Yayitya: InyamaIidayinaso ezitya inyamaiCretaceous yokuqala

Zhongornis was a tiny, feathered dinosaur that lived about 125 million years ago in what is now China. It had a beak with no teeth and a short tail, making it look a bit like a bird. It is special because it helps show how some dinosaurs evolved into birds.1 2

izinto ezimnandi

Iinyani ezimnandi

Zhongornis had a beak with no teeth, unlike many other early birds.1

Its tail had only 13 vertebrae, much fewer than the 22 in Archaeopteryx, a more primitive bird-like dinosaur.1

The third finger of Zhongornis had only two bones, which is more like advanced birds than like earlier dinosaurs.1

Zhongornis is the only fossil found that seems to be intermediate between long-tailed birds like Archaeopteryx and short-tailed birds like Confuciusornis.1

The only known specimen was a juvenile, but it had already grown feathers on its hand and tail.1

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

ubuzile

Eyona mibuzo ibuzwa kakhulu: Zhongornis

?How big was Zhongornis?

It was tiny, about 8 centimeters long (roughly 3 inches).1

?Did Zhongornis have feathers?

Yes, it had feathers on its hand and tail, as shown by impressions on the fossil.1

?What did Zhongornis eat?

It was a meat-eating dinosaur, but its beak had no teeth, so it probably ate small prey or insects.1

?Is Zhongornis a bird?

Scientists disagree. Some say it is a primitive bird, while others think it is a close relative of the Scansoriopterygidae, a group of non-bird dinosaurs.1 3

Inyaniso ngeentsomi

Intsomi: Zhongornis was a true bird.

Inyaniso: Zhongornis was a dinosaur, not a bird. It is a primitive member of the group that includes birds, but it is not a bird itself.1

Kwiingcali zeedayinaso

Igama lenzululwazi: Zhongornis
Inikwe igama ngu:: Gao et al. 20084
Iqela: Iidayinaso ezitya inyama
Usapho / iclade: Paraves4
Ukuhlelwa: Theropoda4
Ubudala bamatye: 126 ukuya ku-120 izigidi zeminyaka (Barremian / Aptian)4
Izakhiwo zamatye: Yixian4
Amazwe: iTshayina4
Iirekhodi zeefosili: 1 kwi-Paleobiology Database4
Ukufunyanwa: Zhongornis was named by Gao et al. in 2008. The only specimen was donated to the Dalian Natural History Museum in China by a woman named Ms. Hao, and the species is named after her.1 2
Kusaxoxwa ngayo: Scientists are still debating whether Zhongornis is more closely related to birds with short tails or to those with long tails, because it has features of both.1
