The Cretaceous-Paleogene Boundary in Denmark

This is a neat idea--slather large amounts of resin on the outcrop at Stven's Klint, in Denmark and then pull of the resulting 'peel' to make a sample of the Cretaceous-Paleogene boundary section. In this slab (taken by folks at Bremen University), the Cretaceous is the lower white chalk below the rusty orange bed, the K/Pg boundary is the orange bed and the basal Paleogene starts with the greenish clay beds that gradually shift back into white Paleogene chalk.Those are the tips of our boots for scale.
