| | The Cambrian (Site not responding. Last check: 2007-10-13) |
 | | World Paleogeography: The supercontinent Pannotia had begun to break up as the Iapetus Ocean formed in between Laurentia (North America), Siberia, Baltica (North Europe), and Gondwana (South America, Australia, Africa, India, and Antarctica). |
 | | Throughout the Cambrian, Siberia remained east of Laurentia, while Baltica was moving south of Siberia and southeast of Laurentia. |
 | | North American Paleogeography: Fossil evidence tells us that Laurentia was centered on the Equator and rotated so that in present-day terms, Canada was east, instead of north, of the United States. |
