Dating Techniques: Radiometric (Other Keyword)
51-75 (130 Records)
This is an abstract from the "SAA 2024: Individual Abstracts" session, at the 89th annual meeting of the Society for American Archaeology. Although archaeologists commonly situate the value of our field in its capacity to identify broad-scale patterning in human societies over the long term, critiques of the essentialism and linearity of social evolution led many to abandon this goal in favor of shorter-term, local histories. Drawing from calls for a “process archaeology” that recognizes...
Fremont Maize Cultivation and Latest Holocene Climate Variability in the Cub Creek Archaeological District, Dinosaur National Monument (2018)
The Cub Creek Archaeological District in northern Utah’s Dinosaur National Monument was an early center of Fremont maize cultivation and village settlement AD 450-850. Cub Creek lies near the northern limit of maize cultivation in western North America in the foothills of the Uinta Mountain Range. We couple a Bayesian analysis of radiocarbon-dated pithouses and roasting features with a 2,115-year tree-ring reconstruction of August-July precipitation to explore relationships between Fremont...
From Micro-histories to Macro-trends: Constructing Time and Temporality in the Lower Illinois Valley (2024)
This is an abstract from the "The Village, the Region, and Beyond: Stuart Struever (1931–2022) and the Lower Illinois River Valley Research Program" session, at the 89th annual meeting of the Society for American Archaeology. One of Stuart Struever’s primary contributions to the archaeology of the Lower Illinois Valley was his work outlining a regional culture-history that sought to organize and lend substantive temporality to critical trends and transformations in human social processes. The...
Habitat-Specific Marine Reservoir Corrections along the Central California Coast: The Effects of Differential Upwelling (2019)
This is an abstract from the "SAA 2019: General Sessions" session, at the 84th annual meeting of the Society for American Archaeology. A confluence of natural factors has created three different ecological habitats for marine shellfish with potentially unique marine reservoir offsets along the central California coast. Deep-water trenches adjacent to the rocky points (e.g., Arguello, Conception, Sal), create localized upwelling environments. Reported offsets range from 400-1000 years for...
High Resolution Chronology of the Human Occupation South of Choapa Basin (31°34’ -32° S), Chile (2018)
The area south of Choapa basin in Chile has long been subjected to archaeological research through scientific as well as cultural research management projects. Surveys, excavations, and sampling over these roughly 5000 km2 area has yielded over 370 radiocarbon dates plus over 120 thermoluminiscence dates (almost 0,1 dates/km2). Dates range from 30000 cal BP to modern, but the human occupation is constrained in the last 13,000 years. Such chronometric resolution allows discussing the intensity of...
High-Precision AMS Radiocarbon Chronologies Demonstrate Short-Lived Agricultural Village Occupations on the Northern Colorado Plateau (2023)
This is an abstract from the "The Socioecological Dynamics of Holocene Foragers and Farmers" session, at the 88th annual meeting of the Society for American Archaeology. The Fremont archaeological complex provides an important window into the socioecological dynamics underwriting the formation of settled pithouse communities in the western North America drylands. We developed high-precision AMS radiocarbon chronologies based on short-lived annuals for four Fremont sites (Cub Creek, Caldwell...

Manzanilla from 2000 to 2019, was constructed combining archaeomagnetic dates, a Bayesian radiocarbon model, and detailed information about sample type and archaeological context. The Bayesian model, calibrated using...
Huff Village Revisited: A New Radiocarbon Chronology for a Pivotal Time (2019)
This is an abstract from the "SAA 2019: General Sessions" session, at the 84th annual meeting of the Society for American Archaeology. The large, heavily-fortified Huff village site in North Dakota is a quintessential Late Prehistoric plains village within the Middle Missouri region of the Northern Plains. Since the 1940s, attempts to establish Huff’s occupational history and absolute placement in time achieved only coarse-grained or inconclusive results, suggesting village occupations...
Human Occupation of the Central Balkans during the Last Glacial Maximum: Recent Results from Serbia (2024)
This is an abstract from the "Interdisciplinary Research into the Late Pleistocene of Europe" session, at the 89th annual meeting of the Society for American Archaeology. The Last Glacial Maximum (LGM), or Marine Isotope Stage 2, produced some of the most extraordinary environmental challenges faced by Homo sapiens during the Pleistocene. Large parts of temperate and subarctic Eurasia were depopulated, as humans retreated to areas with relatively favorable conditions. Although the Balkans...
Hydroclimatic Constraints on Population Growth in Dryland Foraging-Farming Communities (2024)
This is an abstract from the "Global Perspectives on Human Population Dynamics, Innovation, and Ecosystem Change" session, at the 89th annual meeting of the Society for American Archaeology. Developing a unified theory of human population growth requires a multiscalar perspective on the evolution of human social-ecological systems over space and time. This requires iteration between macro-level theory and micro-scale events captured in the archaeological record. This poster begins to develop...
Impacts of Abrupt Climate Change Events on Human Paleodemography in the Great Basin (2021)
This is an abstract from the "People, Climate, and Proxies in Holocene Western North America" session, at the 86th annual meeting of the Society for American Archaeology. A central question of research on prehistoric human-environment interaction concerns the role of abrupt versus gradual climate and environmental changes on human demography. This research requires high resolution, regional-scale paleoenvironmental records that provide researchers with the ability to discern variable spatial...
In Search of Hot (or Cool) Dates with Larry (2019)
This is an abstract from the "The Art and Archaeology of the West: Papers in Honor of Lawrence L. Loendorf" session, at the 84th annual meeting of the Society for American Archaeology. Rowe’s research group at Texas A&M University changed their direction about three decades ago when they undertook to develop a method for dating rock paintings. The method is based on the use of plasma-chemical oxidation to gently, at low temperatures, convert to carbon dioxide the organic material that was...

