Paleogeography Through Geologic Time
This presentation uses some of the same paleogeographic and plate-tectonic reconstructions as shown on the Regional Paleogeographic Views page except that the maps and globes are organized by geologic period. The Regional Views link presents the maps and globes by region.
UPDATE!! Revised maps!! Additional maps!!
PLEASE NOTE: Some of the maps on this page are relatively old and are presented here at their full resolution. Newer maps are available at
