The bare rock floor of a log cabin in Germany’s Eifel Hills defines, by international agreement, the boundary between Lower and Middle Devonian rocks throughout the world. This marks the beginning of the age in Earth history that will forever be called the Eifelian.

From the first fumbling attempts in antiquity, it took humanity 2 300 years to comprehend geological time.
Fossil fuel without fossils
Europe’s largest impact crater from an asteroid was created in Sweden’s Dalarna region 377 million years ago. The echoes of this energy release can still be heard.
