- This results from removal of all but the carbon elements. Other elements such as hydrogen, oxygen, and nitrogen are removed.

Animal fossils contain hydroxyapatite from bones.Plants contain carbon.

Fossils are produced by a combination of heat pressure in the earth crust. Prehistoric plants and animals created fossil fuels.

What is electrical energy produced by burning fossils to produce heat, which turns the generator.
Carbon dioxide
Carbondating is the method often used to date fossils, and that involves both the elements Carbon-12 and Carbon-14.
