relative and absolute dating
Explanation:
Two methods of dating fossil fuels are -
a) Relative Dating and b) Absolute Dating
a) Relative Dating - In this method, unknown age of fossil A is determined by comparing it with the known age of fossil B via correlation . Such " fossils B" are known as index fossils. These index fossils belong to a specific age group.
Some common example of index fossils are -
brachiopods,
trilobites, and
