Cathayopterus

Cathayopterus is an extinct genus of ctenochasmatid pterosaur from the Early Cretaceous-age Yixian Formation of Liaoning, China. The name means "China wing", using the word "Cathay" as an old alternative name for China. The type species is C. grabaui, described in 2006 by Wang Xiaolin and Zhou Zhonghe. The species name honors the late American geologist Amadeus W. Grabau, a pioneer in the study of the Jehol Biota. It is a member of the Ctenochasmatidae, a clade of mostly filter feeding pterosaurs from the Jurassic and early Cretaceous.
