Age changes in the pubic bone

Abstract

Age 22-24. Pliase 2 :-Foresliadowing of ventral bevelling with slight indication of dorsal margin. Phase 3:-Progressive obliteration of ridge and furrow system with increasing definition of dorsal margin and commencement of ventral rarefaction (bevelling). Age 25-26. Phase 4:-Con1pletion of definite dorsal margin, rapid increase of ventral rarefaction and commencing delimitation of lower extremity. Age 27-30. Phase 5:-Commencing formation of upper extremity with increasing definition of lower extremity and possibly sporadic attempts at formation of ventral rampart. Phase 6:-Development and practical completion of ventral rampart with increasing definition of extremities. Phase 7:-Changes in symphysial face and ventral aspect of pubis consequent upon diminishing activity, accompanied by bony outgrowths into pelvic attachments of tendons and ligaments. Phase 8:-Smoothness and inactivity of symphysial face and ventral aspect of pubis. Oval outline and extremities clearly defined but no "rim" formation or lipping. Age 45-50. Phase 9 :-Development of "rim" on symphysial face with lipping of dorsal and ventral margins. Age 50 and upwards. Phase 10:-Erosion of and erratic, possibly pathological osteophytic growth on symphysial face with breaking down of ventral margin.

Paleodemography of the Carlston Annis (Bt‐5) Late Archaic skeletal population

“…This implies that had the 0s pubis been the sole criterion in this study, as has often been the case in many earlier paleodemographic surveys, approximately 60% of potentially ageable adults would have been excluded from the analysis. Regardless of which pubic symphyseal aging technique one prefers (Todd, 1921;McKern and Stewart, 1957;Gilbert and McKern, 1973;Hanihara and Suzuki, 1978;Meindl et al, 1985b;Katz and Suchey, 19861, this circumstance would clearly represent an unacceptable demographic sampling of a skeletal population under study. It is clear that the use of multiple age criteria has an additional benefit in that it provides a superior demographic sampling of a popula- tion under study.…”

“…In contrast, 31.7%, of Bt-5 adults lived in excess of 40 years, and only 29.8% were classified in the 25-35 year age interval. It is highly robable that the tions would be more concordant if Johnston and Snow (1961) had used the available Todd (1921) The extent to which taphonomic factors may have affected sampling of Indian Knoll adult age indicators, and the sex distribution of those individuals included in the study must also be considered. For example, the frequency with which adult age indicators were preserved, recovered, and made available for the Bt-5 skeletal series is summarized in Table 8.…”

“…These include 1) metamorphosis of the auricular surface of the ilium as determined by modal standards reported for criterion (Lovejoy et al, 1985131, 2)metamorphosis of the 0s pubis accordin to recently revised Todd age standards (To&, 1921;Meindl et al, 1985b), radiographic assessment of 3) proximal femur and 4) clavicle a e-related atterns of ting, 1977;Walker and Lovejoy, 19851, and 5 ) population-specific rates of functional dental wear. Sexes were combined and seriated as a composite sample for the a e criteria 0s pubis, auricular surface, an$ dental wear.…”

“…Assessment of sex was augmented by metric analysis (Dittrick and Suchey, 1986). Given that the sample used was restricted to mature (or mostly mature) individuals, age was assessed using primarily pubic symphysis remodeling (Todd, 1920(Todd, , 1921Katz and Suchey, 1986;Brooks and Suchey, 1990), as well as auricular surface remodeling , and in a few cases that lacked intact pelves (for the UCB portion of the sample), ectocranial cranial suture closure . For the adolescents and young adults, age at death was evaluated primarily on the basis of later stages of epiphyseal union.…”

“…El dimorfismo sexual de la pelvis también fue analizado de acuerdo con el método propuesto por Bruzek (2002). Para la estimación de la edad de muerte se analizaron los cambios morfológicos de la superficie auricular (Lovejoy et al 1985;Osborne et al 2004) y de la sínfisis púbica (Brooks y Suchey 1990;Suchey y Katz 1998;Todd 1921), y en ausencia de ellos, se observó el estado de obliteración de las suturas craneales (Meindl y Lovejoy 1989). Para el sacro se tuvo en cuenta el grado de fusión de las vértebras (Krogman e Isçan 1986 …”
