This United States Geological Survey (USGS) publication covers the subject of North American paleogeography: how the continent has changed over geologic time in terms of location, climate, and other geographical factors. Clues for detecting this information include looking at fossils, rocks, and different kinds of maps. The geographic history of North America is traced from the supercontinent Pangea 200 million years ago (Mesozoic Era)through today, with emphasis on the coal, dinosaur, and ice ages.
