If you have not done so, make certain you look at previous work (now way out of 
date!) related to this by Haubold (1990):
HAUBOLD, H. 1990. Dinosaurs and fluctuating sea levels during the Mesozoic. 
Historical Biology 4:75-106.

As for electronic databases: the Paleobiology Database 
(http://paleodb.org/cgi-bin/bridge.pl) includes in its records the Weishampel
et al. chapter on distributions from Dinosauria 2nd Edition. You can check with 
Matt Carrano at the Smithsonian for more details: he
is responsible for getting that data into the files.

Good luck, and I will be very interested in your results.
