Supplementary Table 11: Compilation of newly analysed bulk carbonate carbon and oxygen isotope ratio data and published analyses. Most of the data are derived from aggregate bag samples, for with a depth range is given and an average depth in meters is calculated and where possible, an interval bag number matching the record of Copestake and Johnson, 2014 is given. In the interval from 1340 to 1410 m depth, samples were taken from registered specimens with precisely know depths. Interval bag data for this section were therefore not considered for the compilation and shifted to the bottom of the table. Last 12 data entries are from clearly diagenetic carbonate and/or siderite.
