Introduction:
This supplement contains the image maps generated for each time period, but showing
discrete ranges of Mg/Ca ratios. Also included are histograms of the Mg/Ca ratios from
each individual electron microprobe images (Mg/Ca data is presented in non-normalized
ratios and log-transformed). A figure showing the modeled data compared to actual data is
also included. A figure illustrating that there is no systematic difference between the
arithmetic mean and harmonic mean in a subset of samples. Two tables that contain the
statistics for all samples (lognormal and log-transformed) for each individual sample
(Table S1) and for the pooled data sets for each time period (Table S2).
