Wuerhosaurus is the name of a species belonging to stegosaurid dinosaurs that lived in during the Early Cretaceous Period of China and Mongolia. This makes it one of the few genera of stegosaurians believed to exist as the majority of them existed in the latter half of the Jurassic.

Wuerhosaurus Homheni is the most well-known species, as described by Dong Zhiming in 1973 from the Tugulu Group in Xinjiang, western China. The name of the species is derived from Wuerho, the town of Wuerho. Three distinct localities within the Wuerho Valley were discovered to include remains of the new Stegosaur species: 64043-5; 6443 and 64045. The remains comprised of the holotype Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) V.4006, an unmarked skull-less fragmentary skeleton as well as Paratype IVPP V.4007. The holotype specimen includes a largely full sacrum and pelvis, minus an ischium. It also includes the caudal’s first vertebrae as well as two dorsal vertebrae an scapulocoracoid and humerus, as well the phalanx, and two plates that are dermal. 3 posterior cervical vertebrae of the tail as well as a portion of the ulna of another individual make up the paratype and Dong identified a part of an ischium from a different location to Wuerhosaurus.

A smaller stegosaur found in the Ejinhoro Formation in the Ordos Basin of Inner Mongolia was found in 1988. In the time that this sample (IVPP V.6877) is first described in the work of Dong the year 1993 it was referred to as W. ordosensis, as it was of a similar age and had the same anatomy. The holotype contains a nearly complete torso comprised of 3 cervical vertebrae all 11 dorsal vertebrae (with attached ribs) as well as a complete sacrum that has an ilium right, and the first five vertebrae of the caudal which are all of which are articulated. Another dorsal vertebra, as well as dermal plate were identified as the taxon at the time it was called. In 2014, Ulansky introduced a brand novel species in Wuerhosaurus, “W. mongoliensis” for pelvic and vertebrae material, however the name is a bogus nomen nudum. It was officially described as Mongolostegus in the year 2018.
