Comment on "Major Australian-Antarctic Plate Reorganization at Hawaiian-Emperor Bend Time"

Whittaker et al . (Reports, 5 October 2007, p. 83) presented reconstructions for Australia and Antarctica showing a change in relative plate motion ∼53 million years ago, coincident with an inferred major global plate reorganization. This comment addresses problematic areas in their assumptions and...

Description
Summary:Whittaker et al . (Reports, 5 October 2007, p. 83) presented reconstructions for Australia and Antarctica showing a change in relative plate motion ∼53 million years ago, coincident with an inferred major global plate reorganization. This comment addresses problematic areas in their assumptions and the geological consequences of their reconstructions.
