Feilongus (lat.) Is a genus of pterosaurs from the subfamily Moganopterinae of the ctenochasmatid family [1] , who lived during the Barremian – Aptian centuries ( 129.4–113.0 million years ago) [2] . Fossil remains are found in the Lower Cretaceous sediments of the Formations in Beipiao and ( Liaoning , China ).

The name of the family was given in 2005 by Wang Xiaolin and his colleagues. The typical and only species is Feilongus youngi . The name comes from the Chinese feilong - "flying dragon." The species name was given in honor of the Chinese paleontologist Yang Zhongjiang (1897-1979).
The genus Feilongus is based on the IVPP V-12539 holotype - a skull with an articulated lower jaw belonging to a teenage individual, together with a separated skull box on the same fossilized specimen. The remains are badly damaged. It should be noted that there are two bone ridges on the skull: one long and low in the middle of the muzzle, the other protrudes back from the occipital part of the skull. The upper jaw was 10%, or 27 millimeters, longer than the lower. The surviving part of the second ridge was short, with a rounded front edge and, possibly, had an extension of the soft tissues now lost. The only known skull is extremely elongated, with a slightly curved top, has a length of 390-400 millimeters. Wang estimated a wingspan of 2.4 meters, which is quite a lot for the basal group of pterodactyls . The jaws contained 76 long, bent needle teeth, 18 in the upper jaw, 19 in the lower, clamped at the ends of the beak, in the far third [3] .
The cladistic analysis made by the authors of the description showed Feilongus as a sister taxon of the clade , to which cycloramphus (gallodactyl) belonged, and carried them to the family Gallodactylidae (according to Kellner), the clade Ctenochasmatoidea within the superfamily of Archaeopterodactyloidea Kner , containing, according to the words, pterodactyls [3] . Ctenochasmatoids are known for their thin, small teeth, with which they pulled food out of the water, like modern flamingos [4] . However, an analysis conducted in 2006 by Lu Junchang revealed that Feilongus belongs to the Ornithocheiroidea group, closer to the Anhangueridae family [5] . A subsequent publication by the same author and colleagues ranked Feilongus and Boreopterus as a new family of Boreopteridae [6] . In 2014, studies performed by Andres, Clark and Xu Sin confirmed the initial version of Feilongus belonging to the clade Ctenochasmatoidea, but transferred the genus to another family - ctenochasmatids , to the oligotypic subfamily Moganopterinae , which also contains the genus Moganopterus [1] :
