more curved downwards nasal, much more robust and proportionally higher quadrate and the strong ridge extends obliquely along the lateral side of the exoccipital condyloid in Kundurosaurus. Additionally, the frontals of Kerberosaurus are particularly narrow and do not participate in the orbital margin, the rostral margin of the parietal is depressed around the contact area with the frontals, and Kerberosaurus has hook-like palatine process. On the other hand, Xing et al. (2014) considered Kundurosaurus nagornyi to be a junior synonym of Kerberosaurus manakini on the basis of their co-occurrence within the same formation and presence of shared characters in their skeletons. The cladogram below follows Godefroit et al. (2012) analysis.
