This article shows that Gauss-Vanick (GV) analysis of this diversity data detrended with a cubic also strongly signals a 62-million-year periodicity. Furthermore, it was found that neither GV analysis nor Fourier transform analysis of the nondetrended data leads to any statistically significant periodicity. The results show that the two techniques are equivalent.
