Samples are ordered by depth within each segment of the inter-hole splice. Depths below sea floor on the CSF-A scale are converted to composite depths on the CCSF scale according to offsets given in the affine table in Ref [ 52 ]. Ages are calculated within the age-model tie points indicated and as given in S1 Table . Sample weights and Pulleniatina coiling counts of 50 specimens are reported. In the intensive study windows indicated, samples were split and the absolute number of sinistral and dextral specimens recorded; these data were substituted for earlier counts, and those counts discounted, in these windows only.
