What is absolute carbon dating of fossils

Rated 4.42/5 based on 914 customer reviews

After death the amount of carbon-14 in the organic specimen decreases very regularly as the molecules decay.

Any attempt to make a claim about evolution always comes back at some point to the geologic time scale.

In this interactive, learn how radiocarbon dating works, what it takes to determine a date in the lab, and why it's challenging to pinpoint a date precisely.

The Age of Dinosaurs was so many millions of years ago that it is very difficult to date exactly.

Inscriptions, distinctive markings, and historical documents can all offer clues to an artifact's age.

And if the artifact is organic—like wood or bone—researchers can turn to a method called radiocarbon dating.

Geologists call this the principle of lateral continuity.

A fossil will always be younger than fossils in the beds beneath it and this is called the principle of superposition.
