Analysis of rock and fossil samples collected from James Ross Island, Antarctica
To obtain a global view of climate change, the climatic and evolutionary history of the Southern Hemisphere needs to be integrated into the picture, and an integration of high-latitude change is particularly important. 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.

Data collection:
The analyses were carried out in 2003 using a VG Sector 54 with 5 collectors.
The results were normalized to 0.710248 for NIST987 (old SRM987)
Data quality:
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.
