The Social History of Mogollon Village: A Bayesian Approach (2018)
Emil Haury’s excavation of Mogollon Village in 1933 helped to provide the first overview of pithouse occupation for the Upper Gila and Mimbres Valley areas as well as establishing the Mogollon culture concept. Tree-ring data from Haury’s excavation suggested that the site was occupied from at least A.D. 730 to 900; however, the stratigraphy of the site suggested that the site was occupied prior to A.D. 700. Further excavation work at the site conducted in the late 1980s and early 1990s suggested...
Societal Cycling Influenced by Climatic Variability Among Early Agricultural Communities: Comparative Perspectives from Belize and Croatia (2019)
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. Archaeological studies continue to highlight the extreme variability in sociopolitical responses to prehistoric fluctuations in climate, from the emergence to complete breakdown of hierarchical societies. These processes were likely more volatile among early farming communities with high degrees of...

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. The radiocarbon record from sustained archaeological field research in the Jama Valley of coastal Ecuador has provided a robust dataset for Bayesian chronological modeling using multiple archaeological sites from a valley-wide landscape. This paper delves into greater detail on the development of the model’s prior...
Terminal Classic Ritual Deposits and Reoccupation at Xunantunich, Belize (2023)
This is an abstract from the "SAA 2023: Individual Abstracts" session, at the 88th annual meeting of the Society for American Archaeology. Ritual behavior during the Terminal Classic period (~AD 750-900) in the Belize Valley reflects the ecological and political concerns of the Maya during a time of prolonged drought and balkanization. Following their abandonment, some major regional centers were revisited, often in the context of pilgrimage. These activities left behind expansive deposits,...
Testing the Danube-Corridor-Hypothesis—New Results from Chonometric Modelling of the Middle-Upper Palaeolithic Biocultural Shift (2019)
This is an abstract from the "SAA 2019: General Sessions" session, at the 84th annual meeting of the Society for American Archaeology. The Middle to Upper Palaeolithic biocultural shift is an important turning point for Human Evolution. As Anatomically Modern Humans (AMH) enter Europe, Neanderthals disappear, eventually leaving AMH as the only representative of their species. To understand the trajectory of AMH dispersal, and the processes underlying this biocultural shift, a robust...
Time, Scale, and Community: Hopewell Unzymotic Social Systems (2018)
Timing of Hopewellian developments plays a critical role in developing an understanding of how Hopewell came to be, and what it was. Focusing on the Scioto Hopewell sites studied by the Scale and Community in Hopewell Networks (SCHON), we present the results of 40 new radiocarbon dates obtained from 15 sites including both habitation and earthwork sites. We also undertake an evaluation of previous dates from these sites to come to a more robust understanding of the timing of key Hopewellian...
Timing the Circulation of Nonlocal Materials in Seneca- and Onondaga-Region Sites (2019)
This is an abstract from the "Dating Iroquoia: Advancing Radiocarbon Chronologies in Northeastern North America" session, at the 84th annual meeting of the Society for American Archaeology. In this paper, I evaluate newly acquired AMS radiocarbon dates for Seneca- and Onondaga-region sites, focusing on what these new dates can tell us about the regional exchange of non-local materials in the circa fourteenth- to seventeenth- century ancestral Haudenosaunee homeland (what is today central New...
Timing the Difference: New Radiocarbon Dates for Late Neolithic Sites across the Great Hungarian Plain (2019)
This is an abstract from the "SAA 2019: General Sessions" session, at the 84th annual meeting of the Society for American Archaeology. Over the past six years, the Prehistoric Interactions on the Plain Project has worked to reconstruct multi-scalar patterns of engagement between Late Neolithic (5000-4500 BC) Tisza and Herpály cultural units on the Great Hungarian Plain. By conducting multiple types of analyses on ceramics and chipped-stone tools, it has been possible to model a strongly...
Tracking Early Human Presence in North America and Beringia during the Late Pleistocene through Bayesian Age Modeling (2019)
This is an abstract from the "SAA 2019: General Sessions" session, at the 84th annual meeting of the Society for American Archaeology. The timing of early human presence in the Americas is a debated topic in First Americans research. The variable of time is, after all, fundamental in the study of human dispersal; it forms a base with which to elucidate spatio-temporal patterns, study applicable bio-cultural processes, and frame environmental data. As such, this investigation analyses current...
Update on Research at the Site of Waterfall Bluff, Eastern Cape Province, South Africa (2021)
This is an abstract from the "From Veld to Coast: Diverse Landscape Use by Hunter-Gatherers in Southern Africa from the Late Pleistocene to the Holocene" session, at the 86th annual meeting of the Society for American Archaeology. Excavations at Waterfall Bluff, South Africa, document evidence of occupation in a persistent coastal context from MIS3 to the Middle Holocene. Remains of marine mollusks and fish show for the first time that coastal foraging was a component of some hunter-gatherer...
Using Bayesian Radiocarbon Chronologies in Conjunction with Artifact Inventories to Reconstruct the Timing and Formation of Peri-abandonment Deposits at Baking Pot, Belize (2018)
A variety of functions have been proposed for ‘problematic deposits’ across the Maya lowlands. All of the explanations have archaeological and temporal implications that have rarely been operationalized together to gain better insights into the nature of these deposits. In this presentation, we describe these features as ‘peri-abandonment deposits’, as all proposed explanations imply that the events that led to the formation of the deposits occurred around the time (or after) ceremonial centers...
Village to City: Formative Period Political Evolution in Central Mexico (2018)
Current research has prompted rethinking about the early development of sedentism, agricultural economies, and complex societies in Central Mexico. We discuss new evidence of significant interconnected changes ca.1000 BC that through multiple trajectories involved intensified maize production, expansion of sedentary villages, expanded interaction networks, and increased social complexity. With the establishment of the first cities, the Late Formative saw corporate political economy strategies...
Will Summing of Radiocarbon Dates Unlock Scales of Socio-environmental Transformations? (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. Demography is a key factor in investigating the relationships between population levels, along with resource availability, environmental dynamics, social organization, and mobility. Prehistoric human activities and population levels can be modeled using summed probability distributions of calibrated radiocarbon dates...
