Radiocarbon dating an archaeological perspective
These results suggest that dog bone should not be used for radiocarbon dating in the absence of modeling to determine fish consumption and that previously reported radiocarbon dates on human bone from the larger region are likely to have FROs given the known importance of fish in regional human diets....such as the abrupt onset and termination of the AHP, which have been generally attributed to strong biogeophysical feedbacks ([Claussen et al ...This test demonstrated that the inclusion of wider range of samples for 14 C dates in Bayesian models improves the precision, but does not affect the model outcome.Therefore, based on our assessments, we advocate a new protocol that works with a much wider range of samples and where outlying 14 C dates are systematically disqualified using Bayesian Outlier Models.Establishing effective chronologies of these events requires the synthesis on multiple 14 C dates.Various 'chronometric hygiene' protocols have been used to refine 14 C dating of island colonization, but they discard up to 95% of available 14 C dates leaving very small datasets for further analysis.
Two mass finds of several dozen weightsfound in two specific trench-like features were subjected to a detailed archaeological and archaeobotanicalanalysis.
