Dermal bone that bears part of the supraorbital canal and usually covers a large area of the neurocranium occupying part of the ethmoidal, orbitosphenoid, and otic regions. Commonly, the frontal bone articulates with its antimere medially, with lateral ethmoid, orbitosphenoid and pterosphenoid ventrolaterally, with supraorbital bone(s), autosphenotic and pterotic laterally, and with parietal posteriorly.[TAO].

The frontal bone may be paired or unpaired. The frontal bone of actinopterygians is homologous to the parietal of tetrapods. Actinopterygians do not have a frontal bone. For details, see Schultze (2008) and Wiley (2008).[TAO]
