World heritage nature at Stevns

The main reason for Stevns Klint being included on UNESCO’s world heritage list was actually a thin layer of fish clay. Special focus was also placed on the geologic record that documents key events in the Earth’s history, as well as there being physical evidence of meteor impacts and the major changes caused by them, for example, the mass extinction of the dinosaurs that made way for mammals.

This mass destruction was caused by a meteor impact 66 million years ago that had a catastrophic global impact. Only about 40% of all Earth’s animals and plants survived the disaster, and the yellowish-white chalk layer over the fish clay tells all about it.

Stevns Klint is the best place in the world to experience this dramatic part of history because the signs of the meteor impact and the major changes that followed are so evident at the cliff.

What is fish clay exactly?

The fish clay is the clearest evidence of the meteor impact that wiped out more than half of Earth’s animals and plants. The fish clay at Stevns Klint contains large amounts of the rare chemical element iridium, which originates from the asteroid that struck Earth 66 million years ago – just at the time when dinosaurs became extinct. So, it was something of a crisis Earth experienced back then, but we humans are evidence of just how strong life is. After a brief respite in Earth’s history, the yellowish-white chalk in Stevns Klint shows that life made a strong comeback!

The dark lines that divide the upper and lower part of Stevns Klint are fish clay, which testifies to the extinction of the dinosaurs, plants and other animals 66 million years ago. You cannot see the fish clay everywhere on the cliff because the lower part of the cliff is hidden beneath the sea in some places.