Is La Tène (Still) Relevant in British Iron Age Chronology? (2021)
This is an abstract from the "Constructing Chronologies II: The Big Picture with Bayes and Beyond" session, at the 86th annual meeting of the Society for American Archaeology. La Tène: a chronology that lives beyond the site, beyond regional and national boundaries; a term that conjures images of swirling ambiguous imagery, fine metalwork and shining pots. In Britain the term describes artifacts of apparently comparative date, in particular brooches. La Tène I brooches have strong affinities...
Iterative Temporal Hygiene and Bayesian Analyses of Radiocarbon Datasets: The Impact of Kernel Density Estimation on Clarifying Temporal Relationships among Woodland Period Phases, Middle Scioto Valley, Ohio (2021)
This is an abstract from the "Bayesian Archaeology" session, at the 86th annual meeting of the Society for American Archaeology. The accumulation of radiocarbon dates for Scioto Valley Woodland period sites has created a palimpsest, which inhibits chronological understanding of cultural change. The project iteratively integrates temporal hygiene and Bayesian analyses of large radiocarbon datasets from multiple sites, in an attempt to clean up problematic features of such datasets and provide...

Ladders, Axes, and Pithouses: Elements of a Seventh Century Pueblo Technological Complex (2024)
This is an abstract from the "SAA 2024: Individual Abstracts" session, at the 89th annual meeting of the Society for American Archaeology. Earliest evidence for the widespread use of two-pole ladders and hafted stone axes in the American Southwest’s Central Pueblo area tree-ring dates to the seventh century. That evidence includes, for ladders, remains of the objects themselves, but especially ladder rests found in pithouse floors and, for axes, stone tool heads and stone-axe-cut beams. These...
Landscapes and Chronology of the Chullpa Phenomenon within the Lauca Basin (18°S) (2024)
This is an abstract from the "Beyond the Ancestors: New Approaches to Andean "Open Sepulchers"" session, at the 89th annual meeting of the Society for American Archaeology. The Carangas region, named after a late prehispanic and early colonial chiefdom in Qollasuyu (south-central Andes), preserves over 600 chullpa mausoleums associated with walled hilltops, administrative centers (tambos), and regional movement routes. Carangas’s chullpas exhibit a great diversity of architecture, as well as...
Life after Urbanism: Investigating Classic Period Cities and Settlements in the Mixteca Alta, Oaxaca (2024)
This is an abstract from the "Checking the Pulse II, Current Research in Oaxaca Part 1" session, at the 89th annual meeting of the Society for American Archaeology. Those of us working in the Mixteca Alta region of Oaxaca have heard the saying that the “Classic period” in the region took place earlier, in the Late Preclassic. While the Classic period (AD 300-800) was a time of urban florescence in the Valley of Oaxaca, Basin of Mexico, Puebla, and the Mixteca Baja regions, investigations into...
A “Little Bang” at the Start of the Little Ice Age? Late Mississippian Mound Center Chronology in the Upper Tombigbee River Drainage (2024)
This is an abstract from the "SAA 2024: Individual Abstracts" session, at the 89th annual meeting of the Society for American Archaeology. The Mississippian presence in the Upper Tombigbee River (UTR) drainage is represented by dispersed communities and single-mound centers with modest-sized occupations. The artifact sequence for the UTR closely mirrors that of the neighboring Moundville polity and the UTR traditionally has been viewed as having occupations that extended throughout the...

First, a brief review of traditional approaches to...
Mauretanian and Roman Settlement Chronology in the Loukkos Valley, Northern Morocco (2024)
This is an abstract from the "SAA 2024: Individual Abstracts" session, at the 89th annual meeting of the Society for American Archaeology. Archaeological understanding of the chronology of pre-Roman and Roman occupation of northern Morocco has typically been determined by datable materials from large urban sites. We expand the scope to include smaller sites in the Loukkos River Valley near present-day Larache to investigate the understudied lives of rural populations in Roman North Africa....
Mind the Gap: Occupation at Angkor Wat and Implications for the decline of Angkor (2019)
This is an abstract from the "Paradigms Shift: New Interpretations in Mainland Southeast Asian Archaeology" session, at the 84th annual meeting of the Society for American Archaeology. The Angkor Empire controlled or influenced much of mainland Southeast Asia from the 9-15th centuries CE. Traditionally, scholars have dated the end of the Angkor Empire to 1431 CE, when the capital was sacked by the kingdom of Ayuddhaya in Siam (Thailand). More recent archaeological work has also demonstrated a...
The Mississippian Fin de Siècle in the Middle Cumberland Region of Tennessee (2018)
Bayesian chronological modeling is used to investigate the chronology for a large-scale human depopulation event during the Mississippi period (A.D. 1000–1700) known as the Vacant Quarter phenomenon. The Middle Cumberland Region (MCR) of Tennessee is within the Vacant Quarter area and six villages from the final phase of Mississippian activity in the MCR have been subjected to radiocarbon dating. Complete radiocarbon datasets from these sites are presented within an interpretative Bayesian...
