Two of the features that have been used to diagnose Nedoceratops - the position of the squamosal, and the upright brow horns- are seen on one side of the skull, but not the other. This, along with the fact that the entire skull can be seen to be twisted when seen head-on, have been used to argue that these features result from post-mortem distortion of the fossil, rather than reflecting the anatomy of the animal during life. Furthermore, the presence of numerous holes in the frill suggests pathology due to injury or illness, the supposedly unique 'parietal fenestrae' may therefore be the result of an injury. Tanke & Farke (2007) noted that the supposed parietal fenestra had an irregular shape with swollen margins and an irregularly vascularized texture. This is similar to a parietal hole, also interpreted as the result of an injury by Marshall & Barreto (2001), in a specimen of
