This is an abstract from the "Global Perspectives on Climate-Human Population Dynamics During the Late Holocene" session, at the 84th annual meeting of the Society for American Archaeology. Climate change has been linked to the reorganisation of past societies in different parts of the globe. However, until recently, the lack of archaeological and palaeoclimate data for the Amazon had prevented an evaluation of the relationship between climate change and cultural change in the largest...

This is an abstract from the "SAA 2019: General Sessions" session, at the 84th annual meeting of the Society for American Archaeology. In recent years, there has been a resurgence in interest of co-residence among hunter-gatherers, chiefly in relation to how groups solve collective action problems. The southern Florida interior can greatly contribute to these ongoing discussions with many multi-mound complexes exhibiting periods of monument construction and varying degrees of co-residence...

Found in 1968, the archaeological site of Anzick (24PA506), Montana, contains the only known Clovis burial. Here, the partial remains of a male infant (Anzick-1) were found in association with a Clovis assemblage of over 100 lithic and faunal bone artifacts—all red-stained with ochre. The incomplete, unstained cranium of a separate individual (Anzick-2), dating to ~8,600 radiocarbon years before present (BP), was also recovered. Previous chronometric work has shown an age difference between the...

This is an abstract from the "Geological and Technological Contributions to the Interpretation of Radiogenic Isotope Data" session, at the 89th annual meeting of the Society for American Archaeology. LIA of tin metal must consider the U-Th-Pb characteristics of cassiterite ore. The initial Pb content of cassiterite is <1 ppm and Th is <0.005 ppm. However, it contains as much as 50 ppm U. Therefore, 206 Pb and 207 Pb accumulate over time, potentially allowing the definition of an isochron....

This is an abstract from the "Recent Advances and Debates in the Pleistocene Archaeology of Africa" session, at the 84th annual meeting of the Society for American Archaeology. Advances in understanding the Pleistocene archaeology of Africa depend on well-dated models of human behavioral change. Portions of southern Africa with limestone caves and eastern Africa with volcanic tephra have datable materials (uranium and argon, respectively) beyond the limit of the radiocarbon clock (50ka)....

This is an abstract from the "SAA 2023: Individual Abstracts" session, at the 88th annual meeting of the Society for American Archaeology. Ventana Cave, AZ, and Murray Springs, AZ, have long been candidates for sites demonstrating spatial and temporal overlap between Paleoindians and extinct Pleistocene horses. However, this hypothesis has never before been tested using direct radiocarbon dating, rendering previous speculation ambiguous. AMS radiocarbon dates on horse bone from human...

This is an abstract from the "SAA 2024: Individual Abstracts" session, at the 89th annual meeting of the Society for American Archaeology. For ancestral Caddos living in the Ouachita Mountains of west-central Arkansas, the two centuries between AD 1450 and 1650 saw both continuity and change. An extended period of drought in the 1450s and contact with outsiders beginning with the Spanish in 1541 would have stressed local farming communities. Responses may have included increasing interactions...

The Late Holocene archaeological record of central western Argentina shows a mosaic of human strategies, ranging from farmers to hunter-gatherers. This presentation evaluates if differences in subsistence practices among groups in a similar biophysical environmental generated different demographic and socio ecological responses to climatic change over the last 3000 years. We use radiocarbon dates as a proxy for human population size and growth rates and 13C and 15N stable isotopes on human bone...

This is an abstract from the "SAA 2024: Individual Abstracts" session, at the 89th annual meeting of the Society for American Archaeology. In 2022, the Curaçao Cultural Landscape Project (CCLP) initiated a long-term field investigation on the ecological legacy of Indigenous and European colonial occupation of Curaçao, in the southern Caribbean. Excavation at a recently identified rockshelter site along the inland bay of Rif St. Marie (RSMA) identified significant archaeological deposits...

The Old River Bed delta is a premier open-air Paleoindian locality in the eastern Great Basin. Its chief distinction is scale—some 2,000 square kilometers-plus of nearly continuous and single-component archaeological material on what would have been the largest basin wetland in the region. But the record is largely surficial. In this poster, we detail a series of sites that have yielded temporal data from buried cultural contexts. The sites help clarify the broader associations of artifact types...

Sources of carbon in wetlands and calcareous areas represent unique challenges for interpreting the archaeological radiocarbon record. Atmospheric carbon dioxide is assumed to be the only carbon source for photosynthesis. However, dating modern and historic reference fish and modern reference wild rice indicates the presence of ancient carbon in bones and plant material. Dating four historic reference fish obtained from the Mississippi River in 1939 in southeastern Minnesota yielded four...

This is an abstract from the "SAA 2019: General Sessions" session, at the 84th annual meeting of the Society for American Archaeology. Unlike charcoal, charred food residue has an obvious advantage of fundamental association with use of the pottery and hence, human activity. Food is annual or short-lived. Usually animals hunted for food live only a few to perhaps a few tens of years. Therefore, good dates on food residue from ceramics or pottery should tighten ceramic chronologies and provide...

This is an abstract from the "SAA 2023: Individual Abstracts" session, at the 88th annual meeting of the Society for American Archaeology. Gordon Willey’s pioneering work in the Upper Belize River Valley presented some of the first perspectives on household and community archaeology in the Maya Lowlands. Beginning with that work, scholars came to identify Postclassic occupation at sites along the Belize River, primarily at Barton Ramie and later at Baking Pot. However, the Barton Ramie...

Working with Yanyuwa elders, we collected seven rock painting samples for radiocarbon dating from Kamadarringabaya rock shelter on Vanderlin Island in the southwest Gulf of Carpentaria (Northern Territory). Hand motifs – prints and stencils – dominate the site, covering the shelter walls and roof, and are said by Yanyuwa to be the hands of the Namurlajanyugku spirit beings. In control experiments, negligible levels of humic acid contamination were shown to be present in the unpainted rock;...

This is an abstract from the "SAA 2019: General Sessions" session, at the 84th annual meeting of the Society for American Archaeology. Deptford has been construed as a phase with a time-space-content connotation that incorporates aspects of pottery and adaptation. Recently, we examined regional settlement by considering Deptford phase site distributions and radiometric dates. In this study, we take our analysis a step further by constructing ceramic seriations for sub-regions in which...

This is an abstract from the "Northeast Asian Prehistoric Hunter-Gather Lifeways: Multidisciplinary, Individual Life History Approach" session, at the 88th annual meeting of the Society for American Archaeology. Prehistoric hunter-gatherer cemeteries are usually analyzed as one chronologically flat block of data representing certain groups of people. While justified by small sample sizes or dating problems, such an approach is obviously ahistorical in that it denies these cemeteries and...

This is an abstract from the "SAA 2023: Individual Abstracts" session, at the 88th annual meeting of the Society for American Archaeology. The ice margin chronology for North America provides archaeologists with discrete spatial units, much like stratigraphic units of an excavation grid, that aid in interpreting the archaeological record of colonizing populations. Treating deglaciation as an opening for a subsequent colonization event, ice recession helps contextualize Paleoindian population...
