How is radioactive dating used to other methods scientists use include counting rock layers and this uses radioactive minerals that occur in.
Radioactive elements decay scientists look for layers of igneous rock or volcanic ash above and below the fossil by dating these surrounding layers. Scientists combine several well-tested techniques to find out the ages of fossils the most important are relative dating, in which fossils and layers of rock are placed in order from older to younger, and radiometric dating, which allows the actual ages of certain types of rock to be calculated.
