Changmaornis was a small, bird-like dinosaur that lived about 120 million years ago. It had long legs and blunt claws, and it probably spent much of its time walking on the ground or wading in water.1

izinto ezimnandi

Iinyani ezimnandi

Changmaornis is known from just a partial skeleton including foot bones, vertebrae, and part of the hip.1

Its third toe was the longest, which is different from its relative Gansus, where the fourth toe was longest.1

Changmaornis had blunt claws on its feet without strong flexor tubercles, suggesting it did not climb trees much.1

It lived alongside other early birds like Gansus, Yumenornis, and Jiuquanornis in the same ancient lake area.1

Scientists think Changmaornis may have been aquatic, like a modern loon or grebe, because its foot bones look similar.1

The name Changmaornis comes from Changma Town in China, where the fossil was dug up.1

Umfanekiso owenziwe yi-AI: Changmaornis — Umfanekiso owenziwe yi-AI obonisa indlela Changmaornis 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: Changmaornis
Inikwe igama ngu:: Wang et al. 20132
Iqela: Iintaka zokuqala
Usapho / iclade: Ornithuromorpha2
Ukuhlelwa: Theropoda > Avialae2
Ubudala bamatye: 121 ukuya ku-113 izigidi zeminyaka (Aptian)2
Izakhiwo zamatye: Xiagou2
Amazwe: iTshayina2
Iirekhodi zeefosili: 1 kwi-Paleobiology Database2
Ukufunyanwa: Changmaornis was named in 2013 by Wang Y.-M. and colleagues based on a fossil found in the Xiagou Formation of Gansu, China. The species name houi honors Professor Lian-Hai Hou, who named the first Mesozoic bird from China.1
Kusaxoxwa ngayo: Scientists are not sure whether Changmaornis lived mostly on land or in water, because its skeleton is incomplete.1
