The alisphenoid in mammals is part cartilage bone, part membrane bone[PMC1231738] In many mammals, e.g. the dog, the greater wing of the sphenoid bone stays through life a separate bone called the alisphenoid[WP].
The mammalian alisphenoid forms the greater wing of the sphenoid bone, which contributes a small part of the skull vault just caudal to the orbit, and also underlies the basal part of the frontal and parietal bones in the fetus (Iseki et al. 1997)
