Our evidence shows that Larache served as a burial place for a diverse, yet culturally integrated and potentially elite segment of the Atacameño population, but not a foreign enclave as had been postulated.

Archaeology in San Pedro de Atacama (northern Chile) contributes significantly to our understanding of the Middle Horizon Tiwanaku polity, its iconography, regional interaction spheres, and other pivotal themes in Andean Studies. New AMS C14 dates, however, allow us to revisit San Pedro chronological phases and the associated ceramics that often define them. This paper extends previous important contributions to ceramic analysis in the area by presenting the ceramic material found in newly dated tombs and the temporal relationship of red, black, and grey polished vessels. The results suggest that these key San Pedro ceramic styles may be more contemporary in time than previously thought. Color variation may therefore be the result of different symbolic and contextual uses rather than temporal production developments. This leads to a reevaluation of the accepted phase structure as a linear sequence of key ceramic types and of the current understanding of cultural fluorescence during the late Formative and Middle Period (ca. AD 100-900).Key words: San Pedro de Atacama, chronology, ceramic styles, mortuary archaeology, seriation. La arqueología de San Pedro de Atacama (norte de Chile) contribuye fuertemente a nuestra comprensión del Horizonte Medio, el Estado de Tiwanaku, su iconografía, las redes de intercambio regional, y otros temas andinos centrales. Sin embargo, nuevas fechas radiocarbónicas AMS nos permiten retomar el tema de la cronología arqueológica local, sus fases, y los tipos cerámicos

Although Andean archaeology has long used the term “ethnic” to refer to human groups, new understandings of ethnicity have injected less static understandings of contextualized identity construction into our models of the past. A review of recent work on ethnicity in the field reveals, however, that methodological approaches to these social entities do not always follow suit and rather favor normative synchronie comparisons. This paper explores the origins and trends in the study of ethnic groups and ethnicity in Andean archaeology, arguing that we may be seeing the persistence of the culture concept in the guise of ethnicity. It also examines best practices in the literature in order to make recommendations concerning the adoption of local, contextual, and diachronic methods in conjunction with multiple lines of evidence. These practices are more likely to expose the processes of identity construction by rendering explicit the relationships among culture, ethnicity, and the use of emblemic material culture. It argues, thereby, for the provision of proof of this process rather than its assertion.
