C14 dating range

However, human beings love to see factual precision, and we want to know how old something is.

Please remember that all dating methods, even those termed "absolute," are subject to margins of error. That is a very small amount of possible error range. Modern studies almost always use two or more methods to confirm dating work and to build confidence in the results obtained.

The numbers of C14 atoms and non-radioactive carbon atoms remain approximately the same over time during the organism’s life.

The following article is abstracted from The Biblical Chronologist Volume 5, Number 1. The science of constructing chronologies from tree rings is called dendrochronology. Modern trees are known to produce one growth ring per year. (The idea that ancient trees grew more than one ring per year will be discussed below.) Therefore, by coring a living tree and counting rings from the present backwards, it is possible to determine the year in which each ring grew. The bristlecone pines in the White Mountains of California live to extremely old ages, some in excess of 4,000 years.

Scientists use a technique called radiometric dating to estimate the ages of rocks, fossils, and the earth.

Scientists have developed calibration techniques to adjust for these fluctuations.

While alive, all plants and animals take C14 into their bodies.

The annual growth rings vary in thickness each year depending on environmental factors such as rainfall.

By matching ring-width patterns in a specimen of known age (starting with living specimens) to ring-width patterns in an older specimen, the proper placement of the older specimen is determined.
