A relative dating activity paleontologists use fossils to give relative dates to rock strata rocks to help determine their age scientists also use direct . 5) to use radiometric dating and the principles of determining relative age to show how ages of rocks and fossils can be narrowed even if they cannot be dated radiometrically return to top materials required for each group. Scientists can use scientific tests to determine the age of rocks near the fossils the types of tests are called radiometric dating there are certain types of elements that are radioactive.

Scientists determine the age of dinosaur bones by dating the fossils and the surrounding rocks do scientists know the bones are really 68 million years old . One way that helps scientists place fossils into the correct era on the geologic time scale is by using radiometric dating also called absolute dating, scientists use the decay of radioactive elements within the fossils or the rocks around the fossils to determine the age of the organism that was preserved.
