complete and articulated skeleton in full plumage, has been recovered from the lacustrine�…

A new genus and species of a basal ornithurine bird is reported from the Lower Cretaceous
Jiufotang Formation of Jianchang, Liaoning, China. It is represented by a nearly complete�…

We report here one of the earliest known beaked ornithurine birds from the Lower
