==Classification== Ferganocephale was originally classified in the group Pachycephalosauridae. It would then be one of the oldest known pachycephalosaurids. Robert M. Sullivan however, in 2006 disputed the pachycephalosaur classification, finding "few of the features [...] are characteristic of pachycephalosaur teeth," citing the lack of serrations on the teeth, and concluding the specimens are "too incomplete for identification". He considers the taxon a nomen dubium, and a non-pachycephalosaurid ornithischian. In 2024, a comprehensive analysis of early ornithischian evolution found Ferganocephale to be most similar to Chaoyangsauridae in overall morphology but refrained from referring it to this clade based on its lack of denticles and strength of the cingulum. The authors of this analysis instead considered it an indeterminate member of Saphornithischia.
