Last year I found an iPad app (Ancient Earth: Breakup of Pangea) that allows you to view the earth as a globe you can rotate and zoom in on (like google earth), but instead of just showing the current arrangement of things on the face of the earth today, you can also dial in times back to 200 million years ago. This was made by Christopher Scotese a geologist in Texas based upon his paleomap project (http://www.scotese.com/). You can view data there and purchase some movies.

 

I just found another related website, Global Geology (http://globalgeology.com/) where you can down load (free for some limited amount of time) google world files of the globe at various times in the past.

You have to create an account to do this.

 

These globes can show the following map data (pick one):

Paleogeography    High resolution paleogeography with 3D relief   (Example)
Simplified Paleogeography    Low resolution paleogeography with highstand/lowstand shorelines   (Example)
Basemap    Basemap with coastlines, political boundaries and white background   (Example)
Relief Basemap    Basemap with coastlines, political boundaries and grayscale 3D relief   (Example)
Geology    Geology with 3D relief   (Example)
Paleoclimate Zones    Paleoclimate Zones based on Lithologies (coals, evaporites, etc)   (Example)
Temperature    Mean Annual Surface Temperature with isotherms   (Example)
Rainfall and Runoff    Rainfall (blue squares), Wet Regions (Green), Deserts (Brown)   (Example)
Paleoclimate Reconstruction    Tropical Everwet, Arid, Warm Temperate, Cool Temperate, Polar   (Example)
Winds    Isobars and Winds   (Example)
Salinity    Ocean Salinity   (Example)
Anoxia    Ocean Anoxia   (Example)
Upwelling    Zones of Oceanic Upwelling   (Example)
Tectonics    Plate Tectonics   (Example)

 

 

Here are the available time periods (pick one):

I think these maps are fun and could be useful for non-profit uses like talks and lectures, so I am letting people know about them here.

For example, I have used a movie from the Paleomap site showing paleogeography of the Indian ocean region during the last 50 million years to give a general idea of the world in which Danios evolved. This was in some movie format that I could paste into a power point presentation.

I could only get pdf snapshots from Google Earth by choosing print but then clicking save as a pdf (on my Mac). Other forms of output may exist, but this is my first use of Google Earth. If you want to make a movie through time with the Google Earth flies I think you would need to save a series of images from different time globes and string them together in a movie program (like quick time).
