Question

what is fossil and how the age of fossil determined?

Answer 1

A fossil is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood, oil, coal, and DNA remnants.

Answer 2

if a dead insect get caught in hot mud , for example ,it will not decompose quickly, and the mud will eventually harden and retain the impression of the body parts of the insect. All such preserved traces of living organisms are called fossil. the age of fossil is determined by seeing the layer of soil how layer under the insect or animal is barried or by seeing the rate of carbon molecule in the dead animals body.
