Owing to the fact that the principal investigator died before data were able to be archived, the only available data are in the form of the referenced paper, which is available as a PDF download. From the referenced paper: Australia-Antarctica reconstructionists find the piece marked 'Tasmania' difficult to fit into their jigsaw puzzles. Most agree that 55 million years ago Tasmania was not far north of North Victoria Land. This first step backwards in the reconstruction process, when the southeast Indian Ocean is closed by reversal of its spreading history, is well-constrained by dated oceanic magnetic anomalies and prominent fracture zones south of Tasmania. Yet by Cretaceous times, most Gondwanan reconstructions have removed Tasmania to the east of North Victoria Land.
