The Ordovician global bio-events appear to have been synchronous with major eustatic fluctuations of the sea-level. However, not all such fluctuations led to noteworthy extinctions.

There exists no evidence for a catastrophic change at the Frasnian-Famennian boundary. Instead, the documented changes occurred over a time period of approximately 6 to 8 million years.

These events, clearly expressed in lithology and fossil content, are probably caused by eustatic sea level changes. They are demonstrated in a similar manner in many other areas, even distant and of different tectonic regimes.
