An interesting bit of information - from Science Alert:
A Crucial Archaeological Dating Tool Is Wrong, And It Could Change History as We Know It
One of the most important dating tools used in archaeology may sometimes give misleading data, new study shows - and it could change whole historical timelines as a result.
The discrepancy is due to significant fluctuations in the amount of carbon-14 in the atmosphere, and it could force scientists to rethink how they use ancient organic remains to measure the passing of time.
A comparison of radiocarbon ages across the Northern Hemisphere suggests we might have been a little too hasty in assuming how the isotope - also known as radiocarbon - diffuses, potentially shaking up controversial conversations on the timing of events in history.
The ratio between C12 (stable) and C14 (radioactive) is not fixed - it varies. Oopsie!
