The base of the skull ( Latin base cranii ) is the lower part of the skull . It is made of units of the frontal bone ( frontal ), the ethmoid bone ( ethmoid ), the sphenoid ( sphenoid ), the temporal bone ( temporal bone ) and the occipital bone ( occipital ). In animal anatomy, the frontal bone and ethmoid bone do not count towards the base of the skull, since they are not considered the lower (basal) parts of the skull.
