Introduction
[This supporting information includes a supporting Table S1 with sediment trap samples
and the number of individuals per species from the designated trap samples as well as a
supporting table S2 with the LA-ICP-MS Mg/Ca data set used in this study. Also, we
added a supporting Figure showing calculated calcification depth of crust, ontogenetic
and total Mg/Ca of the calcite, using species specific calibrations.]

Figure S1. Calculated calcification depth for P. obliquiloculata and G. scitula, using crust, ontogenetic and
average shell Mg/Ca concentrations from one specific sediment interval, MOZ4 A16 and MOZ4 A19
respectively. Species specific calibrations from Anand et al., 2003 were used to calculate calcification
temperatures [P. obliquiloculata: Mg/Ca=0.328 exp(0.09 T); G. scitula using the calibration for G. hirsuta:
Mg/Ca=0.409 exp(0.09 T)]. Squares indicate calculated calcification depth, based on average crust, onto
and total Mg/Ca for the different chambers.
