Question and answer
How do geologists use fossils to determine rock ages? What are these fossils called?
Paleontologists determine the age of fossils by using two main methods of dating; comparative or relative dating infers the age of the fossil by determining the age of the rock where the fossil was found; absolute or chronometric dating uses the [ radioactive decay of isotopes in the rock to determine the geologic age. The procedures for measuring radioactive decay are complex and require the
use of expensive scientific equipment; however, by utilizing the available data from previously dated materials, you can determine the approximate age of similar specimens from other locations. Read more: How to Determine the Age of a Fossil | eHow.com ]
