Determination of the relative positions of continents from paleomagnetic data

It has been argued that it is not possible to determine the relative positions of continents from paleomagnetic data because of the uncertainty with regard to longitude. This is true only if the continents have been drifting continuously relative to one another throughout the period in which the pole has wandered, which apparently is the whole of geologic time. The classical theories of continental drift picture a giant continent splitting up into several parts at a comparatively late stage in the history of the earth. If the usual assumptions in the interpretation of paleomagnetic data are valid, it must be possible from paleomagnetic data to prove or disprove this hypothesis and to establish uniquely the ancient relative positions of the now separated continents.
