Busca, por un lado, construir saberes disciplinares acerca de la subsistencia, la alimentación y los conceptos y métodos para abordarlas. Por otro lado, se propone poner en discusión las concepciones arqueológicas tradicionales sobre la subsistencia y la alimentación. El libro consta de dos partes. La primera parte introduce al lector en los aspectos más generales, teóricos y metodológicos sobre la subsistencia y la alimentación en arqueología. La segunda parte del libro se centra en las principales etapas de la secuencia de producción de alimentos.

This area presents abundant lithic raw materials of very good quality for knapping including flint, chalcedony and silicified wood. These raw materials were used by the inhabitants of the region since the end of the Pleistocene until recent historical times. Besides, we have recorded the exploitation of exotic stones in low proportions at the archaeological sites. Among these, the most abundant is obsidian which probably comes from sources located more than125 kmaway. In this context, the use of this type of raw material should be evaluated in terms of social and symbolic issues.In this paper, we examine the strategies of acquisition and reduction of the obsidian found at the archaeological sites Cerro Tres Tetas 1, Casa del Minero 1, Cueva de La Ventana, La Mesada and Cueva Túnel.

Para tener un acercamiento inicial al paisaje del área, realizamos prospecciones que incluyeron transectas sistemáticas, recorridos asistemáticos y relevamientos de arte rupestre. Estas tareas nos permitieron identificar rasgos significativos del paisaje-incluyendo la disponibilidad y distribución de recursos-, evaluar la presencia y localización de sitios al aire libre y reparados con arte rupestre y determinar la densidad y distribución de restos en superficie. Así, reconocimos características atractivas del paisaje para las sociedades pasadas. La distribución de restos líticos y del arte rupestre evidencian que este paisaje fue poblado con una intensidad media, aunque presentando variabilidad entre sectores. Asimismo, la distribución de fuentes y artefactos líticos da cuenta de que las tareas de manufactura identificadas a través de la localidad implicaron habitualmente el traslado de las materias primas hacia los lugares de producción.

We carry out a technomorphological analysis of the obsidian remains from these sites. Results from this work strengthen the idea that the groups which lived in the Central Plateau knew about and exploited an obsidian source known as Pampa del Asador. A raise in the use of this raw material throughout time is recorded, reaching its peak in the late Holocene. We identified two different moments in the exploitation of obsidian at the regional level. During the final Pleistocene and early Holocene, obsidian would not have played a relevant role in the organization of technology. Production sequences indicate that tools probably were entered to the sites already manufactured. During the middle and late Holocene nodules and cores could have been brought into the sites. The strategies involved in their reduction are in broad terms similar to those implemented with local raw materials; there is no evidence that obsidian had more value in any way. On the other hand, it is also not possible to state that there was just an eventual exploitation of this raw material. We believe that obsidian was acquired during mobility circuits which enabled the contact between different groups.

They have been exploited by hunter–gatherer societies since the latest Pleistocene until the Late Holocene. The study of their distribution, availability, and ways of exploitation at the quarries, together with the information stemming from the archaeological sites, enable the understanding of the first stages of tool production and consumption.
In this paper, two quarries from La María Archaeological Locality (Cantera de Sílex de CDM and Cantera Bosque Petrificado) are studied and compared. Their geomorphologic location is described. The lithological characteristics of the outcrops, the size of the stones, and the variability of raw materials available at them are also addressed. The accessibility and visibility of the quarries are analyzed. The way raw materials were exploited at the sources is evaluated taking into consideration their relationship with the local and regional structure of lithic resources. The information generated for the quarries is complemented and compared with the local trends identified for the habitation sites. This enabled the formulation of a general model about the first stages of production.
Although the quarries have different types of raw materials (flint and silicified wood), results show that similar technological strategies were implemented in them. These are in agreement with the general trend at the local and regional levels. Both sources are easily accessible from the surrounding landscape. They are visible from nearby areas. Probably, they were exploited mainly from nearby sites. At the quarries, the first stages of tool production were performed: core decortication and preparation and the production of blanks. The acquisition of raw material involved the selection of good quality nodules and boulders and the production of polyhedral cores knapped in multiple directions. These cores could be transported to the habitation sites or could be discarded in situ while still presenting active platforms. On the other hand, differences in some procurement practices might be related to decisions and variations linked to the particular characteristics of the resources in both outcrops.

