Abstract
Dental morphological trait expressionshave been used in anthropology and forensic sciences fordetermination of biological and geographical affiliations.The present study was carried out with a Chubut preconquestsample from Patagonia, Argentina. 18 skullswith partial dentitions from Chubut (Patagonia) wereanalyzed. The ASU Dental Anthropology System wasused to register the expression grade of all dental traits.In spite of small sample sizes, we can conclude thatshovel shape (UI1, UI2), two lingual premolar cusps(UP1, UP2), and hypocone (UM1, UM2) frequenciessuggest a Mongoloid (Sinodont) origin.

Values exceeding 70% were found for six traits—all in the upper arcade; these are shovel shape (UI1, UI2), two Correspondence to: Carlos David Rodríguez-Flórez, Grupo de Investigaciones ARQUEODIVERSIDAD, Universidad del Valle - ColombiaDepartamento de Antropología y Sociología, Universidad de Caldas Colombia E-mail: bioarqueologia@ucaldas.edu.co
Traits with frequencies between 10 and 69% were found for 12 traits: shovel shape (LI1, LI2, UC, LC), double shovel (UI1, UI2), tuberculum dentale (UI1, UI2, UC), interruption groove (UI2), two lingual premolar cusps (LP2), and metaconulid (LM1)
Summary
Dental morphological trait expressions have been used in anthropology and forensic sciences for determination of biological and geographical affiliations. The analysis of biological relatedness using dental nonmetric traits has been helpful even in commingled samples when standardized procedures are followed (Ullinger et al, 2005). For these reasons, reconstruction of biological relationships among ancient human groups using teeth is an important research problem for South American bioarcheologists. The present study was carried out with a Chubut human pre-conquest sample from Patagonia, Argentina, with the aim of exploring dental morphological dental patterns in this group (Fig. 1). The objective of this article is to describe the presence of 40 dental nonmetric traits in this pre-conquest sample from the Chubut
