Prettige feite

Chaoyangia is known from only one partial skeleton, including vertebrae, ribs, hips, and upper leg bones.1

It had more than eight fused sacral vertebrae (the bones that connect to the hips), which is unusual for early birds.1

Chaoyangia was one of the first fossil birds discovered in the famous Jehol biota of China.1

Its ribs had long, slender, angled uncinate processes, which are bony hooks that help with breathing.1

The upper leg bone (femur) of Chaoyangia had a distinct 'neck' that set it apart from other early birds.1

Vir dino-kenners

Wetenskaplike naam: Chaoyangia
Benoem deur: Hou and Zhang 19932
Groep: Vroeë voëls
Familie / klade: Ornithuromorpha2
Klassifikasie: Theropoda > Avialae2
Ouderdom van die rotse: 121 tot 113 miljoen jaar (Aptian)2
Rotsformasies: Jiufotang2
Lande: China2
Fossielrekords: 1 in The Paleobiology Database2
Ontdekking: Chaoyangia was named by paleontologists Hou Lianhai and Zhang Jiangyong in 1993, based on a single fossil found in the Jiufotang Formation near Chaoyang, China.2 1
Steeds omstrede: Scientists are still debating whether Chaoyangia is the same as another early bird called Songlingornis, because the fossils are so incomplete.1
