Fossil

A.C.

Fossils are remains or imprints of plants or animals preserved from long ago in the Earth’s crust.  The fossils found by archeologists help provide information to scientists who study the past. Fossils are very important to paleontologists, scientists who study prehistoric life. Fossils that can be found today could have been underwater at one point.  Fossils are usually made from hard parts of dead animals.  When the animal, or anything that can be alive, dies, it would sink to the bottom over the years.  Over time layers of the earth build up over the dead animal and eventually it will form into rock.  The hard parts will form into rock over the years as well.  When an insect or a piece of a plant gets trapped in resin, it forms another kind of fossil. Resin is a sticky matter made from pine and fir trees. When resin hardens, it turns into a rock like matter called amber. The object inside the resin is preserved from then on. All fossils are made from shells, hard parts of a living substance, and rock like materials. All fossils have something in common.
