Tianyuornis had teeth in both its upper and lower jaws, which is unusual for birds and helped scientists confirm that some ancient birds still had teeth.1 2

Its lower jaw (dentary) was straight, while other similar birds had a curved, S-shaped jaw. This unique feature helped scientists identify it as a new species.1 2

Tianyuornis was about the size of a modern phoebe, a small songbird, making it quite tiny compared to many dinosaurs.1

It had long hindlimbs (legs) compared to its forelimbs (wings), which suggests it was a good runner.1 2

The only known fossil is a nearly complete and articulated skeleton of a subadult, meaning it was not fully grown when it died.1 2

Tianyuornis lived in a lake environment, and its fossils were found in lake deposits.1
