Comment:
Placement of previously published bulk and benthic foraminifera stable carbon isotope data for Upper Cretaceous and Lower Paleogene sediment at DSDP Site 577 according to composite depth scale and an updated time scale (Westerhold et al., 2008, 2012). Isotope, CaCO3 and size fraction data were reported by Zachos et al. (1985), dataset doi:10.1594/PANGAEA.802433. DEPTH, sediment is the depth [mbsf] reported by Zachos et al. (1985). Note that depths for CC samples are not consistent with core logs.
