The jaw joint of all jawed vertebrates, except for mammals, involves the quadrate and articular bones, or the posterior ends of the palatoquadrate and mandibular cartilages; A correlate of the conversion of the articular and quadrate bones to the malleus and incus is that all adult mammals have a jaw joint that lies between the dentary of the lower jaw and the squamosal bone of the skull roof.[well established][VHOG]
Inclusion of the FMA class 'lower jaw' is debatable - this mostly corresponds to the lower jaw skeleton (with 'maxillary part of mouth' corresponding to the upper jaw region); however, the FMA class also includes gingiva. See also: https://github.com/obophenotype/mouse-anatomy-ontology/issues/102
