He's clearly a moron. In some of the size comparison drawings I find myself wanting to yell at the silly idiot. This is a much better sort of person/dinosaur comparison. It was drawn by Danielle Default, a scientific illustrator from the Royal Ontario Museum, and features her as the human comparison. She has style!

Mind you, it features Zuul crurivastator, which was a herbivore, so it's less silly to start with. Still cool though.
