一个普遍存在的~ 6200万年的周期波动叠加在化石biodiversity的一般趋势上
An ubiquitous ~62 Myr periodic fluctuation superimposed on general trends in fossil biodiversity
摘要：
6200万年的周期叠加在化石生物多样性的其他长期趋势上。这个循环可以在基于Sepkoski纲要、古生物学数据库和化石记录2的海洋数据中辨别出来。海平面/沉积物的变化也存在这种信号，但比生物多样性本身的变化要弱得多。一个显着超过19个先前确定的中生代质量喷发发生在下降阶段的6200万年周期。如果在采样标准化生物多样性数据中出现这种信号，那么它很可能不是一种采样人为因素，而是海平面变化的结果，或者是两者的某种共同原因的额外影响。在这两种情况下，为什么这两种变化都有规律，这很有趣。
英文摘要：
A 62 Myr periodicity is superimposed on other longer-term trends in fossil biodiversity. This cycle can be discerned in marine data based on the Sepkoski compendium, the Paleobiology Database, and the Fossil Record 2. The signal also exists in changes in sea level/sediment, but is much weaker than in biodiversity itself. A significant excess of 19 previously identified Phanerozoic mass extinctions occur on the declining phase of the 62 Myr cycle. appearance of the signal in sampling-standardized biodiversity data, it is likely not to be a sampling artifact, but either a consequence of sea-level changes or an additional effect of some common cause for them both. In either case, it is intriguing why both changes would have a regular pattern.
