Yanornis had a long skull with about 10 teeth in the upper jaw and 20 teeth in the lower jaw.1

Its wishbone (furcula) was U-shaped, which helped it fly and walk well.1

Yanornis spent most of its time on the ground because its feet were not good at grasping branches.1

Some scientists think Yanornis might have eaten seeds sometimes, but others disagree.1

The front half of a Yanornis fossil was once glued to the tail of a Microraptor to make a fake fossil called 'Archaeoraptor'.1
