This study presents element/Ca data collected on Nodosariata, a particular group of foraminifera. The results of this work can potentially expand the applicability of foraminiferal proxies to the Permian, with important implication for the pale oceanographic and modeling communities.

Short summary
We analyzed Mg / Ca and other El / Ca (Na / Ca, B / Ca, Sr / Ca and Ba / Ca) in Nodosariata. Their calcite chemistry is markedly different to that of the other calcifying orders of foraminifera. We show a relation between the species average Mg / Ca and its sensitivity to changes in temperature. Differences were reflected in both the Mg incorporation and the sensitivities of Mg / Ca to temperature.
