A fossil is the remains or traces of a once-living plant or animal that was preserved in rock or other material before the beginning of recorded history. The term also is used to describe the fossil fuels (oil, coal, petroleum, and natural gas) that have been formed from the remains of ancient plants and animals.
The word âfossilâ is from the Latin word âfossilisâ meaning âto digâ. Fossils are the remains or evidence of prehistoric plants and animals that have been preserved in rock. Most of-ten, the hard, durable body parts such as bones, teeth, or shells are preserved.
