In 2001, Matthew K. Vickaryous, Anthony P. Russell, Philip John Currie and Zhao Xijin named and described the type species Gobisaurus domoculus.

[3] In 2014, Victoria Arbour concluded that Zhongyuansaurus, the type specimen of which, HGM 41HIII-0002, includes extensive postcranial remains, was a possible junior synonym of Gobisaurus.

[2] Gobisaurus domoculus shares many cranial similarities with Shamosaurus scutatus, including a rounded squamosal, short squamosal horns, low supraorbital bosses, large elliptical orbital fenestrae and external nares (oval eye sockets and nostrils), the cross-section of the eye sockets being about a fifth of skull length, a deltoid dorsal profile with a narrow rostrum (a narrow, kite-shaped, snout in top view), quadratojugal protuberances (cheek horns), and caudolaterally directed paroccipital processes (extensions of the rear skull pointing to behind and sideways).

[3] Vickaryous et al., 2004 found that a clade formed by Shamosaurus and Gobisaurus is "nested deep within the ankylosaurid lineage as the first successive outgroup to (the subfamily) Ankylosaurinae".

Saichania Zaraapelta Tarchia Tsagantegia Talarurus Nodocephalosaurus Ziapelta Euoplocephalus Ankylosaurus Anodontosaurus Scolosaurus Zuul Dyoplosaurus In phylogenetic analyses by Xing et al. (2024), Gobisaurus is recovered as a member of Shamosaurinae or as an ankylosaurid less derived than Shamosaurus.
