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.
The skull's dorsal aspect is characterized by a significant expansion due to the large prefrontal regions, which create a pronounced vertical wall above the nasal aperture. This is followed by a steep decline before the skull rises again through the parietal bones.
