An engineering student is deciding whether to buy multiple term length parking permits or an annual permit. If the impressions are filled by sediment, and that sediment hardens, the fossil is known as "casts." Unlike normal fossils, which reveal the body of an animal in death, trace fossils show us how an animal behaved in life. Trace fossils offer clues into what ancient species may have been doing, in what circumstances, and, in some cases, how they interacted with other species.