Nevertheless, the identity of this community has been shaped mainly around two historical milestones: the arrival of Magellan in 1520 and the foundation of the city in 1901 by “pioneers”, mostly of European origin. That is to say, among the notions about the past there is a hegemonic position which places in the foreground eurocentric ideas, usually overlooking the cultural productions of the native groups. Hence, a large part of the indigenous past tends to be invisibilized. Social communication and education make it possible to problematize the representations set in a society. Based on the ideas above mentioned, and after establishing bonds with different social actors from the town, we have built a strategy of action research which has enabled us to understand the way in which the past is regarded in the area. One of the tasks has been the development of archaeology workshops in primary schools. In these workshops we have: inquired about how the first inhabitants of Patagonia are perceived in the regional imaginary; sought to problematize together with the students local constructions involving historical and cultural heritage; and tried to denaturalize frozen conceptions about the human past. In this article we present the different ways in which we have established and kept this bond with the community. We focus on the theoretical and methodological approach applied in the workshops. Finally, we reflect on the importance of working together with multiple social actors as a means to make visible and to place more social significance on the indigenous past of the area.

Desde hace 15 años llevamos adelante estudios sistemáticos sobre las fuentes de materias primas halladas allí. En este trabajo los objetivos son dar a conocer una síntesis de los procedimientos metodológicos aplicados, presentar la estructura de recursos de la localidad y discutir las estrategias de aprovisionamiento y explotación de rocas implementadas en canteras. En La María afloran –en más del 50% de su área– formaciones geológicas que presentan gran abundancia de rocas de muy buena calidad para la talla. Las fuentes son visibles y fácilmente accesibles. Las características de los restos indican que las sociedades pasadas tuvieron una intensa actividad de talla en las canteras, donde prepararon los núcleos y se obtuvieron formas base. Asimismo, no desarrollaron estrategias que optimicen el rendimiento de las materias primas. Esto es esperable en paisajes con alta disponibilidad como La María.
The landscape of the southern section of the central plateau of Santa Cruz -and specifically La María Archaeological Locality- is plenty of rocks. We have performed systematic analyses of raw material sources from La María for 15 years. The aim of this paper is threefold: to present a methodological synthesis, to communicate the structure of lithic resources of the locality and to discuss the strategies of acquisition and exploitation of raw materials applied in local quarries. More than 50% of the surface of La María is covered by geological formations with abundant stones of very good quality for knapping. Sources are visible and easy to access. The characteristics of the lithic remains indicate that past societies used these quarries intensively. There, they shaped cores and produced blanks. Strategies aiming at optimizing the performance of raw materials were not applied. This is something to be expected in a landscape with high availability of raw materials such as La María.

Las exposiciones fueron realizadas en un fructífero marco de discusión de propuestas teóricas, planteos metodológicos, y casos de estudio, que dieron como resultado los siete trabajos aquí publicados. Los estudios permiten establecer una serie de ejes temáticos que exponen intereses de investigación orientados a la caracterización arqueológica y geológica de fuentes de materias primas, a evaluar los avances generados desde diversas aproximaciones metodológicas, y otros destinados a indagar acerca de las estrategias de producción, intercambio e interacción implementadas por los pueblos en el pasado.

