Sub-pubic Contour Orientation
For the subpubic contour, the dorsal surface of the pubic bone should be held perpendicular to the scorer. The region immediately below the symphyseal face and the entire inferior pubic ramus should be considered.
Trait Scoring
Character states for the SPC (from left to right: Score 1 to Score 5)
Dorsal surface of pubic bone is showing with the superior pubic ramus aligned horizontally
Right innominate, medial side on left
