In the Brazilian state of Rio Grande do Sul, the term cerrito was traditionally used to designate archaeological phenomena that emerge in the form of mounds in different landscapes. Except for recent research developed in the southwestern region of the Patos Lagoon, few advances have occurred since the 1980s in the study of cerritos in Brazil. This article presents an analysis of the lithic industries of sites with mounds in the southwestern region of the Patos Lagoon and in the central region in the current territory of Rio Grande do Sul. The results, along with other data from the sites, suggest that coastal sites were occupied by sedentary fisher-hunter-gatherers, who also possibly domesticated certain plants. Lithic material was scarce there and was mainly produced from pebbles and quartz cobbles using the anvil technique. In contrast, central region formations presented mounds on outcrops, using land, pebbles, and boulders; the area was occupied by a hunter-gatherer group that had projectile points and other instruments carved mainly by façonnage and débitage.

Los naufragios y parte desu carga continiian siendo objeto de actividades de salvamento y comercializaciόn, que traicionan los principios éticos de la conservatiόn e investigation del patrimonio cultural. Detrás del cumplimiento de ciertos estándares metodolόgicos, la participation de profesionales, el aval de algunos gobiernos y el aplauso del público, la principal motivatiόn de dichas actividades yace en la obtenciόn de un rádito econόmico, mediante la subasta de un acervo patrimonial no renovable. En este trabajo se expone una critica a los principios que rigen estas actividades, con especial atenciόn en los naufragios y las colecciones de monedas. Sobre la base de cuestiones eticas, epistemologicas y técnicas, se presentan los lineamientos fundamentales de un modelo centrado en la investigation, puesta en valor y preservatiόn a largo plazo de los artefactos.

Las enfermedades infecciosas fueron señaladas como la causa principal de muerte en las sociedades pasadas. Sin embargo, hasta el momento son escasos los conocimientos acerca del modo en que afectaron a las poblaciones humanas del sur de Sudamérica. El objetivo de este trabajo es estudiar el impacto que las enfermedades infecciosas tuvieron sobre las poblaciones de cazadores-recolectores que habitaron Patagonia Austral, a partir de la identificación, descripción e interpretación de lesiones óseas en restos humanos del Holoceno medio y tardío (aproximadamente 5200-100 años aP). Se analizaron macroscópicamente 54 individuos hallados en 50 sitios arqueológicos, sobre los cuales se describieron presencia, localización, lateralidad, tipo de formación de hueso nuevo (woven, lamelar, mixto) y distribución de las lesiones óseas. Se registraron lesiones diagnósticas y altamente compatibles con infecciones óseas en ocho (14,8%) individuos (sin diferencias entre sexos y edades), seis de los cuales (75,0%) provienen del sur de Tierra del Fuego. Cuatro individuos presentaron lesiones compatibles con osteomielitis y dos con tuberculosis (un no-adulto y un adulto). Esto último representa un hallazgo relevante para discutir la presencia de tuberculosis en poblaciones pasadas y su evolución en América. Los resultados presentados sugieren además que las evidencias de procesos infecciosos pueden ser recurrentes en análisis específicos sobre muestras esqueletales de cazadores-recolectores.

Understanding the complex relationships among social identities, long-distance exchange, and migration has long been an important issue in archaeology. In the central Andes, archaeologists have grappled with these issues to understand highland–coastal interaction. We present a case study of these relationships in the coca-growing zone of the Moche Valley (chaupiyunga zone, 200–1,200 m asl) during the Early Intermediate period (400 BC–AD 600). We focus on reconstructing the social identities of the people who lived at Cerro León, a large hill town situated astride an important access route into the chaupiyunga from the highlands. Unlike most sites in the chaupiyunga, the site is dominated by highland-style pottery. Petrographic analysis indicates that the sources of the highland-style pottery were in the adjacent highlands. Our analysis of daily domestic activities, vernacular architecture, personal adornment, and ritual practices, including burial practices, indicates that most of the residents of Cerro León were immigrants from the highlands. We argue that these immigrants produced and reproduced a distinctive highland (Culle) identity throughout the occupation of the site, which lasted 100 to 200 years. Evidence demonstrates that site residents had extensive exchange relationships with coastal Yunga communities in the lower and middle Moche Valley.

Este informe discute intentos iniciales por cultivar maíz con el uso de agua procedente de Hierve el Agua, y también evalúa los análisis de agua y los datos palinológicos disponibles en las terrazas de dicho sitio. La discusión se extiende también a la toxicidad de boro en el sitio, así como al origen de los minerales disueltos en el agua. Urge cooperación entre instituciones de México y en los Estados Unidos de Norteamérica con el motivo de experimentar con el cultivo de plantas en Hierve el Agua.

Andean prehispanic textiles are renown for being complex masterpieces made with labor-intensive techniques and high-quality raw materials. Nevertheless, the vast majority of textiles, those used by the population at large, were plain, simple, and without any decoration. We study a sample composed of the most common textiles used by people living at Cerro de Oro in the Cañete Valley, Peru. Our analysis focuses on fiber selection, yarn thickness, and the presence of errors throughout the process of weaving. We discuss relevant aspects of the social process of textile production, such as the role played by plain-weave textiles in different contexts, their use in different types of garments, and the varied ways community members, with particular skill levels, participated in clothing the living and the dead at Cerro de Oro.

