Danian Stage

 

the upper stage of the Cretaceous system (period). This stage was identified in 1846 by the Swiss geologist E. Desor in Denmark and is composed of limestones with sea urchins and other fossils usual in Cretaceous deposits. The argillaceous and marly rocks of the Danian stage contain fauna similar to that of overlying Paleogene deposits. Because ammonites, belemnites, and Globotruncana characteristic of the Cretaceous are absent in the Danian stage, many scientists assign it to the Paleogene system. Deposits of the Danian stage are widespread in Western Europe, North Africa, the Crimea, the Caucasus, and the trans-Caspian region.
