Relative dating and absolute dating of fossils
In the field of Geology, dating is an important term as it is a technique through which evaluation regarding the age and period about the fossil, remains, the archaeologists do valuables and artifacts.
At first, there were not many methods of dating were available, but now with advancement in the technology, we mainly have two types of techniques to ascertain ages of ancient belongings.
The age determined by relative dating is based on the rules of super imposition and the presumed age of strata based on fossils.
The deeper strata is presumed to be older than strata above.
The main techniques used in absolute dating are carbon dating, annual cycle method, trapped electron method, and the atomic clocks.
In radiometric dating, the radioactive minerals within the rocks are used to know about the age of the object or the sites.
Absolute dating(also known as radiometric dating) is based by the measurement of the content of specific radioactive isotopes of which the "half time" is known.
Ager, Derek I can think of no cases of radioactive decay being used to date fossils.
( New Scientist Nov 10 1983 page 425 Both absolute dating and relative dating are determined by the evolutionary timeline and are used to support the evolutionary timeline.
