A body fossil is part of the body of an organism, or the mould or cast of that part: a shell, a bone, a tooth, a leaf, and in rare deposits a soft tissue. A trace fossil is a structure that an organism made by its activity in or on a sediment or a rock: a track, a trail, a burrow, a boring, a feeding pattern.
