Figure 3. Trajectory of the South Tasman Rise with respect to Antarctica (J.-Y. Royer, unpubl. data). Because Antarctica has remained stable relative to the South Pole since the Cretaceous (e.g., Muller et al. 1993; DiVenere et al., 1994), it also shows the paleolatitudes of the STR. The close correspondence between the hot spot trace (dashed line) and the trace with Antarctica fixed (solid line) adds confidence to the interpretation (ages after Cande and Kent [1995] magnetic reversal time scale; magnetic chrons in parentheses).
