TL;DR: In this paper, the authors defined Twenty shallow benthic zones (SBZ) in the time span ranging from the base of the Paleocene up to the Eocene-Oligocene boundary.

TL;DR: Bybell et al. as discussed by the authors found that the larger foraminifer turnover (LFT), which marks the base of the Ilerdian stage, may be related to the Late Paleocene Thermal Maximum (LPTM), or be at least nearly coeval with that climatic event.

TL;DR: The GSSP for the base of the Lutetian Stage (early/middle Eocene boundary) is defined at 167.85 metres in the Gorrondatxe sea-cliff section (NW of Bilbao city, Basque Country, northern Spain; 43o22'46.47" N, 3o 00' 51.61" W). This dark marly level coincides with the lowest occurrence of the calcareous nannofossil Blackites inflatus (CP12a/b boundary), is in the middle of polarity Chron C21

TL;DR: In this article, the Pyrenean Eocene outcrops display sedimentary successions that offer the rare opportunity to analyse the Ypresian/Lutetian boundary interval in almost continuous sections and in very different settings.

TL;DR: The Ilerdian stage was defined by Hottinger and Schaub as mentioned in this paper to accommodate a significant phase in the evolution of larger foraminifera not recorded in the northern European basins, and has since been adopted by most researchers working on shallow marine early Paleogene deposits of the Tethys domain.
