Early Holocene human occupation in the lowlands of South America- Gruta Azul de Cocalinho, Brazil
Although there are signs of human occupation in the Americas older than 20.000 years, most of the evidence dated to be older than 10.000 years are based on signs of human presence, while human remains from the Early Holocene are relatively rare. In Gruta Azul, in the Cocalinho karst (central Brazil), where human remains were discovered, U-series disequilibrium methods were used for estimating local environmental changes and bone dating, along wit…
Late Quaternary Variations in the South American Monsoon System as Inferred by Speleothems—New Perspectives Using the Sisal Database
Here we present an overview of speleothem δ18O records from South America, most of which are available in the Speleothem Isotopes Synthesis and Analysis (SISAL_v1) database. South American tropical and subtropical speleothem δ18O time series are primarily interpreted to reflect changes in precipitation amount, the amount effect, and consequently history of convection intensity variability of convergence zones such as the Intertropical Convergence…
Cranial and endocranial diversity in extant and fossil atelids (Platyrrhini
OBJECTIVES: Platyrrhines constitute a diverse clade, with the modern Atelidae exhibiting the most variation in cranial and endocast morphology. The processes responsible for this diversification are not well understood. Here, we present a geometric morphometric study describing variation in cranial and endocranial shape of 14 species of Alouatta, Ateles, Brachyteles, and Lagothrix and two extinct taxa, Cartelles and Caipora. METHODS: We examined …
Insights into Holocene megafauna survival and extinction in southeastern Brazil from new AMS 14 C dates
The extinction of late Quaternary megafauna in South America has been extensively debated in past decades. The majority of the hypotheses explaining this phenomenon argue that the extinction was the result of human activities, environmental changes, or even synergism between the two. Although still limited, a good chronological framework is imperative to discuss the plausibility of the available hypotheses. Here we present six new direct AMS 14 C…
Paleoclimate Changes during the last 100,000 yr from a Record in the Brazilian Atlantic Rainforest region and Interhemispheric Comparison
A long terrestrial record, Colônia CO-3, from the Atlantic rainforest region in Brazil (23°52′S, 46°42′20 ʺW, 900 m a.s.l.) registrates variations in the forest expansion during the last 100,000 yr. The 780-cm depth core was analyzed at 2-cm intervals and arboreal pollen frequencies were compared to nearby speleothem stable isotope records and neighboring marine records from the tropical Atlantic. To evaluate regional versus global climate forcin…
