Actually, my first thought about this was, how can the public add to it?  For example, I have found fossils in Western New York.  My find is not documented anywhere, and I am not sure if it would be valuable knowledge to know what and where I found it, but being able to share my own finds might help complete the picture.  It would be like crowdsourcing the problem.  If they allowed people to upload info (albeit, unverified), it could be shown as a layer and verified over time maybe?<p>In any case, this is very cool, and as a fossil enthusiast, I am super excited to see it!
