Tianyulong (Chinese: 天宇龍; Pinyin: tiānyǔlóng; named for the Shandong Tianyu Museum of Nature where the holotype fossil is housed) is an extinct genus of...

the fragmentary remains of Lycorhinus may indicate a larger individual. Tianyulong from China appears to preserve filamentous integument which has been interpreted...

possibly from even more distantly related species such as the ornithischian Tianyulong confuciusi and the flying pterosaurs. Thus it appears as if some form...

found preserved with long filaments on the tail, similar to those of Tianyulong. Psittacosaurus probably had complex behaviours, based on the proportions...

smallest known dinosaurs, outside of birds. Known material of Echinodon and Tianyulong, related heterodontosaurids, comes from similar-sized individuals, but...

feather-like structures are also known in some ornithischian dinosaurs (like Tianyulong and Kulindadromeus), and in pterosaurs. Though it is unknown whether these...

there is much debate over whether these filaments found in specimens of Tianyulong, Psittacosaurus, and Kulindadromeus may have been primitive feathers....

structures present in ornithischian dinosaurs, such as Psittacosaurus and Tianyulong, to feathers in theropod dinosaurs and their descendants, birds. Two clades...

Dendrorhynchoides mutoudengensis, and Qinglongopterus guoi, dinosaurs like Tianyulong confuciusi, basal birds like Anchiornis huxleyi, Caihong juji, and Eosinopteryx...

both in coelurosaurs, such as Dilong, and in some ornithischians, like Tianyulong and Psittacosaurus. If the ornithischian quills are homologous with bird...
