Shanweiniao is the only enantiornithine bird known with a tail that could generate lift, like the tails of modern birds.1
Its name means 'fan-tailed bird' in Chinese, because of its special tail feathers.1
Scientists are not sure if its tail really was a fan. Some think the feathers might have been ornamental, like streamers.2
Shanweiniao had a very strong pygostyle, the bone that supports the tail feathers, even stronger than in other enantiornithines.2
It lived about 122 million years ago, during the Early Cretaceous period.1
Only one fossil of Shanweiniao has been found, and it is kept at the Dalian Natural History Museum in China.1
