Fig. 4. The (i13C of F. wuellerstorfi and closely related cibicidoids is plotted versus (i13C rc02 of bottom water.
The I: I relationship including a ± 0.2 %0 reliability range as commonly used by paleoceanographers is given for
comparison (open circles, dead specimens; full dots, Rose Bengal stained (live) specimens).
