TOC and CaCO3 profiles are compilations of published data by ref. 13. Data for δ13Ccarb are from ref. 13; data points enclosed by the dotted line are δ13Ccarb values of samples with anomalous Sr isotope ratios affected by selective diagenesis17. The Os isotopic data are from ref. 11 and this study and the Pb isotopic data are from this study.
