A bunch of years ago at an IPMS Nationals there was a seminar on

(shock) "Painting Dinosaurs." I *think* it was at the Atlanta show (FWIW). Anyway, his take was that dinosaurs were big like tanks, so he had a collection of models where he used the camo that was used on armor and used it on his animals. It looked really good. I had taken pics, but for whatever reason I can't find them now.
So while many of us use mammals, birds and fish for inspiration, take a look at camo references for some of your dinos.
