Archaeological Evidence and the Chronology of K'iche'an Dominance in the Guatemalan Highlands (2019)
DOCUMENT Citation Only Thomas Babcock.

This is an abstract from the "Art, Archaeology, and Science: Investigations in the Guatemala Highlands" session, at the 84th annual meeting of the Society for American Archaeology. The K’iche’an ethnohistoric documents posit movement of Chontal-Nahuan groups into, and conquest of, the central Guatemalan highlands. A list of K’iche’ rulers was used to establish a timeline for occupation of the archaeological sites of Chujuyub, Jakawitz, and Q’umarkaj. Accordingly coinciding with the fall of...


Bayesian 14C Chronology of Tlajinga, Teotihuacan Compounds 17 & 18 (2018)
DOCUMENT Citation Only Gina Buckley. David Carballo. Daniela Hernandez Sariñana. Kenneth Hirth. Douglas J. Kennett.

A high-resolution chronology of two residential compounds (17:S3E1, 18:S3E1) recently excavated in the Tlajinga district of Teotihuacan has been developed using high-precision AMS 14C dating and artifact seriation datasets. The Tlajinga district is located along the southern Street of the Dead and was a possible entrance for migrants and visitors to the densely populated urban center of Teotihuacan during the Classic Period. Ceramic evidence suggests this district was occupied during the height...


Bayesian Models for the Occupational History of Complex Hunter-Gatherer-Fisher Communities in the Interior Pacific Northwest (2019)
DOCUMENT Citation Only Nathan Goodale. Anna Marie Prentiss. Alissa Nauman.

This is an abstract from the "Complex Fisher-Hunter-Gatherers of North America" session, at the 84th annual meeting of the Society for American Archaeology. The interior Pacific Northwest landscape contains a system of waterways that coalesce to form three major drainages with outlets in the Pacific Ocean. Substantial evidence has been provided that complex hunter-gatherer-fisher communities occupied sites in these river drainages during the late Holocene. Some chronological frameworks...


Bayesian Reconstruction of Past Demography (2018)
DOCUMENT Citation Only Michael Price.

I describe a novel, age-structured, Bayesian framework for reconstructing past demography. The framework is quite flexible and can incorporate and synthesize a wide range of data. I demonstrate its use with human burial data, where each observation can include an AMS radiocarbon measurement, an estimate of age-at-death, or both. Conceptually, the framework is useful because it addresses in a statistically principled way two vexing sources of equifinality in archaeological data: (1) the...


Blind Dates and Nervous Anticipation: Adding Temporal Context to Perishable Artifacts in Legacy Collections from eastern Utah (2019)
DOCUMENT Citation Only Tim Riley.

This is an abstract from the "How to Conduct Museum Research and Recent Research Findings in Museum Collections: Posters in Honor of Terry Childs" session, at the 84th annual meeting of the Society for American Archaeology. The Ephraim P. and Dorothy Hickman Pectol Collection, probably the largest single collection of Fremont-associated perishable artifacts, was donated to the Utah State University Eastern Prehistoric Museum in the Spring of 2017. Most of this collection was amassed from...


Bones of the Lucayans: Radiocarbon dating of human remains from the Bahamian Archipelago (2019)
DOCUMENT Citation Only Rick Schulting. Joanna Ostapkowicz. Michael Pateman. William Keegan. Fiona Brock.

This is an abstract from the "Advances in the Archaeology of the Bahama Archipelago" session, at the 84th annual meeting of the Society for American Archaeology. The Bahamas were among the last islands to be settled in the Caribbean, with no known occupation prior to ca. AD 600 and reportedly complete depopulation by ca. AD 1520. The constrained island setting and restricted timescale provides an excellent opportunity to address a range of questions relating to island adaptations, all...


Building a High-Resolution Chronology: A Case from the Maya Archaeological Site of El Palmar, Mexico (2018)
DOCUMENT Citation Only Kenichiro Tsukamoto. Fuyuki Tokanai. Toru Moriya.

This paper aims to refine the Maya chronology during the Classic period (A.D. 250-950) through the development of Bayesian models. In so doing, we combined radiocarbon dates with stratigraphic information, ceramic data, burials, and calendric dates from stone monuments. At the Center for Accelerator Mass Spectrometry of Yamagata University, we ran 78 radiocarbon samples recovered from the Guzmán Group, an outlying group located 1.3km north of El Palmar in southeastern Campeche, Mexico. To...

DOCUMENT Citation Only Anthony Krus. Edward Herrmann. Matthew Pike. G. William Monaghan. Jeremy Wilson.

