That would be pretty interesting thing, though I doubt anything would come into fruitation. A history on the grown-ups would be neat. But I like some things, like Pterano, being sort of mysterious. I mean, we know what he did, and were shown bits of his past, but nothing on a daily level or anything. Personally I'd like a book where they'd list out information about all the legends/myths/etc. the dinosaurs from the LBT series have - I've always been interested in mythology.
EDIT:
Yeah, I've always really liked Petrie's mom, though I don't really know why.
