Chiappeavis Chiappeavis

Chiappeavis is a genus of enantiornithean bird from Early Cretaceous of northeastern China. The only species is Chiappeavis magnapremaxillo. Chiappeavis is classified within the family Pengornithidae. It is known from a single, almost complete skeleton including feather impressions discovered in the Jiufotang Formation of the Jehol Group. Long feathers formed a fan-shaped tail that was probably employed in flight.

The genus name honors Luis Chiappe for his extensive research on Mesozoic birds. The specific name magnapremaxillo (“large premaxilla”) alludes to the unusually large size of the premaxillary bone, the frontmost bone of the upper jaw.
