Fossils up to 75,000 years old can be dated with Carbon-14.
Radio isotopes can be used for the age determination of the fossils. Carbon-14 is a common isotope which is used for that purpose. But the half- life of the Carbon-14 is relatively small as 5730 years. That means the amount of Carbon-14 will be half after every 5730 years. Hence, decay is very fast. So Carbon-14 cannot be used forage determination which is more than 75000 years due to the low accuracy.

Explanation:
Basic Science normally focuses on the information that is required by general public. These questions aims to explain the basic knowledge and research to the public who does not belong to medical backgrounds.
Applied Science aims to detailed and more deep research. It focuses on practical application and required every detail about a certain process. It aims to develop more practical application by application of basic research and scientific knowledge.
