Yuornis was a bird that lived alongside the last dinosaurs. It had a toothless beak, just like modern birds, which was very rare for its time.1

izinto ezimnandi

Iinyani ezimnandi

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

Umfanekiso owenziwe yi-AI: Yuornis — Umfanekiso owenziwe yi-AI obonisa indlela Yuornis esenokuba wayekhangeleka ngayo, wenziwe yikhompyutha ngokwento eyaziwa zizazinzulu. Kukuqikelela nje: esona silwanyana sinokuba sasikhangeleka ngenye indlela, kwaye akukho mntu waziyo imibala yaso yokwenyani.

Igama lenzululwazi: Yuornis
Inikwe igama ngu:: Xu et al. 20213
Iqela: Iintaka zokuqala
Usapho / iclade: Enantiornithes3
Ukuhlelwa: Theropoda > Avialae3
Ubudala bamatye: 72 ukuya ku-66 izigidi zeminyaka (Maastrichtian)3
Izakhiwo zamatye: Qiupa3
Amazwe: iTshayina3
Iirekhodi zeefosili: 1 kwi-Paleobiology Database3
Ukufunyanwa: 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
Kusaxoxwa ngayo: 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
