What are Fossils?
- The preserved or dead remains of ancient organisms are called Fossils.
- Fossils of animals are found as woodblock When animals die, they decay and
form a part of the soil’s components.
- Sometimes, they find themselves lodged into hot mud or inside the bark of a tree and some of them also get lodged into the plant resin or
Fossils
- Dead animals are preserved in many places. After the flesh has decayed, the skeleton is immediately filled up with sediments or other
- Some are placed on a substratum which takes the shape of the skeleton and becomes a mould.
- They are like photographs or samples of the ancient flora and
- Some in the form of imprints, while some left behind as carved onto rocks buried deep under the earth. They are called Fossils.

What is Relative estimation?
- Superficial information can be obtained from the placement of these fossils under the surface of the
- When the earth is excavated, the fossils found very close to the surface of the earth are quite
- These organisms lived in the very near past. The fossils buried deep down are records of ages and ages
Relative Estimation
- The correct estimation is to analyze the different isotopes level in these fossils. If those levels are compared with the levels existing today, the time period of the existence of the species can be calculated. This method is called Relative estimation.
- This method helps to trace
