The Lower-Upper Cretaceous and Cretaceous­Tertiary boundaries in China

Abstract

The Cretaceous rocks of China are represented by both marine and nonmarine facies. Correlation of the marine sequences is based in particular in ammonites, foraminifera, rudists and palynomorphs, and that of the nonmarine sequences on reptiles (including dinosaur eggs), fish, bivalves, ostracodes, conchostracans, insects, plants, charophytes and palynomorphs.
