Annea was surfing the web last night for various odds & ends for her collection of teaching aids for her upcoming instructorship and found an interesting collection of 20 paleogeographic maps from Precambrian to Future +250 million years; at each map page (upper left ("more information") there is more information about each geological time period. She saved a set to her laptop (which I copied to mine) as visual aids for continental drift and the origins of the continents & seas. Neat stuff! Example here is Late Jurassic.
