Radiocarbon dating can be used to determine the age of

A fossil can be studied to determine what kind of organism it represents, how the organism lived, and how it was preserved.

By definition, D* = N-1) (2) Now we can calculate the age if we know the number of daughter atoms produced by decay, D* and the number of parent atoms now present, N.) is only 5,730 years—that is, every 5,730 years, half of it decays away.After two half lives, a quarter is left; after three half lives, only an eighth; after 10 half lives, less than a thousandth is left.The age of the fossil must be determined so it can be compared to other fossil species from the same time period.Understanding the ages of related fossil species helps scientists piece together the evolutionary history of a group of organisms.Despite seeming like a relatively stable place, the Earth's surface has changed dramatically over the past 4.6 billion years.
