Ranges of Globorotalia menardii menardii, Gr. menardii flexuosa and Globoquadrina hexagona at time of climatostratigraphic intervals representing oxygen-isotope stages 5-1 are determined by study of dozens of Late Quaternary sediment cores involving constructing paleotemperature curves from planktic foraminifera and oxygen isotope curves for their shells, as well as radiocarbon dating. Gr. menardii flexuosa and Gq. hexagona disappeared about 27-25 ky ago from the subtropical and tropical Atlantic and about 18 ky ago from the equatorial area.
Parentheses indicate least reliable determinations in cores with signs of re-deposition or with non-indicative paleoclimatic curves.
