Neovenator and Miragaia. Anthropomorphized. The stars get frustrated at their own fans a bit for making dinosaur popularity into a "coolness contest", deliberately "hating on" dinosaurs that get more press because they think they're "overrated".
They're animal species. Pop bands get overrated. Species do not. It is not a coolness contest. Because someone is all about chin-strap penguins is no excuse to roll your eyes and pine on the sick society that would ignore the fairy blue penguin.
I do like their expressions though. :)
