Integrated stratigraphy of Lower Cretaceous sediments (Ryazanian-Hauterivian) from North-East Greenland

摘要

The reconstruction of past climates and oceanography requires a solid stratigraphic framework ideally applicable on a global scale. The earliest Cretaceous, however, was a time of strong faunal provincialism, making supraregional correlation of biostratigraphical zonations difficult. The step-by-step correlations between neighbouring provinces/subprovinces that are commonly utilized bear the risk of loosing accuracy in every step.
