A '''dermal bone''', the pattern and form of bones derived from [[intramembranous ossification]], define essential components of the [[vertebrate]] skeleton including the skull, jaws, gills, fins and exoskeleton.
The function of dermal bone is conserved throughout vertebrates, varying in shape and numbers of bones in the [[skull roof]] and postcranial structures. In [[bony fish]], dermal bone is found throughout the body in the fin rays and scales. However, these traits have been lost in higher vertebrates.
