A well-developed sagittal keel is typical among East Asian H. erectus and generally presents as a pronounced bulge that extends the length of the frontal and most of the parietal bone, with parasagittal depressions and a bregmatic eminence. These features are variably expressed in the later MP group.The presence of this ridge of bone indicates that there are exceptionally strong jaw muscles. The sagittal crest serves primarily for attachment of the temporalis muscle, which is one of the main chewing muscles. It is absent or greatly reduced in most Hominins (with the notable exception of the Paranthropus genus).posterior projection from keel gives a smooth transition from heel-strike. sagittal split allows for inversion and eversion. non-articulating. have short or long keels. shorter keels are not as responsive and are indicated for moderate-activity patients.
