Figure F10. Leg 210 timescale and primary calcareous microfossil datums for the Cenozoic and Cretaceous. A. 0–25 Ma. Forams = foraminifers, Nannos = nannofossils. T = top (last occurrence), B = bottom (first occurrence). TA = top acme. Foraminifer datums are underlined. S = sinistral, D = dextral. Datum ages (Ma) are in parentheses. B. 20–45 Ma. C. 40–65 Ma. D. 60–85 Ma. E. 80
