Advancing technology has allowed radiocarbon dating to become accurate to within just a few decades in many cases. Since fossil fuels are millions of years old, they no longer contain any measurable amount of Carbon-14.
Does radioactive dating provide an exact date?
Uranium–lead dating method Uranium–lead radiometric dating involves using uranium-235 or uranium-238 to date a substances absolute age. This scheme has been refined to the point that the error margin in dates of rocks can be as low as less than two million years in two-and-a-half billion years.
What is the date range for carbon dating?
500 to 50,000 years The carbon-14 method was developed by the American physicist Willard F. Libby about 1946. It has proved to be a versatile technique of dating fossils and archaeological specimens from 500 to 50,000 years old.