This is an abstract from the "SAA 2019: General Sessions" session, at the 84th annual meeting of the Society for American Archaeology. Geophysical survey and excavations from 2010–2016 at Lawrenz Gun Club (11CS4), a late pre-Columbian village located in the central Illinois River valley in Illinois, identified 10 mounds, a central plaza, and dozens of structures enclosed within a stout 10 hectare bastioned palisade. Nineteen radiocarbon measurements were taken from single entities of wood...


Chronology of the Human Occupation of the North-western Channels of Patagonia (43°-46° S), Chile (2018)
DOCUMENT Citation Only Omar Reyes. Cesar Méndez. Manuel J. San Román.

We present results of a systematic radiocarbon dating program carried out in the Chonos archipelago, the northernmost part of the channels of western Patagonia. Eighty-six samples obtained from a variety of archaeological sites, including: strata beneath organic soils, open-air shell middens, caves and rock shelters, individual burials and ossuaries, and modern industrial extraction shell middens, were analyzed. The chronological and spatial distribution of dates along with the analyzed...


Climate Change and Culture in Late Pre-Columbian Amazonia (2019)
DOCUMENT Citation Only Jonas Gregorio De Souza.

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...


Co-residence in Hunter-Gatherer Groups: New Insights from the Southern Florida Interior (2019)
DOCUMENT Citation Only Matthew Colvin.

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...


Comparison of Preparative Chemistry Methods for the Radiocarbon Dating of Anzick Site, Montana (2018)
DOCUMENT Citation Only Lorena Becerra-Valdivia. Thibaut Devièse. Thomas W. Stafford Jr.. Michael Waters. Tom Higham.

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...


Construction of Pleistocene Geochronologies in Central Africa: Luminescence Dating in Northern Malawi (2019)
DOCUMENT Citation Only David Wright. Jeong-Heon Choi. Jessica Thompson.

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)....


Contrasting Human Demography Trends between Hunter-Gatherers and Farmers as Response to Climate Change: Central Western Argentina as Study Case (2018)
DOCUMENT Citation Only Adolfo Gil. Gustavo Neme. Ricardo Villalba. Jacob Freeman.

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...


A Critical Review of Radiocarbon Dates Clarifies the Human Settlement of Madagascar (2019)
DOCUMENT Citation Only Sean Hixon. Kristina Douglass. Henry Wright. Brooke Crowley. Laurie Godfrey.

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. The timing and subsequent environmental impacts of the human settlement of Madagascar remain key topics of debate in archaeology. Located approximately 250 miles off the East African coast, Madagascar, the fourth largest island in the world, appears to have been one of the world’s last large landmasses to...


The Dated Paleoindian Archaeology of the Old River Bed Delta (2018)
DOCUMENT Citation Only Daron Duke. D. Craig Young.

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...


Dates Too Old?: Mixed Carbon Reservoirs Integrate Carbon from Freshwater Reservoirs and the Atmosphere (2018)
DOCUMENT Citation Only Linda Scott Cummings. R. A. Varney. Thomas W. Stafford Jr.. Scott Anfinson. Patricia Emerson.

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...


Dating Charred Food Crust: Offsets, Pretreatment, and Organic Compunds (2019)
DOCUMENT Citation Only Linda Scott Cummings. R. A. Varney. Thomas W. Stafford Jr.. Robert J. Speakman.

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...


Dating the Spirit Men: Radiocarbon Dating Saltwater Rock Art of the Yanyuwa People in Northern Australia (2018)
DOCUMENT Citation Only Karen Steelman. Liam Brady. John Bradley. Amanda Kearney.

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;...


Deptford Settlement in South Carolina (2019)
DOCUMENT Citation Only Keith Stephenson. Karen Smith.

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...

Archaeological excavations conducted from 2009-2018 at the Cooper's Ferry site in west-central Idaho revealed a long record of repeated human occupation encompassing the late Pleistocene to early Holocene periods. Lithostratigraphic unit 3 (LU3) is a loess deposit found near the bottom of the site that...


Evaluating Chronological Hypotheses by Simulating Radiocarbon Datasets (2019)
DOCUMENT Citation Only Ian Jorgeson. Ryan Breslawski. Abigail Fisher.

This is an abstract from the "Novel Statistical Techniques in Archaeology I (QUANTARCH I)" session, at the 84th annual meeting of the Society for American Archaeology. Evaluating chronological hypotheses using complex radiocarbon datasets is challenging. Sources of variability, including measurement error, interlab variability, uncertainty associated with the radiocarbon calibration curve, the inherent randomness of the physical processes of radiocarbon formation and decay, and potential...


Fremont Maize Cultivation and Latest Holocene Climate Variability in the Cub Creek Archaeological District, Dinosaur National Monument (2018)
DOCUMENT Citation Only Judson Finley. Erick Robinson. R. Justin Derose. Elizabeth Hora-Cook.

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...
