How do fossils form?
After a living organism dies, it may quickly become covered in sand or mud. Once covered, the soft parts rot away. The harder parts, such as bones, teeth, or woody stems, last much longer. Over many years, minerals from the soil slowly replace this once-living material. What remains is a rock like copy of the original!!!
