Heyuan dinosaur (scientific name) is a kind of dinosaur, belonging to Anantosauridae, which lived in the Heyuan area of China in the late Cretaceous. Its arms and fingers are short, and its thumb has degenerated.
The discovery process "Yellow River Source Dragon" was unearthed in 1999. After years of restoration and research, Dr. Lu from the Institute of Geology, Chinese Academy of Geological Sciences officially named nine dinosaur fossils unearthed in Heyuan as "Yellow River Source Dragon" in "A New Stolen Egg Dragon in Southern China in the Late Cretaceous" published in the fourth issue of the famous American magazine "Vertebrate Zoology" (JVP) in February 2002. This paper proves that "Yellow River Source Dragon" is a new genus and new species of Ovipodaceae. The name Heyuan refers to the origin of fossils. This name is given to Huang Dong, director of Heyuan Museum, who has made great contributions to the excavation and protection of these fossils. The fossil "Yellow River Source Dragon" not only provides the first conclusive evidence of the discovery of the egg-stealing dragon outside the Gobi desert in Mongolia, but also provides a specimen for the bird status of the egg-stealing dragon. In the future, all the newly discovered and studied dinosaurs in the world will be named "Yellow River Source Dragon", which indicates that the research results of Heyuan dinosaurs have gone to the world.
