I am a Research Fellow for the National Research Council of Argentina (Instituto Multidisciplinario de Historia y Ciencias Humanas, CONICET-IMHICIHU) and I hold a position as Assistant Professor of Prehistoric Technologies at the Departamento de Ciencias Antropológicas, Facultad de Filosofía y Letras, Universidad de Buenos Aires. I received my PhD in Archaeology from Universidad de Buenos Aires (2010). My main research interests are lithic taphonomy and technology. Since 2002, my research has focused on the actualistic and archaeological study of hunter-gatherer lithic assemblages recovered from Fuego-Patagonia (Southern South America).

This is particularly the case if postdepositional processes acting upon lithics include percussion and/or pressure mechanisms. Trampling is one of the most ubiquitous taphonomic processes in archaeological contexts, in particular surface loci. In this paper, we present a techno-morphological characterization of experimental lithic pseudotools produced by human treadage in order to contribute to the identification of the taphonomic background noise within different regions. Experimental artifacts were analyzed using the main classification methodology applied by lithic analysts in Argentina, to maximize the comparability of the outcomes of this research. Edge damage, stone tool type, flake scar size, flaking pattern, etc., are described. Trampling experiences included several raw materials represented within Pampa and Patagonia archaeological assemblages. It allowed us to explore variations within trampling effects on different rocks and substrates as well as to generate expectations on the contribution of pseudotools to the archaeological assemblages.
Resumen La acción de los procesos tafonómicos sobre litos naturales o artefactos puede generar pseudomorfos de instrumentos líticos. Esto es particularmente cierto para los procesos postdepositacionales que incluyen a los mecanismos de percusión y presión en su funcionamiento. Entre ellos se encuentra el pisoteo, uno de los procesos tafonómicos más ubicuos en distintos contextos arqueológicos, especialmente aquellos de superficie. A fin de contribuir a la identificación del ruido de fondo tafonómico en diferentes regiones, en este trabajo realizamos la caracterización morfológica de pseudoinstrumentos líticos producidos experimentalmente por pisoteo humano. Para maximizar la comparabilidad de nuestros resultados, analizamos las piezas experimentales siguiendo la propuesta morfo-tipológica de uso más difundido en Argentina. Se describen el tipo de rastro complementario, grupos tipológicos, extensión de los filos, la anchura y patrón de los lascados, entre otros aspectos. Las experiencias incluyeron el pisoteo sobre sustrato duro y blando de piezas confeccionadas con una amplia variedad de materias primas líticas representadas en diversos conjuntos arqueológicos de Pampa y Patagonia. Ello permitió explorar las variaciones existentes en los efectos del pisoteo sobre distintas rocas y sustratos, así como generar expectativas sobre la contribución del ruido tafonómico a los conjuntos líticos bajo la forma de pseudoinstrumentos.

In this paper we present the first body of paleoecological and archaeological data for Cueva Huenul 1 site, recently excavated, which offers a sedimentary sequence extending during the last of 16.000 calendar years. Initially, we present a chrono-stratigraphic frame for the site, including new tephro-chronological information. On this basis, four temporal components are defined, providing the historical scheme for the analysis of the recovered evidences that include: archaeofaunas (paleontological and archaeological), archaeobotany, lithic and ceramic technology, and rockart. These results at a site scale provide a first approa...

As rocks are among the most durable raw materials employed by modern humans and their ancestors, differential preservation has conferred a leading role in archaeological research upon lithic artifacts. Indeed, lithics—flaked artifacts in particular—are the proxy for culture or anthropic presence most commonly used by scholars all over the world. This artifact-human relationship promoted actualistic research on flintknapping in archaeology but no similar effort was devoted to assessing alternative non-cultural (i.e. taphonomic) sources for flaked stone objects. Even though actualistic studies have already shown that taphonomic processes may produce lithic pseudomorphs, this fact is only rarely considered in archaeological practice and research design. Furthermore, it is commonly assumed that ...

