The goal of the Earth History segment of the Paleomap Project is to illustrate global plate tectonic development, as well as the changing configuration of landmasses and seas during the past 1100 million years. An array of colorful paleogeographic maps for geologically significant periods of earth's history is provided. Each paleogeographic map displays the reconstructed positions of modern continental coastlines, shelf margins, major tectonic boundaries, active plate boundaries and seafloor spreading isochrones. The maps also include a short discussion indicating important geologic features and events for each period.
