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.
