===Parietal Bone===
===Parietal Bone (os parietale)===
*Paired
*Forms the dorsolateral wall of the cranium
*Occipital bone caudally
*Frontal bone rostrally
===Maxilla===
*Composed of a pareital plane, temporal plane and a nuchal plane (in the ox)

*Interpareital bone between the occipital bone and the pareital bone
**Fuses with age
