- Carbon dating remains reliable if we can expect a predictable ratio between the two main isotopes of carbon. If there’s less carbon-14 relative to carbon-12 isotopes, we know the sample has been around for a long time, and if the ratio of carbon-14 to carbon-12 is almost the same, then it’s a relatively young sample1. However, new research shows that commonly accepted radiocarbon dating standards can sometimes miss the mark, calling into question historical timelines2.Learn more:✕This summary was generated using AI based on multiple online sources.
