To assist this integration, we applied the methods of palynology and Sr isotope stratigraphy to confirm and refine the numerical ages of the sedimentary succession within the Antarctic Peninsula. We were able to establish a precise chronology using strontium isotope stratigraphy. Various calcitic and aragonitic fossil shells collected from these strata proved to be exceptionally well preserved and strontium isotope ratios obtained from them have provided some of the most accurate ages yet obtained for Cretaceous sedimentary rocks in the Southern Hemisphere. Revision of the age of the succession dramatically changed the accepted ages, by half a Stage, from Barremian-to-Santonian to Aptian-to-Coniacian.
