As part of the research program “Archaeology of rock art in Mato Grosso: the Chapada dos Guimarães National Park (Cuiabá, Brazil)” placed under the coordination of Patrick Paillet and Veronica Wesolowski, an integrated and interdisciplinary approach to the territory still largely unpublished rock art of the Chapada dos Guimarães, has been undertaken since 2020 by combining strictly archaeological research (surveys, excavations and prospecting-inventories), rock art studies (analysis and graphic, photographic and photogrammetric recording of representations) and geological analyzes and, to define and characterize the structure of its ornamented landscapes. Our program is an extension of other projects carried out from 1983 to 2013 under the direction of Agueda Vilhena-Vialou, Denis Vialou and Levy Figuti in the region of the Cidade de Pedra near Rondonópolis and at Santa Elina in the Serra das Araras (Jangada). The region of the Chapada dos Guimarães National Park (PNCG) was the subject of exploration and partial studies between 2017 and 2019 under the direction of Caroline Bachelet within the framework of the program “Prehistory and Paleoenvironments in the Pantanal region (Mato Grosso, Brazil)”. The pursuit of archaeological research in the PNCG contributes to better defining the chronology and the dynamics of occupations at local and regional scales, to characterizing chrono-culturally the settlements and their variability in the region, extending from the Rio Vermelho in the south to the Rio Cuiabá in the north, and to understand the processes of settlement and/or mobility of past populations along the firm lands and especially the hydrographic systems that border the floodplains of the Pantanal and which constitute the main routes of population movement.

The study of early lithic assemblages from South America's Southern Cone used to be strongly focused on projectile points, including the famed fishtail type, often using a typological approach. The last three decades have seen a growing diversification of theoretical and methodological approaches to lithic studies, as well as new analytical techniques, used to study issues including lithic production systems, technical variability, tool manufacturing and management, raw material economy and circulation, among others. Recent studies on lithic industries are exemplified by discussing Southernmost Patagonia's first human occupations, dated ∼13,000 cal BP, and Middle Holocene early marine explorations, dated ∼8000–7000 cal BP. An overview and comparison of Southernmost Patagonia's early hunter-gatherer lithic technologies is made.

Between ≈13,000 and 7000 BP, the territory of southern Brazil was occupied in a stable and diverse manner, with the main anthropic trace being in lithic material. Archaeological research has provided more consistent evidence of occupation in different environments and associated with different stratigraphic formation processes since the Late Pleistocene. Therefore, this paper proposes to analyse the history of the earliest evidence of pre-colonial occupation in southern Brazil from a geoarchaeological point of view, focusing on stratigraphic and chronological data and the process of formation of archaeological layers. Thirty-three stratigraphic sections were analysed from 31 archaeological sites distributed along the Paraná, Uruguay and Atlantic basins. Evidence of archaeological levels was found in different geomorphological contexts: plateau, slopes, valley bottom, alluvial plains and rockshelters. The results indicate that the oldest archaeological levels in the region were formed in the Late Pleistocene, associated with periods of fluvial incision that signal important changes in the southern river systems, characterized by the formation of alluvial and colluvial-alluvial terraces in the valley bottoms. This is followed in the Lower Holocene by widespread colluvial processes in the incised valleys, alluvium in the middle river courses and anthropogenic deposits in the rockshelters that formed the main ancient levels. In the early Middle Holocene, sedimentary deposits containing archaeological material decrease significantly, marking regional changes in lithic industries. The data indicate that there appears to be a threshold between deposition and archaeology in the Early Holocene, characterized by high stratigraphic resolution, where stratigraphic sequences show greater thickness and density of archaeological levels. Finally, the diversity of inter-regional lithic assemblages is clearly highlighted, marked by the predominance of industries on pebbles and blocks, the debitage of flakes and blades as a support for various tools in the interior basins and the shaping of small projectile points on the Atlantic slope.

The variety of South American lithic industries in the Early Holocene indicates that the settlement processes were characterized by cultural diversification and adaptive flexibility. In the present article, we will analyze the bifacial lithic industries of southern Brazil that include projectile points in their repertoire of instruments, through a comparative study between the results of research in the hydrographic regions of Uruguay River and Lake Guaíba. Our objective is to problematize issues about the construction of cultural territories in the process of initial settlement of the South American Cone through the analysis of technical systems.

Three decades after the end of excavations at Pedra Furada, Northeastern Brazil, the site has been almost excluded from the debate about the first phase of human expansion in the Americas. Since the radiocarbon chronology spanning a period from 7 to 60 ky ago is unquestioned, most scepticism focuses on the anthropic nature of the artifacts and structures from the Pleistocene layers. The main objections concern the flaked tools on endogenous raw material, possibly resulting from rock spalling or being the involuntary product of monkeys’ battering activities. Fireplaces and other structures have been also questioned on the basis of the occurrence of bush fires and possible waterflow. In this paper, the entire evidence from the Pleistocene units is updated and presented in English, in a dynamic display aiming to facilitate the inspection by the reader, including hundreds of unpublished photographs. The main objections questioning the validity of this important archaeological sequence are discussed in the context of its regional setting and of the main pre-LGM sites in the Americas.

