquely exposed in and around the ...

Abstract During the Albian and Cenomanian, the Earth underwent profound climatic and oceanographic changes that were recorded in sedimentary successions on a global scale. Carbon isotope records spanning this time interval have been established in the western Tethys, eastern Pacific and North Atlantic Oceans, but not yet in the eastern Tethys Ocean. In this paper, we present biostratigraphic, chemostratigraphic and cyclostratigraphic characteristics of the uppermost Albian–lowermost Cenomanian i...

Abstract Ever since the introduction of the Cretaceous System, nearly two centuries ago, the terms ‘mid-Cretaceous’ and ‘middle Cretaceous’ keep appearing in the literature, implying a three-fold division rather than the more generally accepted two-fold division of the system/period. The frequent and persistent use of these informal terms proves that they fulfil a need in stratigraphic communication; consequently, formalisation of a middle series/epoch of the Cretaceous System/Period is justifie...

A condensed succession at Annopol is of key importance for the mid-Cretaceous palaeontology and palaeobiogeography in Poland. Here, the planktonic and benthic foraminifera from the Albian and Cenomanian intervals are studied. The local foraminiferal record is strongly influenced by burrowers. On the one hand, piping down of the foraminiferal tests through burrows disturbed the original succession, for example by introduction of the Cenomanian foraminifera into the Albian phosphorite horizon. On ...
