  • Recently published diatom biochronologies provide accurate (to 0.1 m.y.) determination of the ages of appearances and disappearances of planktonic diatoms during the past 18 m.y. in the equatorial Pacific, North Pacific, and Southern Ocean. Comparisons of these records reveal the age of evolutionary appearance and extinction of species and their region of origin. Extinct planktonic diatom species have a mean longevity of 3.4 ± 2.8 m.y. (SD, n = 53) in the equatorial Pacific, 2.5 ± 2.1 m.y. (n… CONTINUE READING
