       Ambopteryx is a genus of scansoriopterygid dinosaur that lived in Asia during the late Jurassic.‭ ‬The name Ambopteryx means‭ '‬both wing‭’ ‬and this is a reference to the observations that fossil impressions with the holotype skeleton show that Ambopteryx‭ ‬was feathered,‭ ‬but then had bat-like membranous wings which were not feathered as well.‭ ‬This is the second time that such a‭ '‬wing‭’ ‬structure has been seen in such dinosaurs,‭ ‬the genus Yi has also been reconstructed with bat-like membranes on the arms.‭
       Ambopteryx was a very small dinosaur,‭ ‬the holotype individual measuring thirty-two centimetres from snout to tip pygostyle,‭ ‬though long tail feathers also grew from the tail,‭ ‬giving the impression that Ambopteryx was longer than it actually was.‭ ‬Ambopteryx also preserves evidence of gastroliths and small bones within what would have been the stomach/gut area of‭ ‬the living animal.‭ ‬These show that Ambopteryx may have been omnivorous,‭ ‬an important discovery as before this scansoriopterygid dinosaurs were thought to be more exclusively omnivorous.
