The K–T boundary strata north of Korsnæb, Stevns Klint, Denmark – evolution and geometry revealed in a long, horizontal profile

A 460-meter-long profile of the Cretaceous–Paleogene (K–T) boundary strata at Stevns Klint, Denmark, reveals unprecedented details about the stratigraphy, geometry, and paleotopography of this globally significant geological section. The profile, originally measured by Professor A. Rosenkrantz in 1944, was rediscovered in 2021 and provides critical insights into the boundary strata's evolution, which marks one of Earth's most profound mass extinctions. This coastal section, adjacent to a limestone quarry, showcases fine exposures of lower Danian bryozoan mounds and is partially covered by beach ridges composed of flint rubble. The study underscores the scientific and educational value of Stevns Klint while also highlighting its vulnerability to quarrying activities.
