How do you tell how old a fossil is by the rock layer?

You can determine the relative age of a fossil by looking at the position of the fossil in the rock layers. The closer a fossil is to the surface, the younger it is relative to fossils found deeper in the layers. To determine the absolute age of a fossil, scientists use radiometric dating techniques on the surrounding rocks to determine the age of the rock layer the fossil is found in.
