Fig. 7. Comparison of the appearance and extinction rates of radiolarians in the eastern equatorial Pacific during the last 17 Ma with a generalized benthic foraminiferal oxygen isotope curve and tectonic events.

The isotope curve has been updated to the ATNTS 2004 (Ogg and Smith, 2004) through paleomagnetic correlation provided by Barton and Bloemendal (1986). The isotope events are after Miller et al. (1991) and Barron and Baldauf (1990).
