..., 2008 ). The second change marks the Danian–Selandian boundary (DSB), which was originally defined as the base of the Lellinge Greensand in Denmark and is now defined as the base of the Itzurun Formation in Zumaia, Spain, its Global Boundary Stratotype Section and Point (GSSP), dated at 59.9 Ma...

... in the basal metres of the Itzurun Formation, and the second one is located c . 10 m lower at the transition from limestone to limestone–marl couplets at the top of the Danian Aitzgorri Limestone Formation. The latter lithological change and carbon isotope excursion correlate biostratigraphically...

... in the Pyrenean basin during the Late Cretaceous–early Paleogene ( Baceta, 1996 ; Pujalte et al., 1998 ). The studied interval encompasses the uppermost 3 m of the Paleocene (Itzurun Formation; see Baceta et al., 2004 ) and the lowermost 7 m of the Eocene (Eocene Flysch); samples are spaced at 5–10 cm intervals...

The LDE beds at Gebel Qreiya resemble the organic-rich dark brown layers at the PETM in the Esna Shale Formation ( Speijer, 2000 , 2003a ; Knox et al ., 2003 ), but no extinction of benthic foraminifera is observed during the LDE (e.g. Speijer, 2003a...
