Cassowaries and Corythoraptors
In 2017, paleontologists discovered an unusual dinosaur in southern China called Corythoraptor jacobsi. Dating back to the Late Cretaceous, the bipedal oviratporid was remarkably similar to modern cassowaries, a flightless bird native to Queensland, Australia.
In addition to sharing a similar body shape, both animals feature elaborate crests, called a casque, on the top of their heads, which likely serve as advertisement for prospective mates.