from the archaeological localities of La Maríaand Cerro Tres Tetas(Central Plateau of Santa Cruzprovince, Argentina).
Technomorphologic, functional and geochemical analyses of the obsidian remains from these localities were carried out.
Results show that obsidian comes from Pampa del Asador a source located over 125 km from the sites. Two chronological
moments in the exploitation of this raw material were identified with an increase in consumption over time. During the Final
Pleistocene/Early Holocene, obsidian was not a significant resource in the technological organization. Production sequences
indicate that tools may have arrived already manufactured to the sites. In contrast, in the Middle and Late Holocene, cores
and/or nodules were brought to the localities. Production strategies are similar to the ones recorded for local raw materials.
There is no evidence to indicate that obsidian was a more valued resource than local rocks. We cannot ascertain that obsidian
acquisition was part of a sporadic exploitation strategy from the source region. We believe that this raw material was obtained
in mobility circuits and from intergroup contact.
RESUMEN: En este trabajo examinamos las estrategias de aprovisionamiento, explotación, circulación y consumo de la obsidiana hallada en sitios de las localidades arqueológicas La María y Cerro Tres Tetas (Meseta Central de Santa Cruz, Argentina). Llevamos a cabo el análisis tecnomorfológico, funcional y geoquímico de los restos de esta materia prima. Los resultados indican que la obsidiana procede de Pampa del Asador, fuente distante a más de 125 km. Se registró un aumento de la explotación de esta materia prima a través del tiempo, identificándose dos grandes momentos. Durante el Pleistoceno Final/Holoceno Temprano, la misma no habría jugado un rol relevante en la organización tecnológica. Las secuencias de producción se caracterizan por el ingreso a los sitios de artefactos probablemente ya manufacturados. Durante el Holoceno Medio y Tardío se habrían ingresado a las localidades nódulos y/o núcleos. Las estrategias involucradas en su manufactura concuerdan en general con las implementadas para litologías locales y no exponen elementos que indiquen una mayor valorización de la obsidiana. No es
posible asociar la gestión de esta roca a una estrategia de explotación eventual. Consideramos que la materia prima se obtenía en el marco de circuitos de movilidad y contactos intergrupales.

Los primeros estudios de las manifestaciones rupestres en esta localidad fueron realizados por Gradin y Aguerre en 1983, quienes relevaron cinco cuevas pintadas. Posteriormente a finales de la década de 1990 Rafael Paunero amplía el relevamiento e identifica otras cuatro cuevas con arte rupestre, aunque dicha información no ha sido presentada de forma sistemática hasta el momento. En 2019 retomamos las investigaciones, con la intención de georreferenciar, relevar detalladamente y fotografiar los sitios ya conocidos y localizar nuevos sitios. Para ello, efectuamos prospecciones en distintos sectores del paisaje, buscando reconocer cuevas y aleros con pinturas rupestres. El objetivo de este trabajo es profundizar la caracterización de las manifestaciones rupestres de la localidad La Evelina. Se presentan las tareas de campo realizadas por nuestro equipo en las campañas de 1998, 1999 y 2019, describiendo la metodología utilizada para el relevamiento. Posteriormente, se detalla la muestra analizada y se exploran los patrones de distribución de las representaciones rupestres a distintas escalas. A su vez, se revisa la tipología de motivos propuesta por Gradin y Aguerre y se la compara con la empleada en otros sitios de la región. Por último se comunican los resultados del análisis en laboratorio: la cuantificación, caracterización y ubicación del repertorio rupestre de La Evelina. El análisis del arte rupestre de esta localidad y su integración con localidades cercanas permite una aproximación regional a la comprensión de las manifestaciones rupestres realizadas por las sociedades cazadoras-recolectoras del sur de la Meseta Central de Santa Cruz.

Por lo general, estas se ubican en afloramientos ignimbríticos de la Formación Chön Aike que delimitan cañadones. La María destaca por presentar gran diversidad en los tipos de motivos, en las técnicas de ejecución y en los colores empleados. Se ha sugerido que estas manifestaciones fueron realizadas durante una larga historia ocupacional del área, iniciándose a fines del Pleistoceno y llegando hasta el Holoceno tardío. Se propuso la existencia de tres grupos estilísticos con características diferentes. El grupo 1 incluye negativos de manos, escenas naturalistas, puntos y líneas. El grupo 2 presenta guanacos, círculos concéntricos, óvalos y negativos de manos. En el grupo 3 los motivos son geométricos esquemáticos, rectilíneos y en zigzag. Se mantienen los negativos de manos y se desarrolla el estilo de pisadas. No obstante, hasta el momento no se habían registrado motivos grabados en la localidad, a pesar de que en otras áreas de la región son abundantes. Aquí comunicamos los primeros hallazgos de este tipo. Se trata de guanacos y líneas, realizados sobre bloques desprendidos de un manto de basalto, que se ubican al noreste de la Laguna Grande de La María. Este sector presenta ocupaciones redundantes y de alta intensidad, que se evidencian en áreas de acampe y fuentes de materia prima lítica. Realizamos una descripción de los soportes utilizados, los motivos, las técnicas empleadas y la ergología asociada. Asimismo, evaluamos el estado de conservación y las posibilidades de identificar nuevos paneles en el futuro. Por último, pondremos en diálogo este nuevo registro con las características del paisaje arqueológico circundante.

