Uso de fibras vegetais nas práticas funerárias: O sepultamento em artefato entretorcido tipo esteira/rede na cova 13, c. 5.000 AP, Toca do Alto da Serra do Capim, Piauí, Brasil
A utilização de artefatos feitos a partir de fibras de matérias-primas vegetais, por técnicas de trançado ou tecelagem, apresenta ampla distribuição geográfica e temporal no Brasil, apesar dos problemas de preservação dos materiais orgânicos perecíveis. Entre as suas múltiplas utilizações como equipamento doméstico ou de trabalho, destaca-se o uso desses objetos nas práticas funerárias, quer como acompanhamento, quer como recipientes para contenç…

Older Burial Disturbance: Postfunerary Manipulation of Graves and Corpses in Precontact Northeastern Brazil
At times funerary practices do not end with the deposition of the corpses in their final resting place, because occasionally these supposedly definitive burials are disturbed later. When we can confirm that people were mainly responsible for these disturbances, even when other natural taphonomic factors are present, then we have a situation of anthropic postfunerary manipulation of bodies and graves. Some precontact sites in northeastern Brazil h…
The First Fishtail Point Find in Piauí State, Northeastern Brazil: Significance and Hypothesis
Here we report a newly discovered Fishtail, or Fell 1, projectile-point type, from Coronel José Dias, southern Piauí, northeastern Brazil. It is an almost complete bifacial piece on light local silex. In Brazil, Fishtail points have not been previously reported in detail north of the 22° S parallel. Hence, this new evidence importantly establishes human occupation of extreme northeast of South America during the Pleistocene-Holocene transition
Formation Processes of the Late Pleistocene Site Toca da Janela da Barra do Antonião – Piauí (Brazil)
Archaeological research of late Pleistocene sites in northeastern Brazil has rarely analyzed site formation processes from a geoarchaeological perspective. This has contributed to the long-held debate over the reliability of Pleistocene ages and the anthropic origin of stone tools and combustion features. In this work, we combine high-resolution geoarchaeological methods to study the formation processes of the Toca da Janela da Barra do Antonião …
Fetal Bioarchaeology: A Case-study of a Premature Birth from Burial 2 in Toca do Enoque (Middle Holocene, Northeastern Brazil)
Generally, due to their small size and fragility, the discovery of fetuses in archaeological contexts is an uncommon event. From a bioarchaeological perspective, when such contexts are found, their study allows us to explore maternal-fetal stress conditions related to pregnancy or birth. It also allows us to assess the sociocultural aspects behind individual identity and group-affiliation based on funerary practices. In this article, after discus…
An archaeothanatological approach for interpreting a complex funerary deposit: The case study of "Burial 2" at Toca do Enoque (Middle Holocene, Northeastern Brazil)
Applying the Bioarchaeology of Care model to a severely diseased infant from the Middle Holocene, north-eastern Brazil: A step further into research on past health-related caregiving
A potential context of care is suggested in a case study of an anomalous burial from a severely diseased infant of 9 months (±3 months) of age at death, which displayed significant signs of infectious and/or metabolic illnesses on the skeleton. The body also received special mortuary treatment, including associated body reduction processes and display of corporeal relics. The case study corresponds to Individual 9 from Burial 2 at Toca do Enoque,…
Funerary Practices at the Toca do Gongo III Site during the Late Holocene in Serra da Capivara (Piauí, Brazil)
In this article we present the results of archaeological research at the Toca do Gongo III site, a rock-shelter with evidence for Nordeste and Agreste Tradition rock art located in the Serra da Capivara National Park (Piauí, Brazil). This park was declared a World Heritage site by UNESCO in 1991. The bioarchaeological analysis of 12 human burials excavated at the Toca do Gongo III archaeological site reveals evidence for its use as a place of fun…
Finding the unexpected: A critical view on molecular diagnosis of infectious diseases in archaeological samples
New Data on a Pleistocene Archaeological Sequence in South America: Toca do Sítio do Meio, Piauí, Brazil
Sítio do Meio, discovered in the 1990s, showed a sedimentary sequence clearly composed of two sets of deposits separated by a zone of large rockfall from the massive collapse of the shelter's overhang. The bottom set, slightly more than 60 cm thick, was trapped between the bedrock (upon which it rested) and the lower part of the roof fall (reaching more than 1 m in the excavation area), and yielded some charcoal without other archaeological mater…
Genomic evidence for the Pleistocene and recent population history of Native Americans
