When the skull is turned even slightly away from a direct lateral view we can see that the frill forms a rather large U bend in the center of the dorsal end of the frill. The small hornlets, or epiparietal horns, are turned down and forward (decurved/rostral and anterior facing). Also we can see that skin stretched tightly over the entire frill would accent the fenestrations by being "sucked" into the bony windows slightly but enough that we would be able to notice them. This theme occurs constantly in the recreation of ceratopsians and, given the idea that the fenestrations existed to lighten the bone rather than house important organs, it makes a great deal of sense that skin and other tissues above those holes would not disguise their existence by puffing outward or anything of the like.
