Theme 1: Cretaceous-Paleogene boundary
The Cretaceous Palaeogene boundary (also known as the Cretaceous - Tertiary boundary) is a worldwide marker, which coincides with one of the most conspicuous and abrupt changes in the fauna of the earth.
The localities in Denmark present the boundary in a variety of unique sedimentological successions and are among the most studied in the world.

Eight GeoSites are included in this theme
Stevns Klint (GS 1-1) is the main GeoSite.
Note: Stevns is a key GeoSite within both Theme 1 and 2!
All the other 7 locations within Denmark, which expose the boundary, are supplementary GeoSites to Theme 2. The supplementary GeoSites expose the Cretaceous-Palaeogene boundary in other, generally more micritic facies, than at Stevns, and in some of the locations there is less hiatus at the boundary.
Sites in Northern Jutland
Nye Kløv (GS 1-2)
Kjølby Gaard (GS 1-3)
Bjerre (GS 1-4)
Vokslev (GS 1-5)
Erslev (GS 1-6)
Site in Eastern Jutland
Dania (GS 1-7)
Site in Zealand
Karlstrup (GS 1-8)
At present there is a collective description of the supplementary GeoSites only: se below.
