In the following work we delve into the scientific, technical and also political context of the last excavation directed by Alberto Rex González at the Pucará de Andalgalá, prior to the coup d’état of March 24, 1976. The trigger for this analysis results from the discovery of materials from that campaign stored in the Archaeolo-gy División of La Plata Museum. Through historical reconstruction based on the review of documents and bibliographic references, interviews and analysis of the material recovered from the archeology division this article aims to explain how Alberto Rex González designed the field work, the context in which the campaign took place, what previous ideas led him to undertake the project and what could have been the reasons for abandoning it
This paper presents the results of the quantitative and taphonomic study of the archaeofaunal materials belonging to the Mammalia Class, coming from the Isla El Disparito site (Iberá System, Corrientes). The study area is dated to 1000 years BP. The taphonomic characteristics observed indicate that various natural variables acted on the bone complex, but do not allow us to infer that they were responsible for its accumulation, unlike anthropic agents. Furthermore, a greater proportion of the recorded variables linked to the dynamics of the markedly hydrophilic depositional environment in which the materials were deposited. The results also indicate that species dependent on the fluvial environment, especially those of small to medium size (-i.e. rodents), would have been the most exploited during the late Holocene by the hunter-gatherer-fisher groups settled in the sector under study. Among them, the presence of specimens corresponding to Myocastor coypus (Molina, 1782) was highlighted.
This paper integrates human ecology and evolution into practices and reflections that are foundational to sociocultural anthropology. It problematizes protected natural areas in Argentina by discussing: a. the discourses that isolate them from the surrounding regional and ecological context, turning them into “islands” of biodiversity, and b. the historical relationship between these areas and Indigenous communities. The theoretical basis of this work lies in Niche Construction Theory and Actor-Network Theory, analyzing the case of the Potae Napocna Navogoh community and the Río Pilcomayo National Park. In conclusion, emerging tensions and challenges from this context are identified, and the strategies and policies necessary to promote collaboration and dialogue among all involved parties are addressed.
The development of mining in La Rioja from the colonial period to its peak in the 19th century left numerous remains of facilities that drove the activity, especially in the Famatina region, but these have not been the subject of systematic study. Between 2024 and 2025, as part of a CONICET research project, three archaeological campaigns were carried out in the ruins of the old Capayán smelter with the aim of surveying the preserved structures and collecting surface material. Analysis of both records identified a productive sector and a domestic one. The presence of foreign objects raised questions about the possible users and how they arrived in the region. Two alternatives were evaluated: one route from the Pacific, through the trans-Andean ports, and another from the Atlantic, where the railway would have played an important role as a means of transport.