If taphonomic processes and lithic raw material are in place, assessing the contribution of pseudo artifacts is a necessary step in a taphonomically oriented archaeological research design. This was the case at Casa de Piedra de Rosello 1 rockshelter (Chubut, Argentina), where chert from the bedrock is the dominant toolstone throughout the archaeological sequence. Research conducted at the site included in situ rockfall experiments, clast sampling, and techno-morphological analysis of both experimental and collected flaked specimens. It is concluded that although conditions for rockfall pseudo artifact production exist at CP1, its contribution to the overall lithic assemblage was negligible. Nevertheless, the impact of pseudomorphs on archaeological interpretations would be more important in stratigraphic units exhibiting low discard rate or no artifacts at all.

A través del estudio de la organización tecnológica y la estructura tecnológica regional se discuten las estrategias de uso del espacio y los factores que pueden haberlas influenciado en esta franja del interfluvio. El uso humano de laslagunas en bajos sin salida es revisado especialmente. Se concluye que los cazadores-recolectores habrían ocupado con mayor intensidad aquellos espacios del interfluvio que conjugan la disponibilidad de rocas de grano fino oscuras tipo Potrok Aike en forma abundante con la menor distancia a los cursos fluviales.This paper presents the technological information produced by a regional distributional study conducted withi...

We apply a data mining technique known as decision trees to experimental datasets obtained in several trampling experiments. Results show that the ratio of area to thickness is the main element affecting the probability of breakage on lithic artifacts by trampling. Also, a maximum thickness value for lithic artifacts prone to be broken by trampling is estimated. Finally, we argue establishing threshold values for trampling potential allows distinguishing incidental fractures with similar traits and different origins.Este trabajo presenta una propuesta para estimar el Potencial para la Fragmentación por Pisoteo (PFP) en artefactos líticos a partir de los atributos métricos de las piezas.

The petrographic characterization of natural and archaeological samples of those rocks is presented. In addition, their availability in the regional landscape is assessed through the systematic sampling of several secondary lithic sources. The comparison of the natural availability of these lithologies and their representation in the archaeological record shows that raw material selection was not primarily influenced by availability. Finally, we explore several criteria that may have been applied to raw material selection for bola manufacture and present the main technological patterns observed in the archaeological record.Este trabajo aborda el estudio de las materias primas líticas utilizadas por los cazadores-recolectores del norte de la isla Grande de Tierra del Fuego (Argentina) para la manufactura de bolas.

La costa es predominantemente baja alternada con acantilados o barrancas de escasa o mediana altura y amplias playas de grava y arena gruesa, intercaladas con cabos o puntas de mayor altura. Se caracteriza por un régimen macro mareal que expone amplios sectores de plataforma de abrasión. Esto significa que hay sectores donde la distancia de los sitios a la costa se redujo y sectores en los que se incrementó. Esta dinámica impone la necesidad de calibrar la medida clásica de ?distancia al mar? teniendo en cuenta el rango temporal de los sitios estudiados y la tasa de retroceso/acreción de la costa. Solo así es posible obtener una estimación de la distancia real de un locus a la línea costera durante sus ocupaciones. Por lo tanto, la distancia actual a la costa ofrece un valor mínimo o máximo, según el caso. De acuerdo con estas imposiciones ambientales, el trabajo de relevamiento se realizó mediante transectas paralelas a la línea de costa o siguiendo el contorno de barrancas altas cuando estas estaban presentes; en algunas localidades se seleccionaron geoformas donde se realizaron prospecciones dirigidas. Los recorridos se hicieron íntegramente a pie e incluyeron el registro de todos los hallazgos arqueológicos, según tres categorías: sitios, concentraciones y hallazgos aislados. Se realizó un trabajo no invasivo, con énfasis en el registro de los abundantes casos de sitios en riesgo. Durante los trabajos de campo se detectaron 81 loci arqueológicos, incluyendo sitios y concentraciones, de los cuales en 76 casos (93,8%) se observó algún tipo de perturbación.Fil: Borrero, Luis Alberto.

