"Yunyangosaurus" is a naked genus of megalosauroid dinosaur that lived in Chongqing, China during the Middle Jurassic.
Description[]
"Yunyangosaurus" was first mentioned in a 2019 SVP abstract book, and was published in 2020. It is known from a disarticulated partial skeleton, consisting of 11 presacral vertebrae, a few cervical and dorsal ribs and chevrons. The animal would have been 4.7 meters (15.4 feet) long. Because it lacks a ZooBank, it is a nomen nudum.
