This is an abstract from the "SAA 2023: Individual Abstracts" session, at the 88th annual meeting of the Society for American Archaeology. It may be a cliché to say that art is a form of symbolic behavior and modern cognition as old as humankind itself. In Europe, recurring evidence of body decoration and artistic expression is associated with the emergence of cultural innovations introduced by Homo sapiens in the Upper Paleolithic. Thus far, the earliest manipulation of animal teeth to be...

This is an abstract from the "New approaches to the intractable problem of dating rock art" session, at the 90th annual meeting of the Society for American Archaeology. Oxalate-rich, glaze-like mineral deposits are commonly found on low-angle surfaces in Australian rock art shelters. The synchronous growth of individual layers in these deposits across the Kimberley region of northwest Australia, suggests an environmental control, though the exact nature of this link is unclear. Some glazes,...

This is an abstract from the "New approaches to the intractable problem of dating rock art" session, at the 90th annual meeting of the Society for American Archaeology. Placing robust age constraints on the production of rock art is difficult because the lack of suitable material for sampling. This is especially true in the case of petroglyphs where ‘paints’ are unavailable. The ARC-funded project ‘Dating Murujuga’s Dreaming’ faces this challenge by trying to identify a chronology for rock...

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...

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...

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...

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...

This is an abstract from the "The Expanding Bayesian Revolution in Archaeology" session, at the 88th annual meeting of the Society for American Archaeology. Seventy years after the Field Museum’s excavation at Tularosa Cave (1000 BCE–AD 1200) in the Mogollon Highlands of west-central New Mexico, its stratigraphic integrity remains a contentious topic. Bayesian analysis on a series of new AMS dates from sandals and corn found within different levels of the cave demonstrate that much of the...

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...

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...

This is an abstract from the "Images of the Uinta Fremont (A.D. 0 - 1300)" session, at the 90th annual meeting of the Society for American Archaeology. The presence of flayed scalps, severed heads, and ears (henceforth referred to as cephasiles) preserved in the archaeological record of the Southwest United States suggest a greater diversity in significance than simply a status-granting warrior’s symbol, as previously thought. In this paper the author makes an argument in favor of three...
