Cowboys & Saurians: Ice Age

I am big into odd facts and stories; this did not disappoint.

If only 1% of these stories were true, then the world that we're living in is a lie.Some of them seem so easy to believe that they must most certainly be true;But are the really interesting ones true ?Is there a mysterious valley far up north that allows dinosaurs to thrive ?Perhaps a cave that leads into an interworld, that remains tropical & is full of all sorts of wondrous animals that occasionally venture out into our familiar world ???
