Around 400 BCE, inhabitants of the Southern Andes took up a sedentary lifestyle that included the practice of agriculture. Settlements were generally solitary or clustered structures with walled agricultural fields and animal corrals, and the first small villages appeared in some regions. Surprisingly, people were also producing and circulating exotic goods: polychrome ceramics, copper and gold ornaments, bronze bracelets and bells. To investigate the apparent contradiction between a lack of social complexity and the broad circulation of elaborated goods, archaeologist Joan Gero co-directed a binational project to excavate the site of Yutopian, an unusually well-preserved Early Formative village in the mountains of Northwest Argentina. In Yutopian, Gero describes how archaeologists from the United States and Argentina worked with local residents to uncover the lifeways of the earliest sedentary people of the region. Gero foregounds many experiential aspects of archaeological fieldwork that are usually omitted in the archaeological literature: the tedious labor and constraints of time and personnel, the emotional landscape, the intimate ethnographic settings and Andean people, the socio-politics, the difficult decisions and, especially, the role that ambiguity plays in determining archaeological meanings. Gero’s unique approach offers a new model for the site report as she masterfully demonstrates how the decisions made in conducting any scientific undertaking play a fundamental role in shaping the knowledge produced in that project.

One person’s lifelong research pursuit is brought to fruition here, in the first major publication on the planning and archaeology of the Inka capital of Cusco. No other book to date has focused so extensively on the oldest existing city in the Americas, the “navel of the world” according to the Inka Empire, a fascinating and complex urban landscape that grew and evolved over 3,000 years of continuous human habitation.

A fundamental component of the study of worked osseous objects is the identification of the raw materials chosen to make them. In archaeological contexts many objects become degraded to the point where identification is very difficult and the way in which these materials decay during burial and upon excavation can vary greatly. Correct identification is crucial to the investigation of objects, their conservation and future curation. Above all, understanding raw material selection aids our understanding of human-animal interaction in the past both on pragmatic and symbolic levels since the choices made by artisans vary by cultural tradition as well as availability. The 20 papers presented here explore a wealth of information pertaining to the use of osseous materials over the long period of human craftsmanship and tool manufacture by exploring several key themes: · Raw material selection and curation within tool types · Social aspects of raw material selection · New methods of materials identification It is demonstrated that the issue of raw material identification has numerous implications for conservation work, reproduction of objects, the physical characteristics of the tool or ornament, availability of raw materials, the materials chosen for procurement and the cultural reasons that lie behind the choice of raw materials from particular species and skeletal elements to produce planned tool and ornament types. Together, these papers emphasize the need for confident and correct materials identification and demonstrate that functionality is by no means the only, nor necessarily the most important, factor in the selection of osseous raw materials for the fabrication of tools and other cultural objects.
