Xiaotingia was a small, feathered dinosaur that lived about 160 million years ago. It looked a lot like Archaeopteryx, the famous 'first bird', and scientists are still arguing about whether it was a bird or a raptor.23

1

Xiaotingia had long, strong arms and hands, which scientists used to think were special bird features, but they are actually found in a bigger group called Paraves.2

2

When Xiaotingia was added to the family tree, it made Archaeopteryx move from being a bird to being a raptor, which surprised many scientists.2

3

Xiaotingia had a large hole in its lower jaw, called a surangular foramen, that was more than 6% of the total jaw length.1

4

Its fourth finger bone (metacarpal IV) was thicker than the second and third, which is unusual.1

5

Xiaotingia shared some features with troodontids, like closely packed teeth in the front of the jaw and long, slender tail bones.1

6

The only known fossil was bought from a fossil dealer, so scientists are not 100% sure exactly which rock layer it came from.1

Mosenyi wa ditshomo

Tshomo: Xiaotingia is a bird because it looks like Archaeopteryx.

Nnete: Scientists disagree. Some think Xiaotingia is a raptor (a deinonychosaur), not a bird, because it shares many features with raptors.2

Xiaotingia was named in 2011 by Xu Xing and colleagues. The only skeleton was bought by the Shandong Tianyu Museum of Nature from a fossil dealer who said it came from Liaoning, China.1
E sa ntse e phehwa kgang
Scientists still debate whether Xiaotingia was a bird or a raptor, and even the exact age of the fossil is uncertain because the dealer could not say which quarry it came from.21
