Within the skeletal system there are three major sets of bones involved in the majority of shifts in relative timing: (1) the membrane bones of the face, specifically, the premaxilla, maxilla, and dentary; (2) other, primarily membranous, bones of the calvaria; and (3) the exoccipital. Other events in the facial region involved in the shifts in timing that differentiate taxa include the appearance of tooth buds, the differentiation of ear ossicles, the closure of the secondary palate, the differentiation of basicranial cartilage and several aspects of muscle development.
