Differences Between Skeletons

In a female skull, the mastoid process is smaller and projects less downward than in a male skull. The zygomatic does not extend past the external auditory meatus. The female skull also has a vertical and rounded frontal bone, which makes for a rounder forehead. The parietal bossing, which is usually found in Caucasoid skeletons, is present in both male and female skulls. It can be seen from the posterior view, just on the superior-lateral edges of the skull.
In a male skull, there is a more robust occipital proturbrance, which is sharper than a female's. The zygomatic process extends past the external auditory meatus, unlike a female's. There is also a larger, more downward protruding mastoid process. On the superior-lateral region of the skull, there are larger, more distinct temporal lines. Where the eyebrows are, there are pronounced superciliary arches. The overall size of the male skull is larger than a female's.

In Caucasoid skulls, there is a more protruding chin form, a high and peaked nasal cross section, a small degree of facial prognathism, a rounded and elongated oval sagittal outline, and a narrowly pointed mastoid process.
In Black American skulls, there is a low and broad nasal cross section. an oblique mastoid process, an elongated and flatter oval sagittal outline, and a more angled facial prognanthism.
In an Asian skull, there is a less prominent chin form and nasal cross section, a less angled facial prognanthism, a more prominent temporal bone, and the overall size of the skull is smaller than the other two.

In a female pelvis, the hip bones are broader and the pubic angle is typically wider; these differences are practical for child-bearing. The overall size of the female pelvis is larger than that of a male pelvis, mostly because of the preparation for child birth.
