Oviraptors
Did dinosaurs shake their tail feathers to woo a mate? You bet your booty they did, according to a study published in January in Acta Palaeontologica Polonica. The researchers reached that conclusion after studying fossils of oviraptors, small flightless dinosaurs, as well as modern birds and reptiles. The strong, flexible tail of the oviraptor was adorned with multicolored feathers -- perfect for showing off. “You have, I think, a tail that is specifically adapted to flaunt its feathers,” study author Scott Persons told Wired.
