This is a digital atlas of plate tectonic, paleogeographic, and paleoclimatic reconstructions designed for use with the GIS software, ArcMap (ESRI). Table 1 lists the various types of maps that comprise the PALEOMAP PaleoAtlas. The maps included in this folio are highlighted in bold text (Table 1).The last map in each folio is a rectilinear graticule that can be overlain on the maps to provide a geographic reference frame. A rectilinear projection was used because it can be easily georeferenced in ArcMap and transformed into a variety of other map projections. The rectilinear map projection can also be directly “wrapped” onto a spherical projection, like the one used by Google Earth. A set of Google Earth paleoglobes has made from the maps in this folio. These Google Earth paleoglobes can be downloaded at: www.globalgeology.com. If the map you need is missing, or if there doesn’t seem to be a map folio for the exact time interval of interest, please contact me (

The PaleoAtlas contains one map for every stage in the Phanerozoic, as well as 6 maps for the late Precambrian. Eventually, Map Folios, like this one, will be published for every time interval in the PALEOMAP PaleoAtlas. The following section is a brief description of the maps that makeup the Map Folio.
