7. Linhenykus
You thought the T-rex had it bad with their tiny little arms, well, spare a thought for the Linhenykus. This is the only non-avian dinosaur to sport a single digit on its forelimbs. Whilst in the flying dinosaur, these claws are an elegant addition to their impressive wings, the effect on the Linhenykus is that of the decidedly less sexy clawed nub. If this guy were a human, it's be the kid at school who says things like "My mum says that bullies are just boring people" and walks on the balls of his feet. It's not entirely clear what those little nubs are for, perhaps a handy coat hook or the latest in dinosaur fetish fashion? Who knows, judging from the placid expression on this little guy's face, they obviously don't seem to bother him all that much. Maybe the luxurious deer-like mane of fur serves as some kind of consolation prize.
