Ubirajara
This Brazilian dinosaur flaunted a mane of stiff feathers and ribbon-like shoulder plumes that would make peacocks jealous. Described in 2020, Ubirajara represents one of the most flamboyantly decorated small theropods yet discovered. About the size of a chicken, this Early Cretaceous showoff used its elaborate display features likely to attract mates. The dinosaur proves prehistoric animals could be as flashy as modern birds.
