Jian

Igama lithetha: “one-winged bird from Chinese mythology”1

Yayitya: InyamaIiraptaiCretaceous yokuqala

Jian was a small, feathered dinosaur that lived about 120 million years ago. It had long feathers on its arms and legs, like four wings, and probably glided through the air like a flying squirrel. Scientists think it hunted early birds, because its fossils were found in a place full of bird bones.2

izinto ezimnandi

Iinyani ezimnandi

Jian is one of the biggest microraptor dinosaurs ever found. Its upper arm bone is about 10 centimetres (4 inches) long.2

Jian had a very long coracoid bone in its shoulder, longer compared to its arm than in any other microraptor.1

The only fossil of Jian found so far is an arm and shoulder. No other bones have been discovered yet.1

Jian lived alongside hundreds of early birds called Gansus yumenensis. Its fossils were found in the same rock layer as many bird skeletons.1

Scientists think Jian may have been the predator that left behind crushed bird bones at the site, similar to pellets coughed up by modern owls.2

Jian probably could not fly like a bird, but it could glide using its four feathered limbs, much like a flying squirrel.2

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

Kwiingcali zeedayinaso

Igama lenzululwazi: Jian
Inikwe igama ngu:: Zhou et al. 20263
Iqela: Iirapta
Usapho / iclade: Dromaeosauridae3
Ukuhlelwa: Theropoda > Dromaeosauridae3
Ubudala bamatye: 121 ukuya ku-113 izigidi zeminyaka (Aptian)3
Izakhiwo zamatye: Xiagou3
Amazwe: iTshayina3
Iirekhodi zeefosili: 1 kwi-Paleobiology Database3
Ukufunyanwa: Jian was named in 2026 by a team of scientists including Zhou, Lamanna, Poust, Li, You, and O'Connor. The only fossil found is an arm and shoulder from the Xiagou Formation in China.3 1
Kusaxoxwa ngayo: Scientists are not sure if Jian could truly fly or only glide, because only its arm and shoulder bones have been found.2
