酷東西

趣味知識

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

發現: 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
仍有爭議: Scientists are still debating whether Chaoyangia is the same as another early bird called Songlingornis, because the fossils are so incomplete.1
