Scientists have uncovered a previously unknown pterosaur with an enormous sail-shaped crest on its head. Beyond Caiuajara dobruskii's unusual looks, the discovery is also notable because bones from at least 47 of the creatures were found in a small area. “It's kind of like they stumbled on a hidden Caiuajara city,” reporter Deborah Netburn writes.
