Yayitya: InyamaIintaka zokuqalaiCretaceous yokuqala

Archaeornithura was a tiny bird that lived about 130 million years ago. It is the oldest known relative of all modern birds. This little bird had feathers and could fly well, just like birds today.2 1

Iinyani ezimnandi

Archaeornithura is the oldest known ornithuromorph, the group that includes all living birds.2 1

It lived 130.7 million years ago, which is about 5 to 6 million years older than any other known ornithuromorph.1

This bird had a well-developed alula, a small feathered finger on the front edge of its wing that helps with maneuverability in flight.2

Archaeornithura had fan-shaped tail feathers and a U-shaped furcula (wishbone), features seen in modern birds.2

Only two fossils of Archaeornithura have been found, both from the Huajiying Formation in China.2 1

Its discovery pushed back the first appearance of ornithuromorph birds by about 6 million years.1

Umfanekiso owenziwe yi-AI: Archaeornithura — Umfanekiso owenziwe yi-AI obonisa indlela Archaeornithura 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: Archaeornithura
Inikwe igama ngu:: Wang et al. 20153
Iqela: Iintaka zokuqala
Usapho / iclade: Hongshanornithidae3
Ukuhlelwa: Theropoda > Avialae3
Ubudala bamatye: 133 ukuya ku-126 izigidi zeminyaka (Hauterivian)3
Izakhiwo zamatye: Huajiying3
Amazwe: iTshayina3
Iirekhodi zeefosili: 1 kwi-Paleobiology Database3
Ukufunyanwa: Archaeornithura was named in 2015 by a team led by Wang Min and Zhou Zhonghe. The fossils were bought from a fossil dealer and came from the Huajiying Formation in Hebei, China.2 1
Kusaxoxwa ngayo: Scientists are still debating exactly how Archaeornithura is related to other early birds and whether it was a wading bird like its relatives.1
