Some 250 million years ago, at the beginning of the Secondary or Mesozoic era - the age of the large saurians - all the continents were grouped into a single supercontinent known as Pangaea. The Changing Face of the Earth shows the nine most important stages in the break-up of this supercontinent. Nine 'milestones' illustrate the paths along which the different continental blocks drifted to arrive at the geological face of the Earth, as we know it today.

Included are 11 maps, based on scientific work, that are accompanied by explanatory notes aimed at the broad public as well as glossary of terms used in the explanatory notes and a CD-ROM of the map images in various formats (bmp, tiff, pict and Powerpoint).
