Unlike last years Salt Lake Comic Con, there was not much in the way of dinosaurs (or geology really) that I could find. I did see one person dressed up as a female Dr. Grant from Jurassic Park but I never was able to get a picture of her. So, in lieu of that, we have Smaug from The Lord of The Rings. Dragons are based on dinosaurs, so essentially dragons are the descendants of dinosaurs, like birds.
Therefore, dragons can be considered the cousins of birds. And in that case, here you have a dinosaur descendant.
Side Note: I didn't realize this at first but one of the eyes opened and closed. You can see that through the 3 pictures below. Very nice!
