Composed of three sets of cartilage bones and two sets of dermal bones. Cartilage bone components include paired pterosphenoids (alisphenoids in earlier literature), the median basiphenoid, and sclerotic cartilages. The two set of dermal bones are the paired frontals and the circumorbitals. Advance teleosts usually have infraorbital, lachrymal/preorbital, jugal/true suborbital, and the dermosphenotic bones/postorbitals. Many primitive teleosts also have an antorbital and a supraorbital
