Figure 5. Carbon and oxygen isotope values of planktonic and benthic foraminifers from the upper Paleocene at Sites 527, 690, and 865 (Kennett and Stott, 1991; Bralower et al., 1995; Thomas and Shackleton, 1996; Zachos and Rea, unpubl. data) plotted vs. age. Planktonic foraminifer data (upper two boxes): diamonds = Site 865, circles = Site 690, crosses = Site 527. Benthic foraminifer data (lower two boxes): diamonds = Site 690, squares = Site 527, circles = Site 865.
