Discussion of some recent papers on ancient continental configurations reconstructed from paleomagnetic evidence

In theory it is possible now to reconstruct the ancient continental configurations, both in latitude and in longitude, from paleomagnetic data alone. The papers that have first applied this new method are discussed. At present only the data from Africa and South America seem appropriate for practising the theory. Their configuration (Creer, 1964a) agrees with the well-known continental drift hypotheses. Creer’s ideas on the Upper Paleozoic positions of the Laurasian continents are not shared by the present author
