Define absolute dating fossils

It is left for absolute dating to come up with the precise age of an artifact.

This type of dating employs many dating techniques like atomic clocks, carbon dating, annual cycle methods, and trapped electron method.

Similar layers, thousands of miles apart, come from the same period.

So, fossils in those layers come from the same period as well.

Data from fossils are the primary source of information about the history of life on the earth.

Only a small fraction of ancient organisms are preserved as fossils, and usually only organisms that have a solid skeleton or shell.

However, age of deposition does not mean the age of artifacts found in that layer.

Relative fossil dating of ancient species relies upon stratigraphy.

This is the study of layers that make up the Earth's crust.

C-14 has a half life of 5730 years which means that only half of the original amount is left in the fossil after 5730 years while half of the remaining amount is left after another 5730 years.

This gives away the true age of the fossil that contains C-14 that starts decaying after the death of the human being or animal. Absolute Dating • Dating techniques are used in archeology to ascertain the age of old artifacts and a broad classification of these methods bifurcates them in relative dating and absolute dating • Relative dating comes to a conclusion based upon the study of layer formation of rocks.
