What are fossils?

The Latin word 'fossil' means'belonging to the past' Or 'buried'. Fossils are the underground remnants of living organisms that existed much earlier. They are formed when a dead plant and animals is preserved in stead of getting decomposed.

This usually happens when the carcass of an animal falls in to a swamp Or gets covered with sand and dust and oxygen is unable to reach the body of the animal and decompose it.

nIn this condition, body parts, such as sells, bones, scals, and sometimes hairs, get preserved. Even traces or heaps of dung can be preserved as fossils.
