Os dados oriundos deste sítio contribuem indiscutivelmente nas discussões e nos conhecimentos sobre os processos de povoamento do continente. Por outro lado, a concentração das atenções sobre ele e sobre os debates provocados ofuscaram numerosas pesquisas nesse local que forneceram uma impressionante quantidade de dados sobre as primeiras ocupações humanas nas mais variadas áreas de conhecimento. No presente artigo, a partir de uma revisão bibliográfica, sintetizamos os resultados dessas pesquisas quanto aos contextos e aos comportamentos dos grupos humanos que ocuparam a região durante o final do Pleistoceno superior e o Holoceno inicial. Mostramos, assim, como a pré-história da Serra da Capivara dialoga com os grandes temas sobre o povoamento do continente americano e traz uma contribuição relevante sobre essas questões, nas escalas macrorregionais e continentais. Palavras-chave: Povoamento. Pré-história. Nordeste do Brasil. Tecnologia lítica. Pleistoceno final. Holoceno inicial.

São apresentados os procedimentos empregados em campo e em laboratório para escavação e análise tipológica de um recipiente cerâmico utilizado como urna funerária, bem como é feita análise das características dessa deposição e dos remanescentes ósseos humanos e a sua inclusão no contexto regional do alto rio Uruguai. Uma data de 14 C de fragmento de carvão recuperado no entorno da deposição funerária revelou idade de 395 ± 40 AP, já adentrando o período colonial, mas sem evidências materiais de contato com os europeus. A análise da estrutura do enterramento contribui com novas informações relacionadas ao comportamento funerário da unidade Guarani, visto que, apesar de ser muito descrita pela literatura, carece de contextos documentados na perspectiva arqueológica. Palavras-chave: Alto rio Uruguai. Deposição funerária. Unidade arqueológica Guarani. Abstract: This work presents the results from excavating a funerary arrangement related to the Guarani archaeological unit found in sector 2 of the ACH-LP-07 multicomponent site on the right bank of the Uruguay River in Águas de Chapecó, Santa Catarina. The procedures used in the field and laboratory to excavate and conduct typological analysis of a ceramic vessel used as a funeral urn and to describe this arrangement, the human skeletal remains, and their inclusion within the regional context of the upper Uruguay River are presented for future archaeological interpretation. Carbon 14 dating of a charcoal fragment recovered from the area surrounding the funerary site revealed an age of 395 ± 40 BP, at the beginning of the colonial period, but no material evidence of contact with Europeans was found. Analysis of the burial structure contributes new information on the funerary behavior of the Guarani unit, because even though it has been thoroughly described in the literature, contexts documented from an archaeological perspective are lacking.

It is characterized by industries based on a techno-functional complementarity between tools made from unifacially shaped blanks and retouched flakes. The unifacially shaped artefacts, designated by different names in the literature (for example, limaces, plano-convex tools, unifaces), are historically the most emblematic remains of this technocomplex. Techno-functional analyses of these artefacts demonstrate that they did not correspond to a single tool, but rather to a blank for different simultaneous or successive tools. Many indicators also suggest that these blanks had a long useful live and passed through different technical phases. We present here a study of the chaînes opératoires related to the reconfiguration of the unifacially shaped artefacts of the Itaparica technocomplex during their use-life. To do so, we use the collection recovered during the excavation of the GO-JA-01 rockshelter, in Serranópolis (Goiás state), central Brazil. This important corpus of 377 pieces allows for a good perception of their technical variability. It comes from layers dated between 12,500 and 10,000 calibrated years BP.
Different stages of modification of the unifacially shaped artefacts can be observed. Resharpening is limited to restoring the functionality of an active part. It affects the sides as well as both extremities of the blank. It is common, also, to find these artefacts as fragments, due to transversal fractures. It is not always easy to determine if the fragments are the result of an accident during the use of the artefact or of a deliberate act of reconfiguration. Nonetheless, in various instances, cases of removal scars posterior to the fracture demonstrate that fragmentation was taken into account in the reconfiguration schemes of the unifacially shaped artefacts.
Strictly speaking, reconfigurations concern more important modifications than resharpening, affecting the artefact’s volume and not only its periphery. They correspond to new steps of shaping, either partial or complete. Reconfigurations can be seen at the GO-JA-01 site thanks to detailed analyses to the diacritical schemes of production and by visible differences in artefact surfaces (e.g., double patinas). These modifications can follow one another until the blank is exhausted. In such cases, the artefact no longer possesses operational transformative parts.
By studying the indicators of modification throughout the use-life of the unifacially shaped artefacts from GO-JA-01, one can define two different reconfiguration schemes. In the predominant one, modifications touch mainly the distal and proximal ends, thus reducing the artefacts length. In a secondary scheme, on the contrary, width decreases due to reconfigurations in the sides. Those two schemes can also be found in the collection of artefacts from Lapa do Boquete site (Minas Gerais state).
Reconfigurations can have a significant impact on blank volume and form, but they cannot explain all the variability of these artefacts. It appears that there exists a consistency in the structure of the blanks over time and this calls for the existence of a diversity of intentions from the start of the production of the unifacially shaped artefacts of the Itaparica technocomplex.

