متن کاملIterative evolution of digitate planktonic foraminifera
—Digitate shell morphologies have evolved repeatedly in planktonic foraminifera throughout the Cretaceous and Cenozoic. Digitate species are usually rare in fossil and modern assemblages but show increased abundance and diversity at times during the Cretaceous and middle Eocene. In this paper we discuss the morphology and stratigraphic distribution of digitate planktonic foraminifera and establ...

متن کاملCalcium isotope (Î ́44/40Ca) variations of Neogene planktonic foraminifera
[1] Measurements of the calcium isotopic composition (dCa) of planktonic foraminifera from the western equatorial Pacific and the Indian sector of the Southern Ocean show variations of about 0.6% over the past 24 Myr. The stacked dCa record of Globigerinoides trilobus and Globigerina bulloides indicates a minimum in dCasw (seawater calcium) at 15 to 16 Ma and a subsequent general increase towar...
