homology notes

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]
