What is "gobipteryx"

Gobipteryx (from Gobi [referring to the Gobi Desert where it was first discovered], Greek pteron “wing”) is a genus of prehistoric bird from the Campanian Age of the Late Cretaceous Period. It is not known to have any direct descendants. Like the rest of the enantiornithes clade, Gobipteryx is thought to have gone extinct near the end of the Cretaceous.
