Abstract

Outcrops of the upper part of the Zumaya-Algorta Formation at Bidart and Hendaye (France) and Zumaya (Spain) yielded diverse nannofloras of Tethyan aspect that allow recognition of the uppermost Campanian and Maastrichtian nannofossil Zones/Subzones 22C to 26 of the standard succession of Sissingh (1977) and Perch-Nielsen (1985). The anomalous distribution of Reinhardtites levis in this area made it impossible to recognise the base of Zone CC24, while the rarity of Nephrolithus frequens in the uppermost Maastrichtian makes Micula murus and Micula prinsii better markers at this level. Correlation of sections based on nannofloras and lithostratigraphy are in agreement.
