Sixteen maps are presented illustrating the relative positions of the continents from the Early Triassic to the Recent. The spreading history of the Atlantic and Indian Oceans is based on the plate tectonic models of Sclater et al; Norton and Sclater; and Phillips and Tapscott. The age of the oceanfloor has been plotted using Sclater's data-base of worldwide linear magnetic anomalies.

Mesozoic and Cenozoic paleomagnetic data were compiled and selected for reliability. Pole positions obtained from samples that were insufficiently demagnetized, that were from unstable tectonic areas, or that did not exhibit a primary remanence, were rejected. A global apparent polar wander path (African coordinates) was constructed using these selected paleomagnetic determinations. The position of the magnetic pole for each plate tectonic reassembly was estimated by interpolating along this polar wander path.
