Absolute and relative dating of fossils
Biostratigraphy: An extended version of stratigraphy where the faunal deposits are used to establish dating.Faunal deposits include remains and fossils of dead animals.There are many methods employed by these scientists, interested in the old, to get to know the age of items.It is possible to tell the number of years ago a particular rock or archeological site had been formed.
It is based on the concept that the lowest layer is the oldest and the topmost layer is the youngest.
To find their age, two major geological dating methods are used.
These are called relative and absolute dating techniques.
Absolute dating, also called numerical dating, arranges the historical remains in order of their ages.
Whereas, relative dating arranges them in the geological order of their formation.
