Records of benthic foraminifera from North Atlantic DSDP Site 607 and Hole 610A indicate changes in deep water conditions through the middle to late Pliocene (3.15 to 2.85 Ma). Quantitative analyses of modem associations in the North Atlantic indicate that seven species, Fontbotia wuellerstorfi, Cib...
