Best evidence yet that dinosaurs used feathers for courtship
Date:1/3/2013

vertebrae to propel oviraptor's tail feathers vigorously from side to side and up and down.

Oviraptors were two-legged dinosaurs that had already gone through major diversifications from the iconic, meat eating dinosaur family. Oviraptors were plant eaters that roamed parts of China, Mongolia, and Alberta during the Cretaceous period, the final age of the dinosaur.

"By this time a variety of dinosaurs used feathers for flight and insulation from the cold, "said Persons. "This shows that by the Late Cretaceous dinosaurs were doing everything with feathers that modern birds do now," said Persons.

In addition to feathered-tail waving, oviraptors also had prominent bone crests on their head, which Persons says the dinosaur also may have used in mating displays.

"Between the crested head and feathered-tail shaking, oviraptors had a propensity for visual exhibitionism," said Persons.