In this paper, two quarries from La María Archaeological Locality (Cantera de Sílex de CDM and Cantera Bosque Petrificado) are studied and compared. Their geomorphologic location is described. The lithological characteristics of the outcrops, the size of the stones, and the variability of raw materials available at them are also addressed. The accessibility and visibility of the quarries are analyzed. The way raw materials were exploited at the sources is evaluated taking into consideration their relationship with the local and regional structure of lithic resources. The information generated for the quarries is complemented and compared with the local trends identified for the habitation sites. This enabled the formulation of a general model about the first stages of production.
Although the quarries have different types of raw materials (flint and silicified wood), results show that similar technological strategies were implemented in them. These are in agreement with the general trend at the local and regional levels. Both sources are easily accessible from the surrounding landscape. They are visible from nearby areas.

These cores could be transported to the habitation sites or could be discarded in situ while still presenting active platforms. On the other hand, differences in some procurement practices might be related to decisions and variations linked to the particular characteristics of the resources in both outcrops.

Probably, they were exploited mainly from nearby sites. At the quarries, the first stages of tool production were performed: core decortication and preparation and the production of blanks. The acquisition of raw material involved the selection of good quality nodules and boulders and the production of polyhedral cores knapped in multiple directions. These cores could be
transported to the habitation sites or could be discarded in situ while still presenting active platforms. On the other hand, differences in some procurement practices might be related to decisions and variations linked to the particular characteristics of the resources in both outcrops.
In this paper, two quarries from La María Archaeological Locality (Cantera de Sílex de CDM and Cantera Bosque Petrificado) are studied and compared. Their geomorphologic location is described. The lithological characteristics of the outcrops, the size of the stones, and the variability of raw materials available at them are also addressed. The accessibility and visibility of the quarries are analyzed. The way raw materials were exploited at the sources is evaluated taking into consideration their relationship with the local and regional structure of lithic resources. The information generated for the quarries is complemented and compared with the local trends identified for the habitation sites. This enabled the formulation of a general model about the first stages of production.

