The Role of Geomagnetic Field Intensity in Late

1 Introduction. The apparent spacing of mass extinction events at long (~26 Ma) repeat times (e.g., Raup & Sepkoski, 1986), and the supposed role of geomagnetic polarity reversal in extinction (e.g., Raup, 1985), has received intermittent attention over the last 50 years, since early studies of Quaternary radiolarian evolution and polarity reversal in deep‐sea sediments (Hays, 1971).
