noun
: the arch of bone that extends along the front or side of the skull beneath the orbit, is formed in most mammals by the union of the zygomatic bone with the maxillary bone in front and the zygomatic process of the temporal bone behind, and in lower vertebrates may be modified by the addition of other bones or may be duplicated (as in some reptiles) — compare diapsida |
