== Discovery and naming == thumb|Speculative paleoart|life restoration The fossil material referred to Huashanosaurus was found in outcrops of the Wangmen Formation in the Huqiu Quarry near Dongshi Village in Guangxi Zhuang Autonomous Region of southern China. Fragmentary and disarticulated fossil material was first found in this area in 2002 by Jian Qin, a local teacher, while searching for stones near the river. Subsequent excavations were conducted in 2017 by the Natural History Museum of Guangxi (NHMG) and the Cultural Relics Administration of Ningming County (CRAN), during which fish scales and teeth, plesiosaur teeth, and additional fragmentary dinosaur remains were collected. While the specimens collected in 2002 and 2017 are accessioned as separate specimens in different institutions—the holotype, NHMG 034093, and paratype, CRAN 0001—they likely belong to the same individual based on their similar size and form. The holotype comprises one dorsal vertebral , a partial dorsal , the end of a left and top part of a left , a manual (finger bone), part of the left , the end of a and , and part of a fifth and pedal ungual (foot claw). The paratype includes three anterior (toward the front) and a neural spine, a middle caudal vertebra, and a pedal phalanx.
