N2 - Quantitative planktonic foraminiferal analyses of L Miocene sections reveal a hiatus encompassing part of foraminiferal Zones N6 to N7 marking the extinction of Oligocene faunas that survived into the Early Miocene. This faunal event is marked by a cooling reflected in the O isotope record and appears to mark the introduction of cool Antarctic bottom water into the Pacific basin due to the opening of the Drake Passage that allowed deep circum-Antarctic circulation by about 22-25 Ma.-from Author
