Ferganocephale was possibly an early pachycephalosaurian dinosaur. It was from the Middle Jurassic of Kyrgyzstan. The type species, Ferganocephale adenticulatum, was first described by Averianov, Martin, and Bakirov in 2005, and is based solely on teeth. Sullivan, 2006, disputes the pachycephalosaur classification, fininding "few of the features [...] are characteristic of pachycephalosaur teeth," citing lack of serrations on the teeth, and concludes the specimens are "too incomplete for identification" [1].
