Dinosaur Shook Tail Feathers for Mating Show

4th January, 2012

Fused vertebrae at the base of the spine and muscle structures of the tail of some Ovirators has led to the suggestion that some dinosaurs shook their tail feathers purely as a form of display.

Similar structures today are observed only in birds. When found in examples of feathered dinosaurs not capable of flight,  the researchers from the University of Alberta suggest this is evidence they were used to shake tail fan displays.