In South America, it is well documented in Argentina, in contexts dating back to early Holocene. In Brazil, it was unknown until 2006, when it was found in three archaeological sites (ACH-LP-01, ACH-LP-03, ALP-AA-03) in the Foz do Chapecó area, upper Uruguay River, South Brazil, in layers from early Holocene. It was associated there with a great variety of other production systems: bifacial shaping of projectile points and large tools, unipolar debitage of large flakes, bipolar debitage of tiny flakes. Silicified sandstone, chalcedony and hyaline quartz are the main used raw materials. To this day, only the products of this debitage, the blades, had been discovered. Cores were lacking, which prevented a complete understanding of the flaking process. Due to the resumption of research in the region from 2013, it was possible to find those cores during surveys in the two following archaeological sites: ACH-LP-07 and RS-URG-01, located on both sides of the Uruguay river, near the mouth of the Chapecó river. We describe in this article five of these cores (4 from ACH-LP-07 and 1 from RS-URG-01). Their analyses demonstrate that this blade debitage complies with only one concept. The core volumetric structure that is the result of this concept displays the following features: 1) Cores have two surfaces: a flat back and a convex but relatively flattened flaking surface, so that they have a general “D” shaped transversal section. At one end, a small surface acts as striking platform during the production of the blades; 2) Debitage begins with a initialization phase of the core during which the striking platform is produced by a large removal. According to the natural properties of the initial volume, the back of the core is obtained either during the selection of the blank, and then it is left in his natural state, or by a preparation by one or more large transversal removals. When present, the scars of the initialization phase of the flaking surface indicate the use of a centripetal method. This preparation is made possible by the acute angle of the peripheral ridge formed by the intersection of the back and the flaking surface ; 3) Blades are always produced by a unidirectional parallel method. Production variability is mainly related to the flaking technique: both internal percussion by stone and marginal percussion by organic percussor were used to get the blades. Technical information provided by the cores are complementary and in accordance with those from the previous analyses of the blades from the same area. With these two studies it was possible to reach a relatively exhaustive understanding of this production system in the upper Uruguay River during early Holocene, the only well documented blade debitage in Brazil known until now. Future research will explore the interactions between this production and the other debitage and shaping methods inside this early Holocene technological system. To do this, we will develop a comprehensive study of all lithic artefacts from the archaeological layers in which blade production was identified. In a wider scale, a comparative approach with Argentinian and Uruguayan prehistoric blade productions will allow to better understand the development of the blade phenomenon in the southern cone of South America.

Propomos aqui outra abordagem da pré-história da área, com uma apresentação das características e das mudanças dos sistemas técnicos ao longo da sequência de ocupação, do Pleistoceno final ao Holoceno recente.

