“…australis was recorded above the Maastrichtian-Campanian boundary at Tercis, while B. miliaris ranged from the uppermost Campanian to the lower Lower Maastrichtian (Tronchetti, 2001). Tronchetti et al (2001) note a change at the Campanian-Maastrichtian boundary from Bolivinoides taxa with four lobes on the suture of the final chambers to specimens with five lobes above the boundary. In this study we have correlated the LO of Bolivinoides australis to approximate the Campanian-Maastrichtian boundary, following Robaszynski Upper Cretaceous biostratigraphy, offshore NW Australia Table 3.…”

Abstract. During the latest Campanian–Maastrichtian the northwestern Australian margin was situated between the cool-water Austral Province to the south and the warm-water Tethyan Province to the north. The transitional nature of calcareous microfossil assemblages on the margin makes application of Tethyan biostratigraphic zonation schemes awkward, as many marker-species are missing or have different ranges. This study presents an integrated uppermost Campanian–Maastrichtian calcareous microfossil zonation based on two Ocean Drilling Program (ODP) holes on the Exmouth Plateau and eight petroleum exploration wells from the Vulcan Sub-basin. The zonation is refined and revised from the previously unpublished KCN (nannofossils), KPF (planktonic foraminifera), KBF (benthonic foraminifera) and KCCM (composite nannofossil and planktonic foraminifera) zonations, which are commonly used for petroleum exploration wells drilled on the northwestern margin. Revision of the zonations has highlighted a major Upper Campanian to lower Upper Maastrichtian disconformity on the Exmouth Plateau, which went largely unnoticed in previous examinations of the ODP material, but had been recorded previously elsewhere on the northwestern margin. The duration of the disconformity in the Vulcan Sub-basin is unclear, since intervals of the succession may be condensed in this area.

“…Three dinoflagellate cysts [2,3,21,22], one calcareous nannofossil [5,7,8,12,25], two benthic foraminiferas [24] and two planktonic foraminiferas [4,6,10,18] show significant biohorizons near the Campanian-Maastrichtian stage boundary (Fig. 2); they have been used to calculate the level where the stage boundary should be located.…”

“…Les foraminifères benthiques, intéressants pour des corrélations européennes, n'ont fait l'objet que d'études restreintes [24]. Deux marqueurs ont été retenus, l'un dans l'évolution du genre Bolivinoides (prédominance d'une forme à cinq lobes sur la dernière loge à un niveau situé sous la limite), l'autre à la disparition de Gavelinella clementiana (d'Orbigny), localisée à la limite d'étage.…”

Definition of a multi-criteria boundary; stratigraphy of the Campanian-Maastrichtian interval of the geological site at Tercis (Landes, SW France). Lithostratigraphy, physicochemical stratigraphy, biostratigraphy, and geochronology of the 77-70 Ma old series bracketing the Campanian-Maastrichtian boundary have been investigated by 70 experts. For the first time, direct relationships between macro-and microfossils have been established, as well as direct and indirect relationships between chemo-physical and biostratigraphical tools. A combination of criteria for selecting the boundary level, duration estimates, uncertainties on durations and on the location of biohorizons have been considered; new chronostratigraphic units are proposed. The geological site at Tercis is accepted by the Commission on Stratigraphy as the international reference for the stratigraphy of the studied interval. To cite this article: G.S. Odin, C. R.

Ils ont caractérisé la lithostratigraphie, la physicochimie, la biostratigraphie et la géochronologie de l'intervalle 77-70 Ma renfermant la limite Campanien-Maastrichtien. Des corrélations directes ont été établies pour la première fois entre macrofossiles et microfossiles, ainsi que des corrélations directes et indirectes entre outils physico-chimiques et biostratigraphiques. L'incertitude liée à ces relations, le principe de combinaison de plusieurs critères pour fixer le niveau de la limite et des estimations de durée ont été considérés ; de nouvelles unités chronostratigraphiques sont proposées. Le site géologique de Tercis est reconnu par la Commission de Stratigraphie comme la référence internationale pour la stratigraphie de l'intervalle examiné.

The Campanian-Maastrichtian boundary has never been formally defined; in addition to a number of other less common uses two current practices exist: they consider the first occurrence (FO) of the boreal endemic key taxon Belemnella lanceolata (belemnite) and the last occurrence (LO) of the oceanic Radotruncana calcarata (planktonic foraminifera). Based on indirect correlation, the boreal FO is distinctly younger compared to the Tethyan LO. The Tethyan section near Dax (Tercis les Bains*, SW France) has been studied in detail for the last eight years by a Maastrichtian Working Group. Physicochemical data and biostratigraphical characterisation on 18 fossil groups have been established. The selected section is exceptionally well located in a key area allowing correlation between the Boreal and Tethyan Realms, western Europe and North America, the oceanic and platform environments, the marine and continental successions. Correlation with regard to historical stratotypes of Charente (France) and Limburg (Belgium and the Netherlands), key sections in the Boreal (mostly Kronsmoor, N. Germany) and Tethyan Realms (mostly Navarra, N. Spain and Gubbio, Apennines) have been studied and discussed. The here-presented boundary point is consistent with the content of historical stratotypes; a rather precise connection with the records in the Apennines and N Germany allows to locate the Tercis boundary in these two areas and, reversely, to correlate stratigraphical information from these areas to the Tercis section near Dax. The new definition was voted and ratified between 1999 and 2001.
