  • Explanation of terms: δ18O, oxygen isotope records used as proxy for climate change; diatom, diatom species diversity (Neptune database); rock, total number of fossiliferous marine formations as downloaded from the Paleobiology Database; st. dur., geological stage duration; the latter was included as a non-optional predictor in all models on order to account for the potentially biasing effects of unequal Caenozoic stage durations. Based on data from Marx & Uhen (2010).
