GENERAL KNOWLEDGE

Detailed explanation-1: -Fossils are the preserved remains of plants and animals whose bodies were buried in sediments, such as sand and mud, under ancient seas, lakes and rivers. Fossils also include any preserved trace of life that is typically more than 10 000 years old.

Detailed explanation-2: -Organisms with hard parts (bones, shells) have a good chance of fossilization while soft-bodied organisms are rarely fossilized. The enamel and dentin of teeth are harder than bone and as a result, teeth are more likely to be fossilized than other parts of a vertebrate.

Detailed explanation-3: -Fossilization is an extremely rare process that occurs in some sedimentary environments and causes the hard remains of plants or animals to be preserved as fossils in the earth’s crust.
