Fossils are the remains, imprints, or traces of once-living organisms preserved in rock.

Fossils are the mineralized remains of an animal or plant that are placed in rock and kept in petrified form. The two major types of fossils are body fossils and trace fossils. Body fossils include the preserved remains of an organism’s (plant or animals) body, while the trace fossils include the preserved evidence of an animal’s activity such as shells, nests, imprints, and trackways.