Genetic history of Native Americans Several theories have been put forth as to the origin and timing of when Native American ancestors entered the Americas. To clarify this controversy, Raghavan et al. examined the genomic variation among ancient and modern individuals from Asia and the Americas. There is no evidence for multiple waves of entry or recurrent gene flow with Asians in northern populations. The earliest migrations occurred no earlier…

International audience
A new late Pleistocene archaeological sequence in South America: The Vale da Pedra Furada (Piauí, Brazil)
The date of the first settlement of the Americas remains a contentious subject. Previous claims for very early occupation at Pedra Furada in Brazil were not universally accepted (see Meltzeret al.1994). New work at the rockshelter of Boqueirão da Pedra Furada and at the nearby open-air site of Vale da Pedra Furada have however produced new evidence for human occupation extending back more than 20 000 years. The argument is supported by a series o…
Chronologie des peintures rupestres du Parc National Serra da Capivara (Brésil)
En 1973, des sites à peintures rupestres ont été découverts dans le sud-est de l’État du Piauí. Dans une région très accidentée, un ensemble de plateaux gréseux surplombe la plaine sur environ 200 km2 selon la direction sud‐ouest / nord‐ouest. C’est l’une des régions les plus pauvres du Brésil, semi-aride, avec une couverture végétale typique, la caatinga, mot indien qui signifie « forêt blanche ». Ces sites, en raison de leur importance archéolo…
Chronology of the Rock Paintings in the Serra da Capivara National Park (Brazil)
In 1973, sites with rock paintings were discovered in the southeastern part of the State of Piauí. In a very uneven terrain, a group of sandy plateaus overlooks a plain covering approximately 200 km2 following a south‐west / north‐west direction. This is one of the poorest regions of Brazil. It is semi-arid, with a typical vegetal cover called “caatinga”, which is the Indian word for “white forest”. Due to their archaeological importance, these s…
Human occupation in South America by 20,000 BC: The Toca da Tira Peia site, Piauí, Brazil
Cross-Dating (Th/U- 14 C) of Calcite Covering Prehistoric Paintings at Serra da Capivara National Park, Piaui, Brazil
The question of when the first humans arrived in the New World has been a bone of contention for several decades. Similarly, the age of rock paintings has been heatedly debated. Settlements in the Serra da Capivara National Park have been dated to between 5 kyr and >50 kyr, which is far older than the Clovis barrier. Moreover, calcite formation on a rock-wall painting in a rockshelter yielded thermoluminescence (TL) and electron paramagnetic reso…
Zuzu” strikes again—Morphological affinities of the early holocene human skeleton from Toca dos Coqueiros, Piaui, Brazil
The Serra da Capivara National Park in northeastern Brazil is one of the richest archaeological regions in South America. Nonetheless, so far only two paleoindian skeletons have been exhumed from the local rockshelters. The oldest one (9870 ± 50 BP; CAL 11060 ± 50), uncovered in Toca dos Coqueiros and known as “Zuzu,” represents a rare opportunity to explore the biological relationships of paleoindian groups living in northeastern Brazil. As prev…
Serra da Capivara National Park, Brazil: Cultural Heritage and Society
The Serra da Capivara National Park was created in 1979 in order to protect the existing archaeological sites (more than 900). During its first ten years federal officials were lax concerning the commitments that had been assumed. The consequence was a devastating environmental impact on the archaeological heritage. Looking for a solution in 1986 FUMDHAM was created to implement the protection of the archaeological heritage and to ensure the cont…
Some Evidence of a Date of First Humans to Arrive in Brazil
Osteobiographic analysis of skeleton I, Sítio Toca dos Coqueiros, Serra da Capivara National Park, Brazil, 11,060 BP: First results
This paper presents an osteobiographic analysis of a single skeleton found in a small rock shelter known as Toca dos Coqueiros, Piauí, Brazil. This find is of interest because of an exceptionally old radiocarbon date associated with it. The date (11,060 BP) was obtained from charcoal associated directly with the skeleton. This is an interesting find because of the rarity of osteobiographic studies of skeletons of such antiquity. Despite the exist…
Nature and age of the deposits in Pedra Furada, Brazil: Reply to Meltzer, Adovasio & Dillehay
The archaeological evidence of the Pedra Furada rock-shelter (northeastern Brazil), showing a long sequence of dated layers from 50,000 years b.p., was questioned in a paper presented by Meltzer, Adovasio & Dillehay, who visited the region at the end of 1993, in volume 68 of ANTIQUITY (1994). This paper presents the reply of the team directly involved in the research programme in this key area of American prehistory
