Gongbusaurus is a genus of ornithischian, perhaps ornithopod, dinosaur that lived between about 160 and 157 million years ago, in the Late Jurassic period.

Gongbusaurus, by extrapolation from the remains of possible species "G." wucaiwanensis and other basal ornithopods, was a herbivorous bipedal animal around 1.3 to 1.5 meters (4.3 to 4.9 ft) long.

[1] Dong Zhiming, Zhou Shiwu, and Zhang Zicheng, who originally described the type species G. shiyii, thought it was most similar to Fabrosaurus and assigned it to the nebulous Fabrosauridae.

These remains came from the Oxfordian-age Upper Shaximiao Formation in Sichuan, China and were found by a unit of the Chinese aerial survey behind an elementary school in the village of Huangtong, part of the Duxin commune, in Rongxian or Rong County.

As shi yi also can mean "register of lost objects" the specific name is at the same time a pun on the fact that the teeth were later separately found among the assorted bones collected during the dig.
