Fossils are the preserved remains of ancient life, such as bones, teeth, wood, and shells. Trace fossils represent the presence or behavior of ancient life, without body parts being present. Footprints, worm burrows, and insect nests are examples of trace fossils. The animal must exert muscle power to open the shells, and when their muscles are relaxed the shells close.
