Gracilornis was a tiny, early bird that lived in China during the Age of Dinosaurs. It had a very slender skeleton and could fly, but it was not a dinosaur itself. It belonged to a group of ancient birds called enantiornithines.1 2

izinto ezimnandi

Iinyani ezimnandi

Gracilornis had a very small sternum, or breastbone, compared to its body length. The sternum was only about 11% of the trunk length.3

This bird lived around 110 million years ago, during the Early Cretaceous period.1

The name Gracilornis comes from Latin and Greek words meaning 'slender bird', because its skeleton was very thin and light.1

Gracilornis is known from a nearly complete skull and skeleton, which helps scientists understand what it looked like.1

It belonged to a group called Enantiornithes, which were the most common birds during the Cretaceous period.1

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

Ukufunyanwa: Gracilornis was named by Li Li and Hou Shilin in 2011. They found the fossil in the Jiufotang Formation in Chaoyang, Liaoning, China.1
Kusaxoxwa ngayo: Scientists are not sure exactly how Gracilornis flew, because its small sternum might mean it had weak flight muscles.3
