Guidraco venator
This snaggle-toothed skull belonged to Guidraco venator, a carnivorous pterosaur that took to the air 120 million years ago with a wingspan up to 3 meters (15 feet). Yes, we know pterosaurs aren't dinosaurs, but we're making an exception for this fearsome flier. Also, its name is a Chinese-Latin mashup that means "ghost dragon hunter."
The tangle of teeth at the end of its beak may have helped it catch fish, researchers reported last year in Naturwissenschaften. Other scientists aren't so sure about that, but one things seems certain: whatever ended up in those teeth met a bad end.