Social communication and education make it possible to problematize the representations set in a society. Based on the ideas above mentioned, and after establishing bonds with different social actors from the town, we have built a strategy of action research which has enabled us to understand the way in which the past is regarded in the area.
One of the tasks has been the development of archaeology workshops in primary schools. In these workshops we have: inquired about how the first inhabitants of Patagonia are perceived in the regional imaginary; sought to problematize together with the students local constructions involving historical and cultural heritage; and tried to denaturalize frozen conceptions about the human past.
In this article we present the different ways in which we have established and kept this bond with the community. We focus on the theoretical and methodological approach applied in the workshops. Finally, we reflect on the importance of working together with multiple social actors as a means to make visible and to place more social significance on the indigenous past of the area.
The landscape of the southern section of the central plateau of Santa Cruz -and specifically La María Archaeological Locality- is plenty of rocks. We have performed systematic analyses of raw material sources from La María for 15 years. The aim of this paper is threefold: to present a methodological synthesis, to communicate the structure of lithic resources of the locality and to discuss the strategies of acquisition and exploitation of raw materials applied in local quarries. More than 50% of the surface of La María is covered by geological formations with abundant stones of very good quality for knapping. Sources are visible and easy to access. The characteristics of the lithic remains indicate that past societies used these quarries intensively. There, they shaped cores and produced blanks. Strategies aiming at optimizing the performance of raw materials were not applied. This is something to be expected in a landscape with high availability of raw materials such as La María.
from the archaeological localities of La Maríaand Cerro Tres Tetas(Central Plateau of Santa Cruzprovince, Argentina).
Technomorphologic, functional and geochemical analyses of the obsidian remains from these localities were carried out.
Results show that obsidian comes from Pampa del Asador a source located over 125 km from the sites. Two chronological
moments in the exploitation of this raw material were identified with an increase in consumption over time. During the Final
Pleistocene/Early Holocene, obsidian was not a significant resource in the technological organization. Production sequences
indicate that tools may have arrived already manufactured to the sites. In contrast, in the Middle and Late Holocene, cores
and/or nodules were brought to the localities. Production strategies are similar to the ones recorded for local raw materials.
There is no evidence to indicate that obsidian was a more valued resource than local rocks. We cannot ascertain that obsidian
acquisition was part of a sporadic exploitation strategy from the source region. We believe that this raw material was obtained
in mobility circuits and from intergroup contact.
RESUMEN: En este trabajo examinamos las estrategias de aprovisionamiento, explotación, circulación y consumo de la obsidiana hallada en sitios de las localidades arqueológicas La María y Cerro Tres Tetas (Meseta Central de Santa Cruz, Argentina). Llevamos a cabo el análisis tecnomorfológico, funcional y geoquímico de los restos de esta materia prima. Los resultados indican que la obsidiana procede de Pampa del Asador, fuente distante a más de 125 km. Se registró un aumento de la explotación de esta materia prima a través del tiempo, identificándose dos grandes momentos. Durante el Pleistoceno Final/Holoceno Temprano, la misma no habría jugado un rol relevante en la organización tecnológica. Las secuencias de producción se caracterizan por el ingreso a los sitios de artefactos probablemente ya manufacturados. Durante el Holoceno Medio y Tardío se habrían ingresado a las localidades nódulos y/o núcleos. Las estrategias involucradas en su manufactura concuerdan en general con las implementadas para litologías locales y no exponen elementos que indiquen una mayor valorización de la obsidiana. No es
posible asociar la gestión de esta roca a una estrategia de explotación eventual. Consideramos que la materia prima se obtenía en el marco de circuitos de movilidad y contactos intergrupales.
El objetivo de este trabajo es profundizar la caracterización de las manifestaciones rupestres de la localidad La Evelina. Se presentan las tareas de campo realizadas por nuestro equipo en las campañas de 1998, 1999 y 2019, describiendo la metodología utilizada para el relevamiento. Posteriormente, se detalla la muestra analizada y se exploran los patrones de distribución de las representaciones rupestres a distintas escalas. A su vez, se revisa la tipología de motivos propuesta por Gradin y Aguerre y se la compara con la empleada en otros sitios de la región. Por último se comunican los resultados del análisis en laboratorio: la cuantificación, caracterización y ubicación del repertorio rupestre de La Evelina. El análisis del arte rupestre de esta localidad y su integración con localidades cercanas permite una aproximación regional a la comprensión de las manifestaciones rupestres realizadas por las sociedades cazadoras-recolectoras del sur de la Meseta Central de Santa Cruz.
La María destaca por presentar gran diversidad en los tipos de motivos, en las técnicas de ejecución y en los colores empleados. Se ha sugerido que estas manifestaciones fueron realizadas durante una larga historia ocupacional del área, iniciándose a fines del Pleistoceno y llegando hasta el Holoceno tardío. Se propuso la existencia de tres grupos estilísticos con características diferentes. El grupo 1 incluye negativos de manos, escenas naturalistas, puntos y líneas. El grupo 2 presenta guanacos, círculos concéntricos, óvalos y negativos de manos. En el grupo 3 los motivos son geométricos esquemáticos, rectilíneos y en zigzag. Se mantienen los negativos de manos y se desarrolla el estilo de pisadas.
No obstante, hasta el momento no se habían registrado motivos grabados en la localidad, a pesar de que en otras áreas de la región son abundantes. Aquí comunicamos los primeros hallazgos de este tipo. Se trata de guanacos y líneas, realizados sobre bloques desprendidos de un manto de basalto, que se ubican al noreste de la Laguna Grande de La María. Este sector presenta ocupaciones redundantes y de alta intensidad, que se evidencian en áreas de acampe y fuentes de materia prima lítica. Realizamos una descripción de los soportes utilizados, los motivos, las técnicas empleadas y la ergología asociada. Asimismo, evaluamos el estado de conservación y las posibilidades de identificar nuevos paneles en el futuro. Por último, pondremos en diálogo este nuevo registro con las características del paisaje arqueológico circundante.
