In the central-southeastern area of Buenos Aires Province, Argentina, lies a mountainous area of low height in Tandilia that contains important outcrops of quartzite and granite. A large number of buildings are made of massive blocks of rock, some of them with a surface of over 1 ha. In addition to these completely artificial constructions are other structures that are semi-natural, having been made in places with special topographical characteristics and complemented with dry-stone walls. Scanty written documents allow us to attribute some of the constructions to an age before the permanent settlement of the Creole population. In the Tandilia Sierras these structures are commonly known as "corrales de indios" (Indian corrals). This designation involves a double prejudice with regard to function and cultural affiliation. Out of a total of 22 structures, we analyze a group of 4 that were excavated to use to review the written documents.

This paper is about the research on the Historical Archaeology we have carried out for over more than a decade at Vuelta de Obligado Site, San Pedro, northeast of the Province of Buenos Aires. Our objectives are to know the dynamics of the strategy followed in the battlefield by the two groups who fought: Anglo-French and Argentine, and the results produced by a set of agents of formation and transformation of the archaeological record. To compare the stated expectations, we have used several sources of information: archaeological record, written documents, Argentine and European plans and sketches as well as the data provided by the present inhabitants. We have considered several, which are specified and used in our research. Finally, we have taken into account various perspectives, with regard to the objectives and stated hypothesis.

Se presentan los resultados del análisis zooarqueológico de los restos de fauna menor que forman parte de los conjuntos arqueofaunísticos hallados en contextos urbanos y rurales del siglo XIX en la ciudad y provincia de Buenos Aires. La muestra analizada proviene de los sitios históricos urbanos Casa Fernández Blanco (Ciudad de Buenos Aires), Casa Ameghino 1 (ciudad de Luján) y rurales Siempre Verde (partido de Benito Juárez), Santa Rosa (partido de Tandil). Se evalúa su presencia, y se diferencia dentro del conjunto arqueofaunístico aquellos taxones y/o partes esqueletarias que ingresaron al sitio por causa de agentes tafonómicos o procesos de formación postdepositacionales de aquellos producto de actividades antrópicas. Finalmente, se discute qué rol cumplieron en la alimentación u otro tipo de actividad cultural los restos de fauna menor que ingresaron a los sitios por causas antrópicas. Se compara su importancia intrasitio en relación con los otros taxones presentes y entre contextos urbanos y rurales. Además se considera la información proveniente de los documentos escritos y visuales con la finalidad de presentar un análisis más integral.
