It is further theorized that since all isotopes of the same element are chemically identical, they should be removed in proportional amounts, forming a straight line on the concordia diagram, that crosses the concordia curve at both the crystallization and the contamination date. In this article we shall discuss how fossils can be used for the purposes of absolute dating. As a result it forms a straight horizontal line on a graph. Isochron dating has been developed in an attempt to solve such problems. So in this case we would have to conclude that this fossil species is between 14 and 16 million years old wherever we find it, even in those cases where there are no datable rocks that we can compare it to. This problem is made worse because other types of crystal defects can easily be counted as fission tracks. Advantages of the method[ edit ] There are three main advantages of using fossils for dating in this manner. Hence we can use datable rocks to put dates on fossil species; and then we can use the fossil species to put dates on other rocks which would otherwise be difficult to date. Sandstone with fossil shells. Third, by the same token, it's much cheaper.

    Because fission-track dating requires a manual count of the fission tracks, the process is more prone to human error and bias than other radiometric dating methods.

    For example, suppose that using stratigraphic methods , we can show that a particular fossil is always older than rocks which are 14 million years old or less, and always younger than rocks which are 16 million years old or more, whenever we are in a position to make a comparison. Hence we can use datable rocks to put dates on fossil species; and then we can use the fossil species to put dates on other rocks which would otherwise be difficult to date.
