  • We find that the marine 87Sr/86Sr record shows a significant periodicity of m.yr. The 87Sr/86Sr record is out of phase with a 62 (±3)-m.yr. periodicity previously reported in the record of marine animal diversity. These periodicities are close to 58 (±4)-m.yr. cycles found for the number of gap-bounded sedimentary carbonate packages of North America. We propose that these periodicities reflect the operation of a periodic “pulse of the earth” in large-scale earth processes. These may be linked… CONTINUE READING