The most abundant evidence of Pampean Pleistocene human presence are modified bones, as lithic procurement sites located farther than 300 km away. Therefore, we focused on the study of bone modifications, in particular cut and percussion marks. We studied Pampean paleontological collections of Argentine and European museums as an alternative resource of previously unnoticed human modification evidences. We compared marks characteristics with those of archaeological collections from diverse climatic and cultural adaptations, from middle Pleistocene sites (Vallonet, Atapuerca, Lazaret, Arago and Terra Amata) to terminal Pleistocene ones (Abri Pataud, Isturiz and La Vache). Marks typologies were defined, leading to the identification of a particular cutmark that we named double parallel considered as highly diagnostic of anthropic use of lithic artifacts. We also propose that hafted artifacts were used on carcass processing. Perimortem bone modifications are classified in relation with mark morphology (e.g., percussion striae), inferred gesture or action (e.g., breakage of diaphysis), and inferred objective of that action (e.g., marrow extraction). The megafauna specimens analyzed from the historical collections (d’Angelis-Vilardebó, 1847, Muñiz-Dupotet, 1842 and Breton-Bonnement, 1881) present modifications compatible with dismemberment, defleshing, tongue and masseter extraction, and utilization as anvils. The lack of contextual data (location, stratigraphy) and the loss due to museum selection/collecting of accompanying material prevent paleoenvironmental and paleoecological inferences. Regional geology indicates that most of the historical collections were exhumed in riverbank cuts with ages between 70 and 13 ky BP. Preliminary direct dating presents evidence of a Pampean human occupation, at least, since OIS 2.

Regions with low population density, which are geographically marginal with respect to the most frequently occupied areas, are theoretically more prone to discontinuities in human occupation. This is the case in Central-West Patagonia (Chile, South America), where the discontinuities have had different characteristics and extents, some even lasting millennia. This work proposes that, given the prolonged and repeated periods of abandonment of some areas in Central-West Patagonia, its exploration is not to be considered a unique, one-time process; rather, it occurred more than once throughout its history. Because ascertaining each exploration is complex, this process can be investigated by focusing on spaces that represent the incorporation of new areas as human groups were enlarging their ranges of action. With this objective, updated archaeological data are presented in two different types of environments of the region: forests and highlands. These environments were marginal sectors that were not utilized as frequently or intensely as the valleys and where the archaeological record would be expected to preserve the actions associated with exploration contexts. The preliminary nature of data precludes defining exploratory contexts, but it is distinct in orienting its search in time and space.

This paper reviews more than 20 years of research about the Late Pleistocene and Early Holocene occupations of the Uruguayan plains. The aim of this synthesis is to provide an overview of the available information related to early human peopling of Uruguay. Here, we focus on the main issues discussed over the last two decades: early sites characterization and chronology, human response to climate change, cultural diversity, occupations patterns, mobility and technology. The systematic and continuous efforts made have provided new data and new perspectives regarding the earliest human occupations of the region. We have defined an archaeological complex landscape and ongoing research strategy is based on the three main types of site that compose it: residential camps, cave and rock shelters, and raw material sources. This has allowed us to expand and improve our understanding of the record. The new research and data provided by these sites have led us to propose a settlement model for the region and the period. A cultural diversity has been evidenced through in-depth studies of stratified archaeological sites, cultural sequence, a solid chronological database and lithic technology. Finally, we advance in the characterization of objects of social prestige among hunter-gatherers who occupied the plains during the end of the Pleistocene in Southeastern South America.

The discovery of Pleistocene human presence at Chiquihuite Cave (state of Zacatecas, Mexico) dating to, or even before, the Last Glacial Maximum (LGM, over 18,000 years ago), prompted the search for another cave site in the same region, where the implications of Chiquihuite could be tested and corroborated in a second context. In January 2020, we started work at Sima de las Golondrinas (“Chasm of Swallows”), a cavern in the Zuloaga mountains. Excavation unit X-20 focused on an older profile left behind by unknown early-20th-century explorers. Previous radiocarbon dating of three charcoal-rich deposits had indicated the stratigraphy contained deposits ranging in age from the Terminal LGM to the Middle Holocene. The short-timed excavation revealed the stratigraphic sequence had been slowly deposited in an aquatic environment, when the cave was partly inundated for thousands of years, until the Holocene. Preliminary palynological studies confirmed the presence of water and nearby lakes, matching the paleoenvironmental reconstructions from Chiquihuite, 100 km away. Excavation X-20 yielded no lithic tools or stone raw materials, but an abundance of zoo-archaeological materials, yet without the presence of traditional megafauna. Some specimens present human modifications in the form of butchery-related cut marks, but also engravings possibly related to early symbolic behaviors. Here, we present a selection of eight bones of elevated archaeological importance. One of them is an ischium bone belonging to a young Homo sp. individual, dating to the Early Holocene. The other seven are modified bones coming from layers dating between the Terminal LGM and Younger Dryas. They belonged to white-tailed deer (Odocoileus virginianus), mountain bighorn sheep (Ovis canadensis), and American pronghorn (Antilocapra americana). The assemblage includes four human-modified animal phalanges, with symbolic expression substrates. Two of them were found in levels older than 16,000 years, and may well represent some of the oldest forms of art in the Americas.

Here are described two sleds, presumed to date to the time of the Clovis (Llano) archaeological culture or approximately 13,500-12,500 years ago, that were discovered at saline springs in New York state and Kentucky state. For what purpose these sleds may have been intended and why they were abandoned are addressed by referring to eastern Eurasian ethnography. The proboscidean components used in their construction may have restricted use of these sleds to ritual activities.
