Figure 6. Compilation of DSDP/ODP isotope data from Albian to Maastrichtian (from Huber et al., 1995; Fassell and Bralower, 1999; Stott and Kennett, 1990; Barrera and Huber, 1990; Barrera, 1994; Barrera and Savin, 1999). Dashed lines connecting benthic foraminifer data = unconformities, solid symbols = benthic foraminifer, open symbols = planktonic foraminifers. CTBI = Cenomanian/Turonian Boundary Interval.
