This work summarises the results of ten years of study of the palaeomagnetism and biostratigraphy of Tithonian–Berriasian profiles in the middle Vocontian Basin: at Le Chouet, Le Ravin de Font de Saint Bertrand, Charens, Belvedere (Haute Beaume) and Tré Maroua. This study has thus focussed on the “Calcaires Blancs vocontiens”, a predominantly micritic formation developed locally in microfacies categories SMF 2, SMF 3 and SMF 4. Facies zones FZ 3 and FZ 4 indicate deposition in upper to mid… 
Upper Jurassic–Lower Cretaceous calpionellid zones in the Neuquén Basin (Southern Andes, Argentina): Correlation with ammonite zones and biostratigraphic synthesis

Upper Berriasian chemostratigraphy, clay minerals and calcareous nannofossils of the Barlya section (Western Balkan, Bulgaria): Implications for palaeoclimate and productivity changes, and stratigraphic correlations across the Alpine Tethys
Abstract Upper Berriasian chemostratigraphic, clay mineral and calcareous nanofossil data are presented from a precisely dated hemipelagic section of Barlya (Western Balkan, Bulgaria). The section
Jurassic – Cretaceous boundary record in Carpathian sedimentary sequences
Abstract An integrated study of micro- and nannoplankton distribution, O and C isotopes and palaeomagnetic record of nine Carpathian sections provided a key interpretation tool to characterize the
Reliability of calcareous nannofossil events in the Tithonian–early Berriasian time interval: Implications for a revised high resolution zonation
Abstract The latest Jurassic was a crucial time for calcareous nannoplankton as a major speciation episode took place with the appearance and rapid evolution of several new genera and species,
Berriasian ammonites of supposed Tethyan origin from the type ‘Ryazanian’, Russia: a systematic re-interpretation
Abstract For more than a century, a number of ammonite taxa of supposed Tethyan origin or affinity have been reported from the Berriasian condensed deposits of Russia (referred to as ‘Ryazanian’).
The proposal of a GSSP for the Berriasian Stage (Cretaceous System): Part 2
In part 1 of this work we discussed the possibilities for the selection of a GSSP for the Berriasian Stage of the Cretaceous System, based on prevailing practical methods for correlation in that J/K
First computer-assisted 3D-reconstruction of calpionellid tests (Protozoa incertae sedis) and corresponding section restoration
Abstract Calpionellids are widespread protozoans of Late Jurassic-Early Cretaceous age, typically found in Tethyan pelagic domains and related paleobiogeographic provinces. Their abundance and rapid
A critical look at Tré Maroua (Le Saix, Hautes-Alpes, France), the Berriasian GSSP candidate section
The Tre Maroua site in SE France was recently selected by the Berriasian Working Group (BWG) of the International Subcommission on Cretaceous Stratigraphy (ISCS) as the candidate locality for the
Paleozoic–Mesozoic Eustatic Changes and Mass Extinctions: New Insights from Event Interpretation
The majority of the considered mass extinctions coincided with either interruptions or changes in the ongoing eustatic trends, and it cannot be excluded that such interruptions and changes could have facilitated or even triggered biodiversity losses in the marine realm.
Comments on the geology of the Crimean Peninsula and a reply to a recent publication on the Theodosia area by Arkadiev et al. (2019): “The calcareous nannofossils and magnetostratigraphic results from the Upper Tithonian–Berriasian of Feodosiya region (Eastern Crimea)”

The Jurassic/Cretaceous boundary and high resolution biostratigraphy of the pelagic sequences of the kurovice section (Outer Western Carpathians, the northern Tethyan margin)
Abstract Microfacies and high resolution studies at the Kurovice quarry (Czech Republic, Outer Western Carpathians) on calpionellids, calcareous and non-calcareous dinoflagellate cysts, sporomorphs
New belemnite records from the Mitarai Formation, Tetori Group, Japan: Delimitation of the Jurassic-Cretaceous boundary in the Japanese Islands
Abstract Traditional faunal elements for zoning the uppermost Jurassic‒lowermost Cretaceous stratigraphic interval in Tethyan regions, i.e., ammonites and calpionellids, are either lacking in the
Calcareous nannofossils of the Jurassic/Cretaceous boundary strata in the Puerto Escano section (southern Spain) — biostratigraphy and palaeoecology
Abstract We obtained material from the Puerto Escano section (southern Spain) to study the Jurassic/Cretaceous (J/K) boundary interval. The same samples had already been processed for
A review of magnetostratigraphic results from the Tithonian–Berriasian of Nordvik (Siberia) and possible biostratigraphic constraints
Abstract In this contribution we examine and discuss recently published magnetostratigraphic data from the Nordvik section (north Siberia) around the Tithonian–Berriasian (J/K) boundary, with a
