| abstract | - In 1996, a humble peasant named Li Yinxian found the fossilzed bones of a dinosaur near the town of Sihetun in China. However, it wasn't until 1999 that the fossils were rediscoverd, examined, and named by paleontologists Xu Xing, Tang Zhilu, and Wang Xiaolin, and later published in an article in the Nature Magazine. The specimen was named Beipiaosaurus inexpectus, or "unexpected Baipiao lizard". At first, base on the peg-like teeth, scientists thought it was a species of prosauropod, like Plateosaurus, but when more specimens of dinosaurs with long necks, big bodies, extending arms with clawed hands, and theropod-like feet were discovered, they realized Beipiaosaurus was part of a genus of dinosaurs now called therizinosaurs. What makes Beipiaosaurus special, though, is scintists now know that, based off its primitive appearance, therizinosaurs actually evolved from coelurosaurs like dromaeosaurids (Raptors) rather than sauropodomorphs or ornithiscians as thought of previously. It also, from very well-preserved specimens, clued us in that therizinosaurs more than likely had feathers overing their whole bodies.

A second specimen was described by Xu et al. in 2009, which preserved a complete skull as well as a significant covering of unique, elongated feathers. The exact classification of therizinosaurs had in the past been hotly debated, since their prosauropod-like teeth and body structure indicate that they were generally herbivorous, unlike typical theropods. Beipiaosaurus, being considered to be a primitive therizinosauroid, has features which suggest that all therizinosauroids, including the more derived Therizinosauridae, to be coelurosaurian theropods, not sauropodomorph or ornithischian relatives as once believed.
