Two main ways of dating fossils all you need to know about dating services pdf

Absolute dating is the process of determining an age on a specified chronology in archaeology and geology.

Some scientists prefer the terms chronometric or calendar dating, as use of the word "absolute" implies an unwarranted certainty of accuracy.

Most scientists and many Christians believe that the radiometric dating methods prove that the earth is 4.5 billion years old.

The textbooks speak of the radiometric dating techniques, and the dates themselves, as factual information.

Fossils are the preserved remains or traces of animals, plants, and other organisms from the remote past.

There are three main assumptions that must be made to accept radiometric dating methods.

These must be accepted on faith in uniformitarian and naturalistic frameworks.

No bones about it, fossils are important age markers.

Different methods have their own limitations, especially with regard to the age range they can measure and the substances they can date.

A common problem with any dating method is that a sample may be contaminated with older or younger material and give a false age.

For example, techniques based on isotopes with half lives in the thousands of years, such as Carbon-14, cannot be used to date materials that have ages on the order of billions of years, as the detectable amounts of the radioactive atoms and their decayed daughter isotopes will be too small to measure within the uncertainty of the instruments.

One of the most widely used and well-known absolute dating techniques is carbon-14 (or radiocarbon) dating, which is used to date organic remains.
