- They are useful in comparing the characteristics of the organisms.
- We can determine the time of its death and read about that particular period.
- The organs present today can be compared to them to know the similarities and dissimilarities.
- We can know about common ancestors.
- We can predict the age of the Earth and the first residents here.
Note: Fossil usually includes the extinct species which no longer exist now. Palaeontology is the study of the fossils.
