"During long periods of the Earth's history, we've had small tidal ranges. But in the Late Silurian and Early Devonian, they seem to have been large in some parts of the world.

The Devonian period, which lasted from about 419 million to 359 million years ago, culminated in a mass extinction event. During the Devonian, life on dry land was just getting started, and plants ...

Earth’s marine species, especially those at the tropics, were in trouble again about 419 million to 365 million years ago. This series of mass extinctions during the Devonian period eventually ...

The primary cause behind the Devonian and Ordovician mass extinction events is not fully understood, but both of them have also been linked to the depletion of Earth's ozone layer.
