In determining biological sex from the skull, which of the following features is MOST characteristic of a male skull?

• A Smooth orbital margins, small mastoid process, rounded chin
• B Prominent supraorbital ridges, large mastoid process, square chin ✓
• C Sharp orbital margins, moderate mastoid process, pointed chin
• D Absent glabella, small frontal sinus, V-shaped palate

Explanation

Male skulls characteristically show prominent supraorbital ridges (frontal bossing), a large and projecting mastoid process, a square/heavy chin, and well-developed nuchal crests. Female skulls have smooth orbital margins, small mastoid processes, pointed chins, and less pronounced muscle markings. While the pelvis is the most reliable bone for sexing, the skull is the next most reliable element.
