Question

how do we know age of fossils

Answer 1

There are two main methods to date a fossil. These are:

absolute dating methods that tell us the actual age (in years) of an object. There are many absolute dating methods. Nearly all of these methods make use of radioactive elements that occur naturally in various types of minerals and organic matter.

relative dating methods that can only tell us whether one object is older or younger than another – they cannot pinpoint an actual age in years. Relative dating methods are used to work out the chronological sequence of fossils. They can be applied to fossils found at a particular site and can also be used to make comparisons between sites.
