This 1977 book shows the positions of the major continental areas during the past 220 million years as four series of computer-drawn maps. All the maps are based on quantitative geophysical or topographic information: paleomagnetic pole positions, ocean floor magnetic anomalies, and best fits of the continental margins.

This 1980 book shows the positions of the major continental areas during the past 560 million years as four series of computer-drawn maps, which provide a framework on which a wide variety of data may be plotted. Cylindrical equidistant and Lambert equal-area polar projections are used, with a thirty-degree latitude-longitude grid.
