Any preserved remains, impression, or trace of organisms that lived in the past is called fossil. Examples include bones, shells, exoskeletons, stone imprints of animals, etc.
The time of death of a plant or animal can be calculated by measuring the radioactivity of C-14 and ratio of C-14 to C-12 (non-radioactive carbon) present in their body of the fossil organism. By determining the age fossil. This called carbon dating.
Once the age of fossil been determined, it is easy to gather the information about other past lived organisms. It can be concluded that vertebrates have been slowly originated from invertebrates.
