Molds and Casts Carbon Films Preserved Remains Trace Fossils Petrified Fossils How do they form Mineral rich water soaks into cracks and crevices Minerals precipitate and fill the spaces. Various . Fossil Types. . A . Fossil. . is the preserved remains of animals or plants from an earlier era in rock or other geological deposit, often in a petrified state.. There . are. a variety of fossils there are . Remains . of once living organisms.. Form from decay and are buried by sediment.. Sediment hardens into rock and preserves the shape of the organisms..

Fossils have helped determine approximately when life first appeared, when plants and animals arrived on land, and when organisms became extinct.. CONDITIONS NEEDED FOR FOSSIL FORMATION. Whether or not a dead organism becomes a fossil depends upon how well it is protected from scavengers and agents of physical destruction, such as waves and currents.. SCHEDULE. GROUP . A 12/3/18 .
