(Table 1) Planktonic foraminiferal abundance at DSDP Site 94-606

A "total fauna" curve (Ruddiman, 1971; doi:10.1130/0016-7606(1971)82[283:PSITEA]2.0.CO;2) shows that surface water overlying DSDP Site 606 (central North Atlantic Ocean) cooled suddenly at 3.1 Ma, within the Mammoth paleomagnetic reversed interval. At that time, Globorotalia puncticulata,...
