Longipteryx chaoyangensis Longipteryx

Longipteryx is a genus of prehistoric bird which lived during the Early Cretaceous (Aptian stage, 120.3 million years ago). It contains a single species, Longipteryx chaoyangensis. Its remains have been recovered from the Jiufotang Formation at Chaoyang in Liaoning Province, China. Apart from the holotype IVPP V 12325 - a fine and nearly complete skeleton — another entire skeleton (IPPV V 12552), some isolated bones (a humerus and furcula, specimens IPPV V 12553, and an ulna, IPPV V 12554) and many other specimens are known to date.

The name Longipteryx means “one with long feathers”, from Latin longus, “long” + Ancient Greek pteryx (πτέρυξ), “wing”, “feather” or “pinion”. The specific name chaoyangensis is from the Latin for “from Chaoyang”.
