That one would have featured a post-apocalyptic story set in the aftermath of an unspecified anomaly that caused all of Earth's history to come crashing together. The result is that the map is now a patchwork of modern ruins and prehistoric wilderness, and the original story would have featured a father saving his daughter from a tyrannosaur by luring a herd of mammoths to the scene.

I think it would make a good campaign setting.

This is, basically, Sidewise in Time by Murray Leinster, with a healthy dollop of, Xenozoic Tales, by Mark Schultz, for good measure. :)

Not that this is a bad thing, by any stretch.
Who doesn't like, "Cadillacs and Dinosaurs"?
