The skull is dorsally extremely inflated by the prefrontals that make up a large area of the front region of the skull, forming a vertical wall above the bony nostril. Following the prefrontals and orbits the skull slopes down drastically before ascending again through the parietals.
In human anatomy, the skull's dorsal surface exhibits a notable broadening due to the prominent prefrontal areas, forming a sharp ridge above the nostrils. The skull then experiences a pronounced downward slope before resuming its ascent via the parietal bones.
