In 2009, several leading researchers in the field established a detailed calibration of radiocarbon dating, based on a careful analysis of pristine corals, ranging back to approximately 50,000 years before the present epoch [Reimer2009].

It is based on the knowledge that living organisms build up their own organic matter by photosynthesis or by using atmospheric carbon dioxide.

For instance, creationist Walt Brown has pointed out inconsistencies in some radiocarbon dates of mammoths -- one part was dated to 40,000 years, another to 26,000 years (and wood surrounding it to 10,000 years), and yet another to between 15,000 and 21,000 years before the present epoch [Brown2001].

However, in the scientific results mentioned by Brown, the dates come from different mammoth specimens.

Radiocarbon dates are usually calculated to one standard deviation.

For example, if a sample is tested and given a radiocarbon date of 1000 BC.

For instance, even in the 1950s, when Willard Libby first developed the process, it was recognized that the scheme assumes that the level of carbon-14 in the atmosphere is constant.
