Prettige feite

1

Yuanjiawaornis is known from a nearly complete skeleton without a skull, found in 2005 by a paleontologist near the village of Yuanjiawa.1

2

Most enantiornithine birds were as small as sparrows or starlings, but Yuanjiawaornis was much larger, about the size of Zhouornis.12

3

The fossil of Yuanjiawaornis has no preserved feathers, which is unusual for bird fossils from Liaoning.1

4

Yuanjiawaornis lived during the Early Cretaceous period, about 120 million years ago, in the Jiufotang Formation.13

5

The holotype specimen was probably a young adult, because its wrist bones were not fully fused.2

6

Yuanjiawaornis had a uniquely shaped synsacrum (a fused part of the backbone) that may be special to enantiornithine birds.2

Ontdekking
Yuanjiawaornis was named in 2015 by Hu Dongyu and colleagues based on a skeleton found in 2005 near Yuanjiawa village in Liaoning, China.12
Steeds omstrede
Scientists are not sure exactly how Yuanjiawaornis is related to other enantiornithine birds, because its skull is missing.1
