We describe a new species of Early Cretaceous bird from the Yixian
Formation of Liaoning Province. Xinghaiornis lini gen. et sp. nov. is
relatively large and characterized by a long, toothless rostrum and an
elevated pedal digit I. The design of the skull and feet suggests that
this bird was likely a mud-prober. This discovery provides strong
support indicating that this avian trophic specialization originated
at least 125 million years ago.
