       Shanweiniao is a genus of enantiornithine bird that lived in China during the Early Cretaceous.‭ ‬When the genus was described in‭ ‬2010,‭ ‬Shanweiniao was the only known enantiornithine which had a wing structure that was capable of generating lift.‭ ‬The name Shanweiniao means‭ ‘‬fan tailed bird‭’‬,‭ ‬a reference to the structure of the tail feathers.‭ ‬Until the description of Shanweiniao,‭ ‬such a tail had only been seen in one other Mesozoic bird genus called Yixianornis.‭ ‬Shanweiniao is noted for having a snout longer than most other known enantiornithines,‭ ‬and this was likely a feeding specialisation that allowed enantiornithine to pluck out small animals such as insects.
