Exercise 3 Aging
examine the skeletal material which is from a female and showsthe symphyseal face of the pubis. Compare it with the Suchey-Brooksage phases provided. What is the approximate age of thisindividual?

Mean Age at Phase Death, Female (n = 273) 1 2 3 4 19.4 years 25.0 years 30.7 years 38.2 years Standard Deviation, 95% Range, Female Female 2.6 4.9 8.1 10.9 15-24 years Mean Age at Death, Male (n=739) 21-53 years 18.5 years Standard Deviation, 95% Range, Male Male 19-40 years 23.4 years 3.6 2.1 26-70 years 35-2 years 28.7 years 6.5 9.4 15-23 years 19-34 years 21-46 years Description Symphyseal face has a bil- lowing surface composed of ridges and furrows which includes the pubic tubercle. The horizontal ridges are well marked. Ventral beveling may be commencing. Although ossific nodules may occur on the upper extremity, a key feature of this phase is the lack of delimitation for either extremity (upper or lower). Symphyseal face may still show ridge development. Lower and upper extrem- ities show early stages of delimitation, with or without ossific nodules. Ventral rampart may begin formation as exten- sion from either or both extremities. Symphyseal face shows lower extremity and ven- tral rampart in process of completion. Fusing ossific nodules may form upper extremity and extend along ventral border. Sym- physeal face may either be smooth or retain distinct ridges. Dorsal plateau is complete. No lipping of symphyseal dorsal mar- gin or bony ligamentous outgrowths. Symphyseal face is generally fine-grained, although remnants of ridge and furrow system may remain. Oval outline 23-57 years usually complete at this stage, though a hiatus may occur in upper aspect of ventral circumference. Pubic tubercle is fully separated from the symphyseal face through

Ventrally, bony ligament- ous outgrowths may occur in inferior portion of pubic bone adjacent to symphyseal face. Slight lipping may appear on dor- sal border. 34-86 years Slight depression of the face relative to a completed rim. Moderate lipping is usually found on the dorsal border with prominent 27-66 years ligamentous outgrowths on the ventral border. Little or no rim erosion, though breakdown possible on superior aspect of ventral border. Symphyseal face shows ongoing depression as rim erodes. Ventral liga- mentous attachments are marked. Pubic tubercle may appear as a separate bony knob. Face may be pitted or porous, giving an appearance of disfigure- ment as the ongoing pro- cess of erratic ossification proceeds. Crenellations may occur, with the shape. of the face often irregular.
