          Abstract

          La cerámica más temprana marca un hito en la historia humana de los Andes del sur. Este trabajo propone una aproximación de la edad de la cerámica más temprana mediante modelos cronológicos basados en la estadística bayesiana. En estos, se comparan 84 fechados radiocarbónicos y de termoluminiscencia de 49 sitios que abarcan dos áreas en Argentina dentro de las provincias de San Juan y Mendoza y tres áreas del norte semi-árido, centro y centro-sur de Chile. Los datos analizados indican un patrón llamativo de fechas similares en cuatro de las cinco áreas, con medianas entre 2100 y 2180 cal. AP (2250-1920, 68% probabilidad, límites iniciales), aunque algunos de los rangos de error son amplios. Se destaca la similitud de las fechas en una macrorregión que se extiende a lo largo de 1000 kilómetros (norte-sur) entre las 30° a 39°S y que contiene una gran variedad de ambientes. La coincidencia temporal resulta aún más llamativa porque el límite sur de agricultura en el continente Sudamericano se encuentra en estas áreas. Este trabajo pretende incentivar el interés de los investigadores en la excavación y el fechado de contextos relevantes y estimular las discusiones sobre la naturaleza de la adopción inicial de la cerámica en los Andes del sur.

          Translated abstract

          The earliest pottery marks a milestone in the human history of the southern Andes. This paper proposes an approximation of the date of the earliest pottery using Bayesian chronological models. Models of 84 radiocarbon and thermoluminescence dates from 49 sites are compared among five areas in Argentina (the provinces of San Juan and Mendoza) and Chile (the semi-arid north, central, and south central). Although there are still few data, they show an intriguing pattern of very similar dates with medians between 2100-2180 cal BP (2250-1920, 68% probability, starting boundaries) in four of the areas, though some error ranges are large. The similarity of the dates is striking considering that the macro-region extends over one thousand kilometers (north-south) from 30° to 39°S and includes a diverse range of environments. The contemporaneity is even more notable because these areas include the continent's southern limit of agriculture. It is hoped this will encourage researchers to more carefully assess this period when excavating and dating relevant contexts as well as encourage discussions on the nature of the initial adoption of ceramics in the southern Andes.

              Rolling Out Revolution: Using Radiocarbon Dating in Archaeology

              Sixty years ago, the advent of radiocarbon dating rewrote archaeological chronologies around the world. Forty years ago, the advent of calibration signaled the death knell of the diffusionism that had been the mainstay of archaeological thought for a century. Since then, the revolution has continued, as the extent of calibration has been extended ever further back and as the range of material that can be dated has been expanded. Now a new revolution beckons, one that could allow archaeology to engage in historical debate and usher in an entirely new kind of (pre)history. This paper focuses on more than a decade of experience in utilizing Bayesian approaches routinely for the interpretation of 14 C dates in English archaeology, discussing both the practicalities of implementing these methods and their potential for changing archaeological thinking.