This research is part of a regional project aimed at the study of late Holocene coastal occupations of hunter-gatherers in northern Grande Island of Tierra de Fuego. The assemblages were collected from aeolian deflation hollows in the longitudinal sand dunes of the Chorrillos archaeological locality, a high energy sedimentary environment affected by strong winds. Taphonomic assessment reveals that aeolian abrasion of artifact surfaces is a reliable indicator for lithic assemblage exposure and stability thereof. Furthermore, different abrasion degrees show diverse flaking events and subsequent configurations. After techno-morphological and taphonomic analyses, several questions are posed about the recurrence of occupations in the locality, criteria of blank selection, the strategy of volume management, artifact versatility and, ultimately, the functionality of the place related to the marine resources exploitation.

Hunter-gatherers occupied the site discontinuously during the Early (Component 2) and Late Holocene (Component 4). A comparative analysis of the lithic assemblages assigned to these periods shows that although different in size, they are similar in artifact composition. Furthermore, the morpho-technological analysis suggests that the site was briefly and recurrently occupied, although discontinuously through time. The continuity in the composition of the lithic assemblages is interesting since both components represent different stages in the human peopling of Patagonia. We suggest that the location of CH1, near the Cerro Huenul obsidian quarry, coupled with the local absence of permanent water sources, may have conditioned this similar pattern of knapping activities and lithic discard at the site.

Resumen
La acción de los procesos tafonómicos sobre litos naturales o artefactos puede generar pseudomorfos de instrumentos líticos. Esto es particularmente cierto para los procesos postdepositacionales que incluyen a los mecanismos de percusión y presión en su funcionamiento. Entre ellos se encuentra el pisoteo, uno de los procesos tafonómicos más ubicuos en distintos contextos arqueológicos, especialmente aquellos de superficie. A fin de contribuir a la identificación del ruido de fondo tafonómico en diferentes regiones, en este trabajo realizamos la caracterización morfológica de pseudoinstrumentos líticos producidos experimentalmente por pisoteo humano. Para maximizar la comparabilidad de nuestros resultados, analizamos las piezas experimentales siguiendo la propuesta morfo-tipológica de uso más difundido en Argentina. Se describen el tipo de rastro complementario, grupos tipológicos, extensión de los filos, la anchura y patrón de los lascados, entre otros aspectos. Las experiencias incluyeron el pisoteo sobre sustrato duro y blando de piezas confeccionadas con una amplia variedad de materias primas líticas representadas en diversos conjuntos arqueológicos de Pampa y Patagonia. Ello permitió explorar las variaciones existentes en los efectos del pisoteo sobre distintas rocas y sustratos, así como generar expectativas sobre la contribución del ruido tafonómico a los conjuntos líticos bajo la forma de pseudoinstrumentos.

The assemblages were collected from aeolian deflation hollows in the longitudinal sand dunes of the Chorrillos archaeological locality, a high energy sedimentary environment affected by strong winds.
Taphonomic assessment reveals that aeolian abrasion of artifact surfaces is a reliable indicator for lithic assemblage exposure and stability thereof.
Furthermore, different abrasion degrees show diverse flaking events and subsequent configurations.
After techno-morphological and taphonomic analyses, several questions are posed about the recurrence of occupations in the locality, criteria of blank selection, the strategy of volume management, artifact versatility and, ultimately, the functionality of the place related to the marine resources exploitation.
This work presents the techno-morphological and taphonomic study of the cores from the open-air site San Genaro 3 – 4, located on the southern coast of San Sebastián Bay (Tierra de Fuego, Argentina). This research is part of a regional project aimed at the study of late Holocene coastal occupations of hunter-gatherers in northern Grande Island of Tierra de Fuego.
