傅立叶分析的幅度和时间的中生代质量波动（MEs）表明，许多周期性声称在其他分析是没有统计意义的。此外，我们表明，与太阳系的银河系平面振荡的周期性是太不规则的傅立叶周期图中的窄峰。这使我们得出结论，除了少数可能的重大事件外，ME的天文原因在很大程度上可以排除。
A Fourier analysis of the magnitudes and timing of the Phanerozoic mass extinctions (MEs) demonstrates that many of the periodicities claimed in other analyses are not statistically significant. Moreover we show that the periodicities associated with oscillations of the Solar System about the galactic plane are too irregular to give narrow peaks in the Fourier periodograms. This leads us to conclude that, apart from possibly a small number of major events, astronomical causes for MEs can largely be ruled out.
