Abstract

RETAMAL, Rodrigo; PACHECO, Aryel  and  URIBE, Mauricio. Dimorfismo sexual, distribución etaria y longevidad del cementerio Pica 8 (período Intermedio Tardío, 950-1450 DC, Norte Grande de Chile). Estud. atacam. [online]. 2012, n.44, pp.89-106. ISSN 0718-1043.  http://dx.doi.org/10.4067/S0718-10432012000200005.

The aim of this paper was to study the age, sex and longevity distributions of adult skeletons from Pica 8 skeletal collection (82 skeletons), belonging to the Pica Tarapacá Complex, Northern Chile. Regarding sex estimation, we utilized Buikstra and colleagues' method for the os coxae bone and Ferembach and colleagues' method for cranial estimation was utilized. With these methods sex was estimated for all the sample (35 males, 47 females). Concerning age estimation, Brooks and Suchey method for pubic symphysis and Lovejoy method for iliac auricular surface were utilized. Both methods showed similar estimations until 39 years old, but differed beyond this age. The presence of senile individuals in this cultural complex is discussed as it opens interesting venues of research about their cultural role. In this sense, it is important to complement the research with a paleo gerontologic focus and in general, a focus from the Anthropology of Aging, which could contribute more to understanding of this cultural complex.

Keywords : Pica Tarapacá Complex; sex estimation; age at death assessment; longevity.
