«Radiocarbon dating (usually referred to as simply carbon dating) is a radiometric dating method that uses the naturally occurring radioisotope carbon - 14 (14C) to estimate the age of carbon - bearing materials up to about 58,000 to 62,000 years.»

Just because radiocarbon dating has flaws does not mean the dozen other methods for dating objects are automatically bogus which is why the scientific community believes the 4.5 billion year age of the earth, it's because they did not use just a single method of testing to estimate that age, they used several different methods which all confirmed the same approximate age.

Radiocarbon dating only gives scientists a rough estimate of the age of a deposit, he said.

Traditional radiocarbon dating did not work to assess the age of the femur, which was instead estimated using the mutation rate as approximately 124,000 years old.

Along with radiocarbon dating on charcoal remains from human - made fires, these analyses yielded a much more precise estimate for the age of sediments surrounding artifacts at various depths.

A team of researchers from several academic institutions — including the Max Planck Institute for the Science of Human History, Yale University, University of Chicago, the American Center for Mongolian Studies, and the National Museum of Mongolia — used a scientific dating technique known as radiocarbon dating to estimate the spread of domestic horse ritual at deer stones and khirigsuurs.

Normally, radiocarbon dates have error ranges of several centuries, but the researchers could improve the estimates because the smallest sharks measured showed the «bomb pulse» — a huge increase in global radiocarbon released from the hundreds of nuclear weapons tested in the 1950s and»60s.

In the new study, a collaborator with Cooke, John Southon of the University of California, Irvine, used radiocarbon dating on a fragment of that leg bone to estimate that the monkey died 1,477 plus or minus 34 years ago, or somewhere between 505 and 573 A.D.

Using hand - driven cores, augers, and shovels to reveal the sediments blanketing a lowland facing the Pacific Ocean, and using radiocarbon dating to estimate the times of sand sheet deposition, scientists established a geologic history of past large tsunamis.

However, uranium - thorium dating provides much more reliable results than methods such as radiocarbon dating, which can give false age estimates.

Radiocarbon dating compares the amount of radioactive Carbon 14 in organic plants and animals to reliably estimate when the object died.

Radiocarbon dating is a method that provides objective age estimates for carbon - based materials that originated from living organisms.

The earliest calibrated radiocarbon date was used as a prior estimate of the time to the most recent common ancestor for all island fox samples.

Our results suggest that southern island lineages diverged from each other 5470 — 5640 cal BP to 5700 years ago (95 % HPD: 7700 — 3500) based on radiocarbon and genetic date estimates, respectively.

Bayesian phylogenetic analysis in BEAST [36] of all unique mainland and island haplotypes (Fig. 3) used the earliest island fox radiocarbon date as a prior estimate for the coalescence of all island fox lineages.

Although the estimates obtained by radiocarbon dating may more accurately represent the arrival date rather than a divergence date estimate provided by the mitogenomic data, the radiocarbon dates and divergence estimates are very similar.

The age of the cores was estimated using radiocarbon dating and other techniques.
