Some people here are aware of my blog, some are not. I spend most of my time posting crap there, and shunting some of the illustrations I prepare here and there.

If you care to follow, you will know that I've also been spending some time trying to answer the question about whether dinosaurs had "lips" or "cheeks," a common feature of illustrators and reconstructors for paleontology. Lately, scientifically informed illustrators like Crash McCreedy and Tyler Keillor have been rendering their dinosaurs without "cheeks" and without "lips" in the mammal sense, but rather with "lips" in the lizard and snake sense, structures that have no muscles in them, and were thus immobile.
I've gone into quite a lot of detail about this on my blog, beginning with
"Making Lip of It" qilong.wordpress.com/2011/09/1… , then
"Support for a Lipless, Cheekless Dinosaur World" qilong.wordpress.com/2012/09/0… , then most recently
"Cheeky Commentary on Ornithischians" qilong.wordpress.com/2012/09/1… ,
where I specifically talk about taking the cheeks off ornithischian dinosaurs, which makes them look a little funny. I am not the first person, nor the only one doing this generally, but I'm making a public stink about it because there is real important need in getting our artists informed about the biology. You're all smart enough to do it! Anatomy is an important first step to dealing with dinosaur art, because it is the only way you will know to tell you that that dino "looks real." You need to know WHY. Part of that is knowing also that we don't have all the answers now, but there are several philosophical techniques that help us approach the data, and scientific methods in discriminating "true" from "false" with that information.
