Radiocarbon Date Recovery from Bitumen- Containing Egyptian Embalming Resins
Human soft tissue specimens obtained by dissection of Greco-Roman Period mummies buried in the Dakhleh Oasis in Egypt's Western Desert had radiocarbon analytical results many of which were substantially older than accompanying artifacts suggested. Mass spectrometry suggested the presence of hydrocarbons. Gas chromatography/mass spectrometry (GCMS) confirmed that the “resin” applied to these bod...
متن کاملTextile Evidence Supports Skewed Radiocarbon Date of Shroud of Turin
The most studied artifact in human history is the Shroud of Turin, a 14 by 3.5 foot sheet of linen with lightly-shaded ventral and dorsal images of an apparently crucified man matching the wounds reported to have been incurred by Jesus of Nazareth. In 1988, Carbon-14 (C-14) dating of a corner section of the cloth produced dates ranging from 1260 to 1390 A.D.(1) This paper presents new evidence ...

متن کاملEmpirical calibrated radiocarbon sampler: a tool for incorporating radiocarbon-date and calibration error into Bayesian phylogenetic analyses of ancient DNA.
Studies of DNA from ancient samples provide a valuable opportunity to gain insight into past evolutionary and demographic processes. Bayesian phylogenetic methods can estimate evolutionary rates and timescales from ancient DNA sequences, with the ages of the samples acting as calibrations for the molecular clock. Sample ages are often estimated using radiocarbon dating, but the associated measu...
