Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages.There are two main methods determining a fossils age, relative dating and absolute dating

Which is the true fossil type?

True form fossils are formed by a process called petrification. Common examples of these fossils include limbs, torsos, fingers, and heads. Unlike molds and casts, they are not formed using an impression. Rather the part of the organism is displaced by minerals that harden to become rock.

What is not a fossil type?

Very recent remains that havent been buried or have only been buried very shallowly, or have not been altered by long periods of time, are not considered fossils. This would include shells on the beach or a skeleton of a recently dead animal.
