Eocathayornis was a small, early bird that lived during the Age of Dinosaurs. It could flap its wings powerfully and fly like a modern bird, but it still had teeth and claws on its wings.2

izinto ezimnandi

Iinyani ezimnandi

Eocathayornis had a reduced claw on its third wing finger, but the other two wing claws were still present.2

Its radius bone was about three-fourths as wide as its ulna, which helped make its wing strong for flapping.2

The sternum (breastbone) had a keel and a pair of long, backward-pointing processes, adaptations for flight.2

Eocathayornis was about the same size as Cathayornis, another early bird from the same fossil site.2

It lived around 120 million years ago, during the Early Cretaceous period.1

The only known fossil is a skull and upper body preserved as impressions in rock, split into two slabs.1

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

Ukuhlelwa: Theropoda > Avialae3
Ubudala bamatye: 121 ukuya ku-113 izigidi zeminyaka (Aptian)3

Iirekhodi zeefosili: 1 kwi-Paleobiology Database3
Ukufunyanwa: The fossil was collected in 1994 by Zhou Zhonghe from the Jiufotang Formation in Liaoning, China. Zhou named it Eocathayornis walkeri in 2002, honoring Cyril Alexander Walker for his work on Enantiornithes.1 2
Kusaxoxwa ngayo: Scientists are not sure exactly how Eocathayornis is related to other early birds, but it is thought to be more primitive than Cathayornis.1
