Carbon-14 Dating: An Invaluable Yardstick in the Chronology of Humans Archaeologists utilize several methods to analyze data from the past. One scientific tool helps to analyze the radioactive decay of chemical elements found in plant and animal remains‚ pottery‚ and even rocks. Radiocarbon dating‚ also known as carbon-14 dating‚ has developed into one of the most important radioisotope dating methods archaeologists employ. This scientific tool‚ first developed by Willard F.
