R e s u m e n Se analiza el primer registro confiable de un perro prehispánico (Canis familiaris) recuperado en un sitio de cazadores recolectores del humedal del Paraná inferior (Argentina). Se discuten distintos aspectos relacionados con su origen, antigüedad y tipo de interacción que habrían establecido con las poblaciones humanas en el marco de la escasa información de la que actualmente disponemos acerca de su presencia entre los grupos cazadores-recolectores del extremo sur de Sudamérica.

The First Record of a Pre-Columbian Domestic Dog (Canis lupus familiaris) in Brazil AbstractArchaeological excavations of the PSG-07 earthen mound at Pontal da Barra in Rio Grande do Sul, southern Brazil have revealed the earliest known evidence for the presence of domestic dog (Canis lupus familiaris) in Brazil. This is the first reported pre-Columbian example in the country. Analysis of morphology, morphometry, and dental enamel laminae identified a left maxillary molar 1, left maxillary molar 2 and attached fragments of the maxilla of Canis lupus familiaris. A direct radiocarbon date on a fragment of the maxilla provided an age range between 1701 and 1526 cal BP (2σ). This is within the range of other dates for the site, which indicate intermittent occupation between 2024 and 1027 cal BP (2σ). Data from carbon isotope analysis indicates a potential marine diet. However, nitrogen isotope analysis values are lower than expected for a marine diet. The sparse records of preColumbian Canis lupus familiaris in the region emphasise the importance of the present work.
