True. Footprints and trails are indeed examples of trace fossils. Trace fossils are the remains or traces of the activity of an organism, rather than the preserved parts of the organism itself. They provide valuable information about the behavior and movement patterns of ancient organisms. Footprints and trails are formed when an organism walks or moves across soft sediment, leaving imprints behind. These imprints can become preserved and fossilized over time, providing evidence of the presence and behavior of the organism.