A dúzia de sítios arqueológicos considerados nesse estudo abrange todo o período de ocupação da Serra da Capivara durante a pré-história. Podemos, assim, propor um novo olhar sobre a sequência técnica regional, que se divide em quatro grandes momentos. Abstract: The great archaeological potential of the Serra da Capivara region, State of Piauí, Brazil, has already been demonstrated in many publications, mainly about the rock art in rockshelters (the " tocas ") and the Pleistocene settlements, among the earliest ones in America. We propose here another approach to prehistory of this area, introducing the characteristics of the technical systems and their changes along the archaeological sequence, from latest Pleistocene to late Holocene. We based on the direct analyses of lithic remains from three sites (Toca do João Leite, Toca da Ema do Brás, Toca do Baixão da Ana Maria) and on data available in publications on other sites. The dozen archaeological sites taken into account in this study cover all of the prehistoric settlement period in the Serra da Capivara region. Hence, we propose new insight on the regional technical sequence, which can be divided in four main periods.

Nela foram localizados sítios de caçadores-coletores, referentes ao passado mais antigo da região, e de grupos ceramistas relacionados às unidades arqueológicas Tupiguarani e Taquara-Itararé. Este artigo apresenta os primeiros resultados das pesquisas realizadas no sítio ACH-LP-07 situado próximo à foz do rio Chapecó, à margem direita do rio Uruguai, no oeste de Santa Catarina. O rio apresentou várias ocupações de populações de caçadores-coletores no início do Holoceno, caracterizadas por uma variabilidade nas produções de pedra lascada, onde se destaca a produção de lâminas por uma debitagem específica. No último milênio, o local também foi povoado por grupos ceramistas Guarani. O sítio tem trazido diferentes contribuições a respeito dessas antigas sociedades, especialmente as modalidades de ocupação e de sucessão dos grupos humanos no alto rio Uruguai.

Complex VI3 corresponds to a lacustrine phase during which the site was regularly covered by water and sedimentary deposits. Nine archeological layers are present, dating to around 70 ka. The assemblage from layer VI3a has revealed the co-existence of at least two chaînes opératoires of reduction: (a) recurrent Levallois focused on the production of points associated with quadrangular and overshot flakes; (b) recurrent Levallois focused on the production of points, laminar and quadrangular flakes. Other data, such as that related to the remains of hunted fauna recovered in this layer, complement these results and also contribute to a better understanding of the status of the site of Umm el Tlel and, more generally, its role within a broader territory that we can now better define. In a diachronic perspective, occupation dynamics can also be addressed by the study of all of the archeological layers in complex VI3. Based on results of analyses completed, these layers are remarkably uniform throughout this specific geological context, from all perspectives (reduction techniques, hunting strategies and faunal treatment, sites functions, etc.). Thus, the human behaviors revealed by the material recovered from complex VI3, although relatively complex, seem to have been quite stable. This stability, at present difficult to quantify in terms of duration, suggests a degree of rigidity in Mousterian territories where, despite intermittent occupations, human groups regularly returned to the same places to carry out the same range of activities.

Foi denominado tradição Itaparica e definido a partir de uma base tipológica pela presença, nos conjuntos líticos, de peças façonnées unifacialmente, geralmente chamadas lesmas. Tal definição, baseada somente sobre um único tipo de artefatos, não descrito em detalhe, conduziu a uma divergência dos pontos de vista e a críticas em relação a esse conjunto cultural a tal ponto que sua própria existência é atualmente questionada. No entanto, examinando os dados bibliográficos disponíveis, se pode constatar a existência de uma concentração notável de sítios com peças façonnées unifacialmente nessa região, entre 12.000 e 7.000 BP.

The lithic material from the site consists mainly of a very rich stratigraphic layer, level 1B, dated between the Pleistocene-Holocene transition and the early Holocene. The set of artifacts comes from an original production and contains a significant proportion of standardized instruments. Two groups of artifacts stand out, namely, elongated instruments with a side edge opposite to a back and pieces unifacially shaped with ground distal part. Level 1B-2 appears to have significant technical relationships with level 1B. In the other levels with lithic material, 1A and 2, few traces were found, which do not allow fine characterization of material from these levels. The material from level 2 demonstrates occupation of the site since the late Pleistocene.
