Radiocarbon 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 کاملUncertainty in fundamental natural frequency estimation for alluvial deposits
Seismic waves are filtered as they pass through soil layers, from bedrock to surface. Frequencies and amplitudes of the response wave are affected due to this filtration effect and this will result in different ground motion characteristics. Therefore, it is important to consider the impact of the soil properties on the evaluation of earthquake ground motions for the design of structures. Soil ...
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 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...
