I did not find the specific kind of data that I needed, but there were some interesting and useful suggestions. Below is a summary of the responses to my Ecolog post.
---- It might not be exactly what you're looking for, but I heartily suggest investigating the very well done paleogeographical materials that Prof. Ron Blakely (Univ. AZ) has put together; which includes plug-ins for NASA World Wind http://jan.ucc.nau.edu/~rcb7/ http://jan.ucc.nau.edu/~rcb7/regionaltext.html http://jan.ucc.nau.edu/~rcb7/nam.html http://worldwindcentral.com/wiki/Add-on:Paleomaps http://forum.worldwindcentral.com/showthread.php?t=6495 "The globes presented in this series show how Earth may have appeared over the last 600 million years (Ma). The global views were prepared from rectangular projections drawn at a resolution of 3000x1500 pixels for each of the 26 time slices (small files of the rectangular maps are also included). Topography was "cloned" from digital elevation maps of modern Earth from the USGS. Colors were adjusted to portray climate and vegetation for the given time and location. The modern Earth was also drawn in this manner using a color pallet derived from satellite images created by ARC Science of Loveland, Colorado." Includes Precambrian to the present Also see: http://www.google.com/Top/Science/Earth_Sciences/Paleogeography_and_Paleoclimatology/ visually stunning and very informative.

It's an Atlas of the world for various stages by the LGM, with an accompanying literature review: http://www.esd.ornl.gov/projects/qen/nerc.html It's a little out of date (I stopped updating it a few years ago) but not much has substantially changed in the past several years in terms of our view of what the late Quaternary looked like.
