A fossil is any evidence of an ancient organism. The remains of the body, such as bones, shells, leaf impressions, etc., are called body fossils. The evidence of animal activity, such as tracks, trails, and burrows, are called trace fossils. This chapter discusses the ways that organisms become fossils and illustrates these concepts with activities that stimulate fossil-making processes.
