A pulse of the Earth: A 27.5-Myr underlying cycle in coordinated geological events over the last 260 Myr

[Display omitted] •Ages of 89 major geological events during last 260 Myr.•Fourier analysis shows spectral peak at 27.5 Myr.•A significant shorter period of ~ 9 Myr to 10 Myr.•Global geologic activity in pulses with an underlying ~ 27.5-Myr cycle. We performed spectral analyses on the ages of 89 wel...
