Shanweiniao was a tiny, long-beaked bird that lived in ancient China. It had a fan-shaped tail that might have helped it fly, just like modern birds!1

izinto ezimnandi

Iinyani ezimnandi

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

Umfanekiso owenziwe yi-AI: Shanweiniao — Umfanekiso owenziwe yi-AI obonisa indlela Shanweiniao esenokuba wayekhangeleka ngayo, wenziwe yikhompyutha ngokwento eyaziwa zizazinzulu. Kukuqikelela nje: esona silwanyana sinokuba sasikhangeleka ngenye indlela, kwaye akukho mntu waziyo imibala yaso yokwenyani.

ubuzile

Eyona mibuzo ibuzwa kakhulu: Shanweiniao

?What did Shanweiniao eat?

Shanweiniao had a long beak, which suggests it may have eaten insects or small animals, but scientists are not sure exactly what it ate.1

?Was Shanweiniao a dinosaur?

Yes, Shanweiniao was a type of bird that belonged to a group called avialan dinosaurs, so it is considered a dinosaur.1

?How big was Shanweiniao?

Shanweiniao was tiny, about the size of a sparrow, but the exact size is not known from the fossil.1

Inyaniso ngeentsomi

Intsomi: Shanweiniao definitely had a fan-shaped tail like modern birds.

Inyaniso: Scientists are not sure. The tail feathers are poorly preserved, and some think they might have been ornamental streamers instead of a lift-generating fan.2
