How can you determine the age of the fossils?

उत्तर
The age of fossils is determined by measuring the radioactive elements such as carbon-14, uranium-238, potassium-40, or lead-206 present in the fossil or the surrounding rocks. The rate of decay of these elements helps scientists calculate the fossil’s age accurately.
