Left and right, archaeologists are radiocarbon dating objects: fossils, documents, shrouds of turin they do it by comparing the ratio of an unstable isotope, carbon-14, to the normal, stable.
In this way, sites that do not have radioactive or other materials for dating can be given a reliable age estimate molecular clock this method compares the amount of genetic difference between living organisms and computes an age based on well-tested rates of genetic mutation over time.

The most common way to determine the age of an object containing organic material, say fossils, is by radiometric dating, the most common method being radiocarbon dating the most common isotope of carbon is carbon-12, meaning that an atom thereof has 12 neutrons. Absolute dating is used to determine a precise age of a rock or fossil through radiometric dating methods this uses radioactive minerals that occur in rocks and fossils almost like a geological clock. Our understanding of the shape and pattern of the history of life depends on the accuracy of fossils and dating methods some critics, particularly religious fundamentalists, argue that neither fossils nor dating can be trusted, and that their interpretations are better.
Scientists use two kinds of dating techniques to work out the age of rocks and fossils the first method is called relative dating this considers the positions of the different rocks in sequence (in relation to each other) and the different types of fossil that are found in them.
You can learn more about fossils, dinosaurs, radiometric dating and related topics by reading through the links below other dating methods radiometric dating isn't the only method of determining the age of rocks.
When someone mentions scientific dating methods, the first thing to come to mind for most people is carbon dating however, there are many methods that can be used to determine the age of the earth or other objects.
Instead, other methods are used to work out a fossil’s age these include radiometric dating of volcanic layers above or below the fossils or by comparisons to similar rocks and fossils of known ages. Fossils and relative dating fossils are important for working out the relative ages of sedimentary rocks throughout the history of life, different organisms have appeared, flourished and become extinct. Radiometric dating or radioactive dating is a technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed the method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form.
