Relevance of Cretaceous Volcanic Activity to CRERIntense, global volcanic activity with peaks in the Aptian-Albian and Campanian-Maestrichtian may have had significant effects on sea level changes, paleobathymetry and circulation of the Pacific Ocean, chemistry of the atmosphere and hydrosphere and global climates, and the distribution and evolution of faunas and floras.

Cretaceous Stage Boundaries — ProposalsA unified scale of Cretaceous stages has been generally accepted for a long time. However, the earliest stage, the Berriasian, is often replaced by the Ryazanian, reflecting the particular difficulties of correlating between the Tethyan and the Boreal Realms around the Jurassic-Cretaceous boundary.

The advantage of the sequence-stratigraphic approach is that unlike transgressions and regressions of the shoreline or changes in paleobathymetry, the development of prominent sequence boundaries is relatively insensitive
