Editing Frontal bone (section)

=== Dinosaurs ===
The frontal bone is one of the principal paired mid-line bones in dinosaur skulls.  This bone is part of the skull roof, which is a set of bones that cover the brain, eyes and nostrils.  The frontal makes contact with several other bones in the skull.  The anterior part of the bone articulates with the nasal bone and the [[Prefrontal bone#In dinosaurs|prefrontal]] bone.  The posterior part of the bone articulates with the postorbital bone and the parietal bone.  This bone defines all of part of the upper margin of the orbit.
