Fossils are dead animals or plants. Fossils are dug under dirt. A fossil has no bones in it. Fossil means “dug up.” Most fossils have to be dug up from the ground and are formed when they are buried by layers of rocks and sand. If a bone is trapped in the rocks or sand it becomes a fossil. A fossil will have the color of the material that surrounds it. Most fossils are made from ordinary rock. However they are made of the material that encases it.
Fossils happen over time when minerals replace the bone. Fossils also must be protected from the elements in order for this to happen. This usually happens quickly after the plant or animal is buried. Fossils are found all over the world. Fossils look and feel like rocks. They are copies of the original bones or other material. Fossils are very old. Some are 10,000 years old. Some are 500,000,000 years old. You can find fossils underwater, in the mountains, on beaches, or in the desert.
