Radiocarbon dating legacy collections: A Bayesian analysis of high-precision AMS 14C dates from the Par-Tee site, Oregon

摘要: Abstract Archaeological materials in museum collections provide an excellent opportunity for researchers to investigate social, cultural, and environmental change. However, the precision of archaeological analysis interpretation is dependent on a firm understanding site chronology. The Par-Tee (35CLT20), located northern Oregon Coast, produced large collection including artifacts faunal remains excavated 1960s 1970s. Radiocarbon dates have been obtained from by several different since 1970s, but these data not adequately assessed chronometric hygiene. To establish reliable chronology site, we new high-resolution accelerator mass spectrometry (AMS) radiocarbon collagen peptide fingerprinting cervid bones throughout site. We evaluate along with previous using hygiene assessments Bayesian statistics build refined collection. Previous research suggests habitation occurred between 350 cal BC cal AD 1150. Our reassessment primary cal AD ~100–800. also identified evidence subsequent occupation around ~1490–1635 supporting interpretations after shell midden forming occupation. latter may be associated change use semi-sedentary village cemetery.
