Thus it is possible in some instances for two samples from a few decades apart to have the same radiocarbon concentration today, and hence the same apparent radiocarbon age.
This happens whenever there is a wiggle in the curve at the time the samples died.
Modern accelerator mass spectrometry (used for radiocarbon dating purposes to separate radiocarbon atoms from stable carbon atoms and count them) is quite precise.
The technology involved is fascinating and impressive.
The petrous part yielded more endogenous ancient DNA molecules than the squamous part of the same bone.
Molecular dating of the Darra-i-Kur mitochondrial DNA sequence corroborates the radiocarbon date and suggests that the specimen is younger than previously thought.
Eight event deposits were identified within peat at this site.Once the radiocarbon concentration in a sample has been measured, the sample's age in "radiocarbon years" is determined mathematically.The radiocarbon age must then be calibrated to determine the sample's age in calendar years.However, because of calibration curve fluctuations, the depositional age sometimes has a wide error range.In this study, we conducted millimeter-scale high-resolution radiocarbon measurements of tsunami deposits at Urahoro in southern Hokkaido, Japan.
