This paper synthesizes and evaluates settlement and subsistence patterns in relation to landscape change for the entire prehistoric period on the Georgia coast. The dynamic coastal processes of the region have altered the topography and distribution of resources, including those important to humans. These processes were neither uniform in space nor time, with variations leading to the creation of micro-habitats. We assess these habitats individually and as part of a complex whole, to better...

In this paper, we report results from ongoing research on the Iapodian culture, a distinct group centered in the Lika region of modern-day Croatia. Despite excavations in the area since the late 1880s, the scope of Iapodian involvement in regional interaction spheres, larger trade networks, and the general Iron Age world is unclear, and has yet to be systematically analyzed with modern methods. Preliminary isotopic results from Iapodian samples demonstrate an increase in millet consumption,...

Recent advances in ancient DNA (aDNA) analysis have helped to shed new light on long-standing archaeological questions. Researchers can now study how elites and commoners may have been genetically related, the genetic heritage of the first migrants to a particular area, how ancient populations are related to modern groups, and more. While such revelations have been of critical importance to archaeology, results from recent analyses have implicated that ancient DNA analyses can also be applied to...

A contextual analysis of 3,989 radiocarbon dates provides unprecedented insights into 8,000 years of prehistoric adaptions and social evolution in the northern Chihuahuan Desert of southern New Mexico and Trans-Pecos Texas. The chronology is particularly robust between 4500 BP and historic times, allowing for distinctive subsistence, technological, and social developments to be isolated throughout the terminal Middle Holocene and Late Holocene and corresponding Middle Archaic, Late Archaic, and...

The initial results of a radiocarbon local marine reservoir correction study are presented for Prince Rupert Harbor in northern British Columbia, Canada. These preliminary results are integrated into a series of Bayesian age-depth models that illustrate how shell-midden accumulation rates can dramatically vary. Village development in the harbor is discussed in the light of these new findings. SAA 2015 abstracts made available in tDAR courtesy of the Society for American Archaeology and Center...

For more than half a century Paleolithic archaeologists have grappled with radiocarbon-based chronologies that are often contradictory and imprecise. Several key debates in the Palaeolithic have their roots in basic issues related to chronology; did the Aurignacian predate the Chatelperronian in some regions of Europe? When did Neanderthals disappear? How long did anatomically modern humans (AMH) and Neanderthals overlap, and what implications did this have for interaction, acculturation or...

This presentation will reflect on the so called four ‘Radiocarbon Revolutions’ and their implications on archaeological narratives and theory generally, and Neolithic studies in Britain specifically. The timing of this reflection is critical given the implications of recent Bayesian analysis in order to produce precise, robust and probabilistic chronologies for parts of European prehistory. This paper will revisit the reactions to the initial radiocarbon revolutions by important theorists such...

This is an abstract from the "Practical Approaches to Identifying Evolutionary Processes in the Archaeological Record" session, at the 84th annual meeting of the Society for American Archaeology. A causal connection between archaeological events is frequently little more than a convenient assumption. The repeated occupation of a site, the occurrence in time and space of a ceramic ware, or the phases of settlement construction are all assumed to reflect some causal sequence, but it is far from...

Ancient DNA research is revealing unprecedented information about past human migrations and residency. During the late Holocene people exploited food and material resources near Mule Spring Rockshelter in the Spring Mountains of Southern Nevada. In the 1960s hundreds of chewed plant remains (quids) were recovered from the shelter deposits. To better constrain patterns of human residency, mitochondrial DNA (mtDNA) was extracted and partially sequenced from twenty representative quids that have...

In this paper, we present preliminary paleodietary data and radiocarbon dates for 12 burials recovered from Cerro Magoni, an Epiclassic (ca. AD 600-900) hilltop settlement in Tula, Mexico. Stable carbon (δ13C) and nitrogen (δ15N) analyses of bone collagen were used to assess the diet of individuals buried near the summit of the settlement. The production of bone collagen requires essential amino acids derived from protein, therefore stable carbon analyses reflect the origins of dietary protein,...

This paper will present some current work in (i) NE North America (northern Iroquoia), (ii) NW Mexico, and (iii) the East Mediterranean-Caucasus using radiocarbon (14C) dates integrated with archaeological/historical and/or dendrochronological information to try to achieve high-resolution chronologies via Bayesian chronological modelling. The paper will discuss and investigate the potential to achieve much greater precision which, through defining new chronologies, can in turn be transformative...

When radiocarbon dating archaeological material, it is paramount to understand how the object was conserved and which conservation products were used in order to determine: 1) the best location on the artifact to sample; 2) how to remove the consolidant physically and/or chemically, and; 3) whether or not the consolidant was successfully removed. The archaeologist usually knows the approximate age of the artifact given the context in which it was found so when the radiocarbon age is not as...

The Western Stemmed Tradition (WST) is an early cultural phase on the Columbia Plateau of Western North America. Much of the seminal work establishing the timeframe of WST is now decades old and suffers from imprecise dating. In this poster, we review previously compiled data, update stratigraphic interpretations, and model existing radiocarbon assays within a Bayesian framework. Preliminary results indicate that WST on the Columbia Plateau is at least coeval with Clovis and spanned at least...

The Gault site is a lithic procurement site and campsite in Central Texas with components ranging from earlier than Clovis to the Late Prehistoric. For the most part, absolute dating at Gault has relied on optically stimulated luminescence (OSL), which has a high standard error. AMS dating on sparse charcoal samples has been conducted as well, but with mixed results. In particular, the charcoal from the Clovis and lower strata failed to yield viable radiocarbon dates. While faunal preservation...

One of the most enigmatic human dispersals into the Pacific is the colonisation of the Mariana Islands. Here the interpretation of radiocarbon (14C) dates from early settlement sites are hotly debated. One interpretation suggests the Marianas were colonised directly from the northern Philippines around ~3500 BP. However, the age of one of the earliest Mariana sites; Bapot-1, has recently been revised down to ~3200-3080 cal. BP following research by Petchey et al. (in press) which demonstrated...

We present the results of a simulation based test for the existence and significance of two known demographic event horizons. We extend the Shennan et al. (2013) summed probability distribution frequency method to provide a value of statistical significance for the period between two defined calendar dates. Case-study one extrapolates population data from the Western historical record relating to the catastrophic European Black Death and finds a consistent statistically significant drop in...

This is an abstract from the "Late Pleistocene Stemmed Points across North America: Continental Questions and Regional Concerns" session, at the 88th annual meeting of the Society for American Archaeology. The Jones-Miller Bison Kill site was excavated in the early 1970s is dated to approximately 8000 BCE. The age of the site was initially represented by only four radiocarbon dates, only one of which was from the bison bone bed while the remainder came from charcoal samples associated with...

Recently I performed a reevaluation of published radiocarbon dates for the Moche culture (200-900 AD). I only considered 14C samples obtained from short-lived plant materials found in association with "datable" ceramics (Moche I-V, and Early, Middle, and Late Moche). The purpose was to test the validity of the relative ceramic chronologies in each valley against absolute dates. For this paper, using Bayesian analysis I compare the well contextualized Moche dates from the Chicama Valley to...
