Datu dibertigarriak

1

Aurornis is the oldest known avialan, the group that includes birds and their closest dinosaur relatives.2

2

The only fossil of Aurornis is a complete skeleton with traces of fluffy, down-like feathers around the neck and chest.1

3

Aurornis lived during the Middle to Late Jurassic period, about 168 to 152 million years ago.3

4

Its name means 'dawn bird' because it lived near the beginning of bird evolution.1

5

Aurornis was about 51 centimeters (20 inches) long, about the size of a modern chicken.1

6

Scientists think Aurornis could not fly using its forelimbs like modern birds, but it may have glided or used its feathers for balance.2

Aurornis lived about 160 million years ago, during the Middle to Late Jurassic Period. Some scientists are not certain of the exact age because the fossil's origin is unclear.45

?Could Aurornis fly?

Probably not like modern birds. Its short forelimbs suggest it could not fly using powered flight, but it may have glided or used its feathers for display or balance.41

?Is Aurornis older than Archaeopteryx?

Aurornis was named in 2013 by Pascal Godefroit and colleagues. The fossil was found in the Tiaojishan Formation of Liaoning, China, and was named after Xu Xing, a famous Chinese paleontologist.31
Oraindik eztabaidagai
Scientists debate whether Aurornis could fly or just glide, because its feathers were simple and not suited for powered flight.2
