Sexy Dino Crest Baby

Duckbilled dinosaurs of about 90 million years ago had huge crests with complex nasal passages, and used them to honk sexual and social messages, according to a new study in the journal Paleobiology.

"The crest likely evolved to play a role in behavior of both vocal and visual display -- to call to attract a mate or warn of predators or something like that," said David Evans, a researcher at the University of Toronto.

"We can now discount the idea that the structure evolved to increase the sense of smell."


For all the other people out there who never outgrew their love for dinosaurs, I offer you the previous information.
