Tienshanosaurus was discovered by Yuan Fu. The holotype specimens of Monolophosaurus and Sinraptor were discovered in the vicinity by researchers from the China-Canada Dinosaur Project. Fossils of Mamenchisaurus have also been found at the site. Before its name was finalized, Monolophosaurus was known alternatively as "Jiangjunmiaosaurus" and "Monolophosaurus jiangjunmiaoi" in reference to the ruins where it was found. Jiangjunosaurus was named in 2007 in reference to Jiangjunmiao. Various institutions have participated in digs at Jiangjunmiao including George Washington University, the Guangdong Museum, the Institute of Vertebrate Paleontology and Paleoanthropology, the National Autonomous University of Mexico, Northern Arizona University, and the Royal Tyrrell Museum of Palaeontology.
