J. Louis Giddings’ pioneering work in chronology building in Northwest Alaska laid the groundwork for this case study, where we explore differences between the radiocarbon ages of seals and caribou from Late Holocene archaeological sites in the Kotzebue Sound region. Samples were recovered from distinct cultural features like house floors and cache pits which date between 130 and 1600 BP, including two samples from a house excavated by Giddings in Kotzebue in 1941. Our comparisons of radiocarbon...
Paired radiocarbon dating on bioanthropological and textile samples from the Pica 8 Cemetery (Atacama Desert, northern Chile) (2016)
Pica 8 is an inland cemetery of the Late Intermediate Period (AD 900-1450) in northern Chile. Previous stable isotope studies indicate highly variable dietary contributions of marine and terrestrial foods. However, it is unclear whether this variability is related to change over time or to the presence of groups with different origins. In order to evaluate whether these differences are diachronic or synchronic, radiocarbon dates were carried out on 23 samples. Given the high marine consumption...
Rethinking Chronology in Barrow, Alaska: Assessing ∆R Variation and Applying Bayesian Chronological Models (2017)
Over 200 radiocarbon dates from archaeological contexts are available from the Point Barrow vicinity, along northern Alaska’s Arctic coast, which has been occupied by hunter-foragers from the Birnirk period (AD 500–900) to the present day. Stable isotope analysis (δ13C and δ15N) of ancient humans from the Point Barrow vicinity indicates their diets were very rich in marine protein, and therefore interpretation of these radiocarbon dates has been hindered by radiocarbon offsets. Radiocarbon ages...
