What led you into the fossil hobby? Jurassic Park, this forum, collecting a large number of "dinosaur eggs" and "baby t rex skulls", etc.? For me, it was a book by Peter Larson called "Bones Rock." It was very basic, but introduced scientific thinking to me at a young age, and was well written for small children (as well as giving some basic information on collecting fossils.) Even before that, when I was a wee 5 and 6 year old, I watched the entire BBC "walking with" series. It's still one of my favorites today, even if some of the information is a bit outdated.
