This is a cool drawing that Jim gave me some years back. It's interesting to see how much his depictions of dinosaurs have changed over the years. As readers of Jim's "Paleo" series of comics can attest, he draws them in a far more realistic manner now.
I'm not sure, but I think this drawing may be associated with the short-lived "Dino Island" comic Jim did which was published by Mirage back in the 1990's. -- PL
