...Fig. 1 Geologic map of the Upper Cretaceous - Lower Eocene outcrops in the Zumaia area and schematic Paleocene paleogeographic map of western Europe [from Schmitz et al. , 2011 ] I: Zumaia-Algorri Formation (Middle-Late Maastrichtian); II: Aitzgorri Limestone Formation (Danian); III: Itzurun...

..., 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 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...

... radiation of the important calcareous nannofossil group, fasciculiths” ( Schmitz et al., 2011 , p. 220), which is established in a range slightly exceeding 1 m. In fact, the GSSP is merely the base of the marl Itzurun Formation; that is, a lithological event indicative of the replacement of carbonate...

... excursion is situated 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...

... ). The basin was characterized by neritic to upper bathyal marl and shale deposition of the Dakhla Formation (Fm.) in a basin generally deepening to the northwest ( Speijer, 2003a and references therein). Micropalaeontological data indicate Danian and Selandian palaeodepths ranging from 70–150 m at Gebel Duwi...
