DINOCYST BIOSTRATIGRAPHY OF THE UPPER CRETACEOUS OF NORTHERN SIBERIA

Abstract

A stratigraphic chart is developed of the Upper Cretaceous deposits of northern Siberia based on dinocysts. It covers the period from the Upper Cenomanian to the Maastrichtian, including 15 biostratigraphic units (beds with characteristic assemblages or local zones), and is correlated with the inoceram zonation. © Pleiades Publishing, Inc. 2006.
