[3] Wuerhosaurus homheni is the type species, described by Dong Zhiming in 1973 from the Tugulu Group in Xinjiang, western China.

[3] Its dorsal plates were at first thought to have been much rounder or flatter than other stegosaurids,[7] but Maidment established this was an illusion caused by breakage: their actual form is unknown.

W. homheni had a pelvis of which the front of the ilia strongly flared outwards indicating a very broad belly.

Wuerhosaurus was recovered in a different position by Escaso et al. (2007[9]), still related to Hesperosaurus, but basal to a clade of Lexovisaurus and Stegosaurus.

Maidment et al. (2008[10]) recovered a different placement with Wuerhosaurus as being in a clade of taxa in derived Stegosaurinae, most closely related to Hesperosaurus and then Stegosaurus.

[10] More recently, Maidment (2017[11]) elaborated upon her earlier analyses, and instead resolved Wuerhosaurus as closest to Stegosaurus, with Hesperosaurus being more closely related to Miragaia.

[11] Huayangosaurus taibaii Chungkingosaurus jiangbeiensis Tuojiangosaurus multispinus Paranthodon africanus Jiangjunosaurus junggarensis Gigantspinosaurus sichuanensis Kentrosaurus aethiopicus Dacentrurus armatus Loricatosaurus priscus Hesperosaurus mjosi Miragaia longicollum Stegosaurus stenops Wuerhosaurus homheni Maidment and colleagues proposed in 2008 that Wuerhosaurus was a junior synonym of Stegosaurus, with W. homheni being renamed Stegosaurus homheni, and W. ordosensis being a dubious taxon.

He discussed how the diagnoses and features used by Maidment et al. were inconsistent and generalized, with Wuerhosaurus homheni bearing numerous differences.

[13] Stegosaur footprints from the Tugulu Group in Xinjiang Province, China, have been attributed as registered by W. homheni individuals.