Recent archaeological fieldwork on Isla de Mona in the Caribbean has led to the discovery of a substantial corpus of early colonial inscriptions inside the darkzone of one of the 200 cave systems on the island. Cave 18, like multiple others on Isla de Mona, was a well-established indigenous spiritual realm in the centuries leading up to European colonization. Christian symbols, individual names, written dates, and Spanish and Latin religious commentaries are located in direct association with preexisting indigenous iconography and activities. This paper applies paleographic (handwriting) analysis to establish the authenticity, authorship, and chronology of the inscriptions and to interpret the nature of this early spiritual encounter. We conclude that these sixteenth-century inscriptions represent visits to the cave by first-generation Europeans, including Spanish royal officials in Puerto Rico, and reflect their reactions to native religious landscapes. The inscriptions on Isla de Mona capture personal, face-to-face encounters with native religion and represent Christian commentaries and reactions to indigenous spaces and worldview in the early colonial period.

Investigations at sites across northwestern Honduras—inside and outside the Maya area—have revealed diverse food activities and ingredients. Paralleling the evidence from durable artifact assemblages, we see transformation over time in materials and practices, as well as the movement of elements across the landscape. Botanical evidence points toward a dynamic overlap between northern and southern societies, with northwestern Honduras serving as a sort of regional crossroads. In this article, we compare cuisines from several ancient communities in northwestern Honduras, using microbotanical and macrobotanical residues. We briefly address the political and historic context of the region and provide abridged biographies of several culinary taxa. Of particular interest are milpa annual crops such as maize and squash, managed and cultivated palm species, wild and managed herbaceous species, edible fruit species, and root and tuberous crops such as lerén, sweet potato, and manioc.

We present an AMS radiocarbon date from a bird image in a cave on the island of Hispaniola in the northern Caribbean. Borbón Cave No. 1 contains a key rock art assemblage that likely reflects a significant part of past native Taíno societies’ symbolic thought and beliefs. The grouping has already served to define one rock art style in the Antilles: the Borbón School. Our sample yielded a date of 890 ± 30 BP (1045–1225 cal AD). This result, as well as additional published dates for the region, confirms that these images were created before European contact with the region. Further dating comparison indicates that Taíno artistic traditions persisted for some years after the arrival and settlement of Spanish colonists on the island.

In “How Can Spin, Ply, and Knot Direction Contribute to Understanding the Quipu Code?” (2005), mathematician Marcia Ascher referenced new data on 59 Andean khipus to assess the significance of their variable twists and knots. However, this aggregative, comparative impulse arose late in Ascher's khipu research; the mathematical relations she had identified among 200+ previously cataloged khipus were specified only at the level of individual specimens. This article pursues a new scale of analysis, generalizing the “Ascher relations” to recognize meaningful patterns in a 650-khipu corpus, the largest yet subjected to computational study. We find that Ascher formulae characterize at least 74% of khipus, which exhibit meaningful arrangements of internal sums. Top cords are shown to register a minority of sum relationships and are newly identified as markers of low-level, “working” khipus. We reunite two fragments of a broken khipu using arithmetic properties discovered between the strings. Finally, this analysis suggests a new khipu convention—the use of white pendant cords as boundary markers for clusters of sum cords. In their synthesis, exhaustive search, confirmatory study, mathematical rejoining, and hypothesis generation emerge as distinct contributions to khipu description, typology, and decipherment.

En la subcuenca de Magdalena en el estado de Jalisco, los pueblos asentados en las inmediaciones del lago aprovecharon los recursos disponibles para la producción artesanal de bienes útiles y suntuarios. La presencia del Volcán de Tequila, el Lago de Magdalena y el sistema Lerma-Chapala-Santiago, facilitaron el acceso a recursos y la movilidad de productos para su distribución. En el centro del cuerpo acuífero fósil se eleva Atitlán, isla que resguarda evidencia de actividades de producción que se relacionaron con el aprovechamiento de recursos minerales y acuáticos por lo menos a partir del año 450 dC y hasta el 1500 dC. Dentro de las evidencias estudiadas sistemáticamente a nivel de superficie, es de nuestro interés una acumulación de objetos de obsidiana que se extiende en un área de 56.400 m2. El análisis espacial de distribución, junto con los de morfología, desgaste y microscopía aplicada a la identificación de huellas de uso, nos permiten explicar que se trató de un espacio de producción especializado de instrumentos de obsidiana mediante la técnica de talla, los cuales fueron empleados para el aprovechamiento de recursos perecederos.

En contestación a la nota de Bischof (1991) refutando nuevamente la aseveración de Bonavia (1990), sobre la falsedad de la pintura occidental de felino de Cerro Sechín, el autor se reafirma en su posición presentando la argumentación que considera pertinente para demonstrar lo que él juzga es el error de Bischof.
