I came across an interesting and useful web site last night while I was working on my manuscript. So I thought I'd bring it to your attention. Some of you may find it useful as well.
University of California Museum of Paleontology
And yes, there is some evolution on the site. So if you send your kids there, be aware. On the other hand, the "Web Geological Time Machine" could be a useful tool to help a student understand the Darwinian scenario, as well as the big picture for the complexity of life's history on earth (something that, in my opinion, is a real problem for global flood geology).
