Paleomap Project of Christopher R Scotese
Good maps and descriptive material, plus animations. Contains free downloads and information for ordering further resources. Scientifically authoritative. British Stratigraphic nomenclature is used, but beware some american spellings (e.g. paleo, instead of palaeo). "The goal of the Paleomap project is to illustrate 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". "In the Earth History section of this website are full-color paleogeographic maps showing the ancient mountain ranges and shorelines, active plate boundaries, and the extent of paleoclimatic belts".
