Virtual reality reconstructions illustrating the plate tectonic development of the ocean basins and continents, as well as the changing distribution of land and sea during the past 1100 million years.
The Paleogeographic Atlas Project http://pgap.uchicago.edu/
Global paleogeography and paleoclimates, with emphasis on the Permian and Jurassic. Climate-sensitive sediment and fossil plant distributions are shown on detailed paleogeographic maps, enabling determinations of global paleoclimate patterns.
