Radiocarbon Dates from Iron Age Gordion Are Confounded
K. DeVries et al. recently presented 14C dates from Iron Age Gordion.1 They claimed that those dates require a destruction date for the site during 827–803 BC (95%-confidence range), which is a century or more earlier than the dates previously proposed. Herein, their claim is examined. (DeVries et al. also claimed artefactual support for their earlier date. O. Muscarella, however, has argued th...
متن کاملCalibration of a radiocarbon age
The calibration of a radiocarbon age to a calendar date is reviewed. It is shown that the commonly-used programs for calibration sometimes give results that are significantly in error.
متن کاملRadiocarbon Dates from a Holocene Deposit in Southwestern Australia
A radiocarbon chronology has been developed using shell, bulk peat, and paired charcoal and pollen preparations from a peat and clay sequence in southwestern Australia. The results indicate the sequence is of Holocene age, and the mid-Holocene was a period of rapid sediment deposition. The earliest record is based on Bothriembyron sp. snail shell and there is a strong indication that the deposi...
متن کاملRadiocarbon dates on bones of extinct birds from Hawaii.
Bones from a stratified sedimentary deposit in the Puu Naio Cave site on Maui, Hawaiian Islands, reveal the late Holocene extinction of 19 species of birds. The age of the sediment and associated fauna was determined by direct radiocarbon dating (tandem particle accelerator-mass spectrometer; TAMS) of amino acids extracted from bones weighing as little as 450 mg. The 14C dates indicate that sed...
متن کاملSpatial gradients in Clovis-age radiocarbon dates across North America suggest rapid colonization from the north.
A key issue in the debate over the initial colonization of North America is whether there are spatial gradients in the distribution of the Clovis-age occupations across the continent. Such gradients would help indicate the timing, speed, and direction of the colonization process. In their recent reanalysis of Clovis-age radiocarbon dates, Waters and Stafford [Waters MR, Stafford TW, Jr (2007) S...
