''Dalianraptor'' (meaning "Dalian thief") is a genus of prehistoric bird that lived in China about 120 million years ago, during the early Cretaceous Period. It is very similar to the contemporary avialian ''Jeholornis'', though it has a longer digit I (thumb-equivalent) and shorter forelimbs, which suggests it may have been flightless. Reaching about in length, it was found in Jiufotang Formation rocks in Liaoning Province. More recently, it is being suspected that the specimen is a chimera forged for the fossil trade, namely a ''Jeholornis'' with the arms exchanged by those of a flightless theropod. == References ==
