Calibration of Holocene size patterns with environmental parameters and comparisons with Cenozoic paleoproxy data show a consistently positive correlation between test size and surface-water stratification intensity. We infer that the observed macroevolutionary increase in test size of planktic foraminifera through the Cenozoic was an adaptive response to intensifying surface-water stratification in low latitudes, which was driven by polar cooling.completedInvertebrate paleontologyadaptive radiationassemblagesbiogeographybiologic evolutionCenozoicDeep Sea Drilling ProjectForaminiferaHoloceneInvertebrataisotope ratiosisotopesmarine environmentmarine sedimentsmicrofossilsmorphologyNeogeneO-18/O-16Ocean Drilling Programoxygenpaleoclimatologypaleoecologypaleotemperatureplanktonic taxaPleistocenePlioceneProtistaQuaternaryreconstructionsea-surface temperaturesedimentssizestable isotopesTertiarytestsEnglishgeoscientificInformationapplication/pdfunknownSEDIS Publication Catalogue
