Yunyangosaurus (meaning "Yunyang County lizard") is a genus of possible megalosauroid dinosaur from the Xintiangou Formation in Chongqing, China. The type and only species is Yunyangosaurus puanensis.[1] The name was first published in the 2019 SVP abstract book by Dai (2019) before it was formally described by Dai et al. (2020).[2]
The holotype specimen consists of a disarticulated partial skeleton consisting of "eleven presacral vertebrae, several cervical and dorsal ribs and chevrons." Judging from the remains, the animal would have been 4.7 meters (15.4 feet) long.
