The Working Group proposed to place the GSSP for the base of the Eocene Series in the Dababiya Section near Luxor in Upper Egypt. The GSSP is located at the base of the Carbon Isotope Excursion which has been selected as the criterion for the recognition of the Paleocene/Eocene boundary in 2002. The proposed boundary section has a good chemostratigraphic (stable isotopes) and biostratigraphic record. The “Benthic Foraminiferal Extinction Event” and the peculiar planktonic foraminiferal and calcareous nannoplankton assemblages linked to the Paleocene Eocene Thermal Maximum are well represented in connection with the Carbon Isotope Excursion. The proposal for this GSSP was accepted by the Voting Members of ISPS and ICS. Finally, it was ratified by IUGS. A complete documentation of the proposed GSSP and the official publication by Aubry et al. (2007) was published in Episodes.
