Late Cretaceous Lithoevents in the Bohemian Cretaceous Basin, Czechoslovakia

Cretaceous Research, 1991
Abstract Facies evolution and vertical changes within the Late Cretaceous sequence of the Bohemian Cretaceous Basin reveal fluctuations of intra- and extrabasinal circumstances. Evidence of periodic oscillations is recognized and two categories of aperiodic event indications are distinguished according to their significance and lateral persistence ...

Migration of a Late Cretaceous fish

Nature, 2003
Late Cretaceous sediments from the Western Interior of North America yield exceptionally well preserved fossils that serve as proxies for the rapidly changing climate preceding the Cretaceous/Tertiary boundary (about 67-65 Myr ago). Here we reconstruct the ontogenetic history of a Maastrichtian-age fish, Vorhisia vulpes, by using the carbon, oxygen and
