... in the northern sector of the Antarctic Peninsula on Vega Island has been proposed, yet current temporal resolution of these strata prohibits direct testing of this hypothesis. To not only test for the existence of a K/Pg boundary on Vega Island but also provide increased age resolution for the associated...

Stratigraphical correlations between northern James Ross Island and Vega Island, positions of samples, and the ranges of some key fossil taxa. Vertical scale (100-m intervals on left) is a composite one for the entire region (Crame et al. 1996). Based on Crame and Luther (1997, fig. 2) with stage boundaries revised from data presented herein. CE.=Cenomanian, SANT.=Santonian. Precise biostratigraphic correlations between localities D.8409 and DJ.685 (southeastern James Ross Island; fig. 1) have yet to be established.
