Xingtianosaurus was a small, feathered dinosaur that lived in what is now China. It had long feathers on its arms and tail, like a bird. Scientists think it used its feathers for display or to help keep warm.2 1

izinto ezimnandi

Iinyani ezimnandi

Xingtianosaurus is known from a nearly complete skeleton, but the skull is missing. That is why it was named after a headless god.1 2

Its arms were longer than its shoulder blades, which is unusual for early oviraptorosaurs.2

Xingtianosaurus had a very short first finger bone, less than 40% the length of the second finger bone.2

It lived about 125 million years ago, during the Early Cretaceous period.3

Fossilized feather imprints were found near its forearm and hand bones, showing it had long wing-like feathers.2

Xingtianosaurus belongs to a group called Caudipteridae, which includes some of the earliest feathered dinosaurs.2 1

Umfanekiso owenziwe yi-AI: Xingtianosaurus — Umfanekiso owenziwe yi-AI obonisa indlela Xingtianosaurus 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: Xingtianosaurus
Inikwe igama ngu:: Qiu et al. 20193
Iqela: Iidayinaso ezingaqhelekanga ezineentsiba
Usapho / iclade: Caudipterygidae3
Ukuhlelwa: Theropoda > Oviraptorosauria3
Ubudala bamatye: 126 ukuya ku-120 izigidi zeminyaka (Barremian / Aptian)3
Izakhiwo zamatye: Yixian3
Amazwe: iTshayina3
Iirekhodi zeefosili: 1 kwi-Paleobiology Database3
Ukufunyanwa: Xingtianosaurus was named in 2019 by Rui Qiu and colleagues. The only skeleton was found in the Yixian Formation of Liaoning, China.2 1
Kusaxoxwa ngayo: Scientists are not sure exactly how Xingtianosaurus is related to other oviraptorosaurs, because its skull is missing.2
