Temperatures were converted from the Mg/Ca data via the calibration equation of ref. 66. Daggers () denote a distinct G. truncatulinoides group. BSD = Bulk shell density and ACD = calcification depth. Refer to the Methods for a complete description of the parameters. The data are available also at Zarkogiannis et al.82.
