Yuornis is one of the most complete Late Cretaceous enantiornithine birds ever found, with a three-dimensionally preserved skull.1

Unlike most enantiornithines, Yuornis had no teeth. Its skull looked a lot like modern birds because it lost several bones, like the lacrimal and postorbital.1

The name Yuornis comes from 'Yu', the one-character abbreviation for Henan province in China, where it was discovered.1

Yuornis lived about 72 to 66 million years ago, during the very end of the Age of Dinosaurs.3

Its closest relative might be Gobipteryx, another toothless bird from the Late Cretaceous, but scientists are not sure because tooth loss evolved many times.1

Nhunumu: Yuornis was named in 2021 by Xu Li and colleagues. The species name junchangi honors paleontologist Lü Junchang. The fossil was found in the Qiupa Formation of Henan, China.1 2
Wɔda so gye ho akyinnye: Scientists are not sure whether Yuornis belongs to the family Gobipterygidae, because the features linking it to that group are all related to tooth loss, which evolved many times separately.1
