The fossil's date will lie somewhere between the ages of the igneous strata above and below the fossil's layer. If the fossil is. There are a variety of techniques. If there is carbon remaining, carbon dating can be utilized for samples up to about 50, years. Many fossils are even older and very ofter the carbon has been replaced completely by mineral.
