OverviewPlease note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Tianyulong is a genus of heterodontosaurid ornithischian dinosaur. The only species is T. confuciusi, whose remains were discovered in Jianchang County, Western Liaoning Province, China. Its fossilized remains were recovered from the Tiaojishan Formation, dating from the late Jurassic period about 155 million years ago. It is notable for the row of long, filamentous integumentary structures apparent on the back, tail and neck of the specimen. The similarity of these structures with those found on some theropods suggests their homology with feathers and raises the possibility that the earliest dinosaurs and their ancestors were covered with homologous dermal filamentous structures that can be considered primitive feathers ( proto-feathers ).
