Xiangornis was an ancient bird that lived about 120 million years ago. It had a mix of features from two big groups of early birds, making it a mysterious and special creature. Its wing bones were already fused together like in modern birds, which helped it fly strongly.1 2

Xiangornis belongs to a group called Enantiornithes, which were the most common birds during the Cretaceous period.3 1

Its wing bones (carpometacarpus) were completely fused together, both near the body and far from it, just like in modern birds.1 2

Xiangornis had a large extensor process on its wing, a bony bump that helped attach muscles and ligaments for strong flight.1 2

This bird shows that some features thought to belong only to modern birds actually evolved earlier and separately in enantiornithines.1 2

The name Xiangornis comes from Mandarin words meaning 'free flight' and the Greek word for bird.1 2

Xiangornis lived during the Aptian age, about 121 to 113 million years ago, in what is now Liaoning, China.3

Gisees: Xiangornis was named by Hu and colleagues in 2012 based on a partial skeleton found in the Jiufotang Formation of Liaoning, China. The fossil includes wing and shoulder bones.3 1
Ñu ngi koy werante ba tey: Scientists are still debating whether Xiangornis is truly an enantiornithine or if it blurs the line between enantiornithines and ornithuromorphs (the group that includes modern birds).1 2
